See also:Staffordshire coalfield, &c . The
See also:Paris basin is made of strata similar to those in the London and Hampshire basins . Strictly speaking, a structural basin is formed of rock beds which exhibit a centroclinal dip; an elongated narrow syncline or trough is not a basin . " Rock-basins " are comparatively small, steep-sided depressions that have been scooped out of the solid rock in mountainous regions, mainly through the agency of glaciers (see
See also:CIRQUE) . Lakes sometimes occupy basins that have been caused by the removal in solution of some of the more soluble constituents (rock
See also:salt, &c.) in the underlying strata; occasion-ally lake basins have been formed directly by crustal movements .
