QUEENSLAND , a See also:state of the Australian See also:commonwealth, occupying the whole of the See also:north-eastern portion of the Australian See also:continent, and comprising also the islands in Torres Strait . (For See also:map, see See also:AUSTRALIA.) It lies between 1o° and 29° S., and is bounded on the N. by Torres Strait and the Gulf of See also:Carpentaria, on the W. by See also:South Australia and the See also:Northern Territory, on the S. by New South See also:Wales and on the E. by the Pacific Ocean . It has an See also:area of 668,497 sq. m., a See also:coast-See also:line of 3000, is 1250 M. See also:long and 950 M. wide at its widest See also:part . With so extensive a seaboard Queensland is well favoured with ports on the Pacific See also:side . Moreton See also:Bay receives the See also:Brisbane See also:river, on whose See also:banks Brisbane, the See also:capital, stands . See also:Maryborough See also:port is on the See also:Mary, which flows into Wide Bay; See also:Bundaberg, on the See also:Burnett; See also:Gladstone, on Port See also:Curtis; See also:Rockhampton, up the See also:Fitzroy (See also:Keppel Bay); See also:Mackay, on the See also:Pioneer; See also:Bowen, on Port See also:Denison; See also:Townsville, on See also:Cleveland Bay . See also:Cairns and Port See also:Douglas are near Trinity Bay; Card-well is on See also:Rockingham Bay; See also:Cooktown, on the Endeavour; See also:Thursday See also:Island port, near Cape See also:York; and See also:Normanton and Burketown near the Gulf of Carpentaria . The quiet Inner Passage, between the See also:shore of the See also:Great Barrier See also:Reef, 1200 M. long, favours the north-eastern Queensland ports . Brisbane was founded in 1826, but colonization was restricted until 1842, when the Moreton Bay See also:district of New South Wales was thrown open to settlers . It was named " Queensland " on its separation from the See also:mother See also:colony in 1859 . A broad See also:plateau, from 2000 to 5000 ft. in height, extends from north to south, at from 20 to 100 M. from the coast, forming the See also:Main Range . The Coast Range is less elevated . A plateau goes westward from the Great Dividing Range, throwing most of its See also:waters northward to the gulf . The Main Range sends numerous but See also:short streams to the Pacific, and a few long ones south-westward, lost in See also:earth or shallow lakes, unless feeding the river See also:Darling . Going northward, the leading See also:rivers, in See also:order, are the See also:Logan, Brisbane, Mary, Burnett, Fitzroy, Burdekin, See also:Herbert, See also:Johnstone and Endeavour . The Fitzroy receives the See also:Mackenzie and See also:Dawson; the Burdekin is supplied by the Cape, Belyando and Suttor . The See also:chief gulf streams are the See also:Mitchell, See also:Flinders, Leichhardt and See also:Albert . The great dry western plains have the Barcoo, See also:Diamantina, Georgina, Warrego, Maranoa and Condamine . (T . A . C.) See also:Geology.—Queensland consists geologically of three areas . The eastern See also:division of the state, including all the Cape York See also:Peninsula and the mountainous areas behind the coast, is occupied by the Queensland See also:Highlands, which are built up of a .See also:foundation of Archean and contorted See also:Lower Palaeozoic rocks, upon which See also:rest some sheets of comparatively See also:horizontal Upper Palaeozoic and Mesozoic rocks . The rocks of the Highlands sink to the See also:west below the Western Plains, which consist in the main of a See also:sheet of Cretaceous See also:clays, capped by isolated ridges and peaks of See also:Desert See also:Sandstone . In the far west the plains end against the See also:foot of an Archean tableland, which is the north-eastern See also:projection of the Western Plateau of Australia .
The See also:oldest rocks in Queensland are gneisses and See also:schists, which
regarded as metamorphosed See also:Silurian rocks, which had been converted into See also:gneiss, See also:mica-schists and See also:hornblende-schists
.
Their Silurian See also:age was affirmed owing to their lithological resemblance to rocks in See also:Victoria, which were then regarded as Silurian, but have since been shown to be Archean
.
The gneisses and schists occupy the Barklay Tableland, the Cloncurry See also:Goldfield and the rocks of the Mackinlay district in the west of the state
.
The second chief Archean area is around Charters Towers and the Cape Goldfieid; it includes quartzites, conglomerates and slates, striking from north-west to south-See also:east
.
The third Archean area occupies the See also: The Middle Devonian limestones occur on the See also:Marble and See also:Hunter Islands in the See also:Northumberland See also:Archipelago . The Devonian rocks in the Pentland and Gilbert district are estimated by See also:Jack to be over 20,000 ft. in thickness; but they probably include some Lower Palaeozoic beds . The Queensland Carboniferous See also:system is divided into five series—the See also:Gympie, See also:Star and the three divisions of the Bowen beds . The lowest series is the Gympie, which occurs between Brisbane and Maryborough . It consists of shales and sandstones, and is traversed by dikes of diorite, which often contain See also:pyrites and See also:gold . The age of these gold-bearing rocks is proved by the presence of such fossils as Productus cora and Protoretepora ampla . The Gympie series is well developed in the districts of Burnett, Broad See also:Sound Bay and Wide Bay, along the coast from Port Curtis to the south of Cape See also:Palmerston . The Gympie beds are greatly contorted; and those of the Star series are regarded as younger, because they are less disturbed . They are best known in the basins of the Great and Little Star rivers, tributaries of the Upper Burdekin . They are best developed on the Belyando river and in the See also:Drummond Range, where the shales and sandstones yield abundant fossil See also:fish; on the Star river the shales contain Lepidodendron . The Bowen beds are divided into three series which represent the upper part of the Carboniferous . The Lower Bowen series consists of agglomerates and altered rocks exposed in the See also:Toussaint Range; farther south, the Lower Bowen beds consist of grits, sandstones and shales, which have been altered by some granitic intrusions . The Middle Bowen series contains beds with Productus See also:coca and Glossopteris . The Upper Bowen beds contain See also:coal seams, abundant remains of Glossopteris and one marine See also:band . They See also:form the centre of the See also:basin of the Bowen coalfield; while the Middle Bowen beds outcrop in a band around it . The Upper Bowen beds occur also at Townsville and Cooktown in Northern Queensland . The rocks of the Mesozoic See also:group may be divided into two divisions, of which the lower includes terrestrial deposits containing coal seams; the upper is mainly a marine formation, but it terminates with a further development of terrestrial deposits . The Lower Mesozoic division includes the Burrum and See also:Ipswich series . The Burrum series occurs along the eastern coast from See also:Laguna Bay, through Wide Bay and Maryborough, to See also:Blackwater See also:Creek; and it extends inland for about 30 m., where it is faulted against the Gympie beds . The western edge of the Burrum beds are de-scribed as highly altered in places, by contact with granites . The Ipswich series occupies 12,000 sq. m. in the south-eastern corner of Queensland, and is the northern continuation of the Upper See also:Clarence series of New South Wales . It contains coal seams which have been worked, though the coal is of inferior value to that of the Carboniferous of New South Wales . One seam, on Stewarts Creek, near Rockhampton, is 26 ft. thick . Interbedded basalts occur in the Ipswich beds, forming the scarp of the See also:Toowoomba Range .
The Burrum and Ipswich beds have been included in the Trias and the See also:Jurassic, or in both systems as the Trias-See also:Jura, but according to A

.
See also:Seward their characteristic fossil, Taeniopteris daintreei, is of Lower Oolitic age
.
The Cretaceous system is represented by a lower group of marine clays forming the See also:Rolling Downs formation
.
They are said to rest conformably upon the Ipswich beds, and some of the fossils found in these beds were first described as Upper Oolitic
.
The See also:affinities of the fauna are in part with Lower Cretaceous and in part with the Cenomanian; so both these series may be represented
.
The Rolling Downs formation consists in the main of clays, forming the
Impermeable See also:cover over the subterranean stores of See also:water, which maintain the flowing See also:wells of central Australia
.
The Rolling Downs formation underlies the whole of the Western Plains of Queensland, from the foot of the Queensland Highlands, westward to the Barklay Tableland; and it extends from the Gulf of Carpentaria on the north, across the state into South Australia and New South Wales
.
The Desert Sandstone overlies the Rolling Downs formation
.
Its age is shown to be Upper Cretaceous by some marine fossils from Maryborough and Croydon, which are said to be from rocks inter-bedded in it
.
In the interior, the Desert Sandstone is entirely of terrestrial and lacustrine origin, and the only fossils are obscure plant remains and the silicified trunks of trees
.
Glossopteris has been collected on Betts Creek from a See also:rock identified as Desert See also:Sand-See also: If it had survived into the Cretaceous, some specimens of it would doubtless have been obtained from the coal seams of the Lower Mesozoic . The Desert Sandstone once covered nearly three-quarters of Queensland, having a wider range than the Rolling Downs formation . It was formed partly on See also:land, partly in fresh-water lakes and partly in arms:of the See also:sea, as at Croydon and Mary-See also:borough . There is no trace of volcanic rocks in this See also:period, and the vitreous See also:surface of the Desert Sandstone is due to the deposition of efflorescent chert . The Desert Sandstone formation has now been weathered into isolated plateaus and See also:tent-shaped hills . The See also:Cainozoic group includes many volcanic rocks, mainly sheets of See also:basalt, as at Townsville and Hughenden . Near Herberton, between the See also:head of the Burdekin and the Einasleigh River, the basalts occupy 2000 sq. m. of See also:country . Their age appears to be Oligocene, as they probably correspond with the oldest Cainozoic basalts of Victoria . Volcanic rocks of a later period occur north of Cooktown, and in the Einasleigh River, where the eruptive centres are recognizable; and a series of hot springs, some of which are described as geysers, represent the last See also:stage of volcanic activity . The most important Cainozoic sedimentary rocks are the See also:bone breccias, made up of bones of See also:extinct marsupials, such as Diprotodon, Thylacoleo and See also:giant Kangaroos . They appear to have been bogged in the mud by drying water holes, during droughts . The bones also occur in beds of See also:gravel and sand, and they have been found in places covered by 188 ft. of overlying deposits . Caves occur in the limestones, and on their floors there are beds yielding bones of marsupials and extinct birds; but no well authenticated See also:case of the See also:ancient remains of See also:man has yet been established . The chief See also:mineral product of Queensland is gold, found in See also:veins in Archean, Palaeozoic and Lower Mesozoic rocks . The most famous gold mines are Mount See also:Morgan, now changing into a See also:copper mine, Charters Towers and Gympie . See also:Tin is found in the See also:fields of Herberton, Cooktown and Stannary Hills . Copper occurs near Herberton, Chillagoe and Mungana, coal in See also:southern Queensland in the Upper Carboniferous and Lower Mesozoic deposits . A full See also:account of the geology of Queensland up to 1892 is given in Jack and Etheridge's Geology of Queensland . The tectonic geology of the coast-line has been described by E . C . See also:Andrews, and the See also:general geology is described in the numerous valuable publications of the See also:Geological Survey of Queensland . A See also:summary of the mineral resources was issued by the Queensland See also:government in 1901 . See also:Information regarding the artesian water See also:supply is given in the See also:Annual Reports of the Queensland See also:Hydraulic Engineer . (J .

See also:Flora.—The Queensland flora comprehends most of the forms See also:peculiar to Australia, with the addition of about five See also:hundred See also:species belonging to the See also:Indian and Malayan regions
.
There are no See also:mountain ranges of sufficient See also:altitude to make any appreciable See also:change in the plant-See also:life
.
See also:Bellenden See also:Ker, the highest mountain in tropical Australia, has a height of only 5200 ft., and the See also:plants growing upon its See also:summit, as well as on the highest parts of the neighbouring mountains, are for the most part similar to those on the See also:low lands in the southern parts of the state, and the plants which may be considered as peculiar to these heights are few in number of species
.
They consist of a Leptospermum and a (?) Myrtus, which attain a height of about 30 or 40 ft., and have widespreading, densely leaved heads
.
The most attractive of the tall shrubs are Dracophyllum Sayeri, of which there are two forms, See also:Rhododendron Lochae and Orites fragrans
.
A few See also:orchids of small growth are met with, but the only large species known to inhabit these localities is the normal form of Dendrobium speciosum
.
These high spots have a few ferns peculiar to them, and of others it is the only known Australian See also:habitat; for instance, the See also:pretty See also:
These are mostly trees of large See also:size
.
Other large trees of the order which supply hard, durable See also:timber are the broad-leaved See also:tea-tree (Melaleuca leucadendron and others), " Swamp See also:Mahogany " (Tristania suaveolens), " Brisbane Box " (T. conferta), " See also:Turpentine " (Syncarpid laurifolia), " Peebeen " (S
.
Hillii), " See also:Penda " (Xanthostemon oppositifolius)
.
These are most generally cut at sawmills
.
Other orders, however, furnish equally serviceable, large-sized timber, particularly the following:—" Sour See also:Plum " (Owenia See also:venosa, Meliaceae), " Red See also:Cedar " (Cedrela Toona), " See also:Crow's Ash" (Flindersia australis, Meliaceae), " Burdekin Plum " (Pleiogynium Solandri, Anacardiaceae) ; " See also:Bean-tree " (Castanospermum australe, See also:Leguminosae), " Johnstone River See also:Teak " (Afzelia australis, Leguminosae), " Ringy See also:Rosewood " (See also:Acacia glaucescens, Leguminosae), " See also:Black See also:Walnut " (Cryptocarya Palmerstoni, Laurineae), " See also:
With regard to See also:fodder-plants, no country is better furnished; there are many herbs and a large number of See also:salt bushes and other shrubs, which form excellent auxiliaries to the See also:food supply for stock
.
It is, however, to the See also:grasses that the excellence of the pastures is mainly due
.
On the extensive plains where the best species abound may be seen a large number of the genus Panicum, of which the following are looked upon with the greatest favour:—" Vandyke grass," a form of P. flavidum, " See also:Cockatoo grass " (P. semialatum), on the roots of which a species of cockatoo, in some parts of North Queensland, feeds; " See also:Barley grass" (P. decompositum and P. distachyum) ; " See also:Blue grass " (Andropogon sericeus, A. pertusus, A. ref ractus, and A. erianthoides) ; " See also:Russell River grass " (Paspalum
vlmarra, nearly allied to the South See also:American species P. paniculatum, minutiflorum, and P. brevifolium, Agropyrum scabrum) ; " Tall See also:Oat grass " (Anthistiria avenacea) ; " Landsborough grass " (Anthistiria membranacea) • Danthonia racemosa, D. pilosa, D. pallida, and D. semiannularis; Sporobolus Benthami, an excellent species found near the Diamantina and Georgina rivers, and S. actinocladus; Stipa aristiglumis, Leptochloa chinensis, Microlaena stipoides; " See also:Early See also:spring grass " (Eriochloa punctata), with the following " Love grasses": —Eragrostis Brownie, E. chaetophylla, E. pilosa and E. lenella
.
The " Mitchell grasses " (Astrebla pectinate) and its varieties, viz. the See also:Wheat (traticoides), the weeping (elymoides) and the See also:curly (curvifolia), are those that have the most extra-See also:ordinary vitality, but some stockholders consider that the "See also:Sugar grass " or " See also: One Fig (Ficus gracilipes) produces a fruit used for jam and jelly . Two Garcinias are recorded as indigenous, but of one only (G . Mestoni) is the fruit known . It is of a depressed globular form, sometimes 3 in. in diameter, very juicy, and of a pleasant flavour . Leptomeria acida, one of the very early fruits used by Australian colonists, is met with in some localities . The "Finger See also:Berry " or " Native See also:Loquat " (Rhodomyrtus macrocarpa) makes a See also:good jam, but is in See also:bad repute for use in the raw state, perhaps owing to a peculiar fungus at times found to infest the berries . The Queensland See also:Raspberry (Rubus rosaefolius) is widely spread and commonly used, but the fruit is rather insipid . The representatives of the genus Vitis all belong to the sub-genus Cissus ; several of them, although somewhat acrid, are useful for jam and jelly: probably the best for the purpose is one met with near the See also:Walsh River, V . Gardineri, which is said to bear bunches from i lb to 2 lb in See also:weight, the berries being large and of pleasant flavour . A large number of See also:nut-like fruits are used by the See also:aborigines for food, but the only one used by the white See also:population is the fruit of Macadamia ternifolia, the Queensland nut . The foliage of many plants yields by See also:distillation essential See also:oils, particularly Eucalypts, Backhousias and other Myrtaceous plants. as well as some belonging to Rutaceae and See also:Labiatae, especially the genus Mentha . Apart from plants of economic value, there is a profusion of ornamental plants, shrubs, trees and parasites . Of ferns, one-See also:half of the kinds met with in Australia are found in Queensland as well as in the other states, one-See also:fourth in Queensland alone, the remaining fourth belonging to the other states, but not to Queensland . The indigenous ferns equal in number those of New See also:Zealand, and are three times the number of those of Great See also:Britain . Fauna.—The land fauna of Queensland is essentially one with that of the entire continent . But the See also:geographical position of the state, which exposes it to the See also:climatic and transporting influences of the intertropical Pacific, has to a notable extent impressed on its fauna characters of its own . It has thus been made the headquarters of Australian See also:bird-life on land and fish-life at sea, the moisture of its coastal regions and the warmth of its tidal waters being eminently favourable to that See |
