Geochemical sediments of various types are an aften overlooked but extremely important component of global terrestrial environments .where present ,chemical sediments and residual deposits may control slope development and landscape evolution .increase the preservation potential of otherwise fragile sediments ,provide important archive of environmental change ,act as relative or absolute dating tools and,in some cases ,be of considerable economic importance .chemical sedimentation may occur in almost any terrestrial environment ,providing there is a suitable dissolved mineral source ,a mechanism to transfer the mineral in solution to a site of accumulation and some means of triggering precipitation .however ,given the increased importance of chemical weathering in the tropics and sub-tropics ,they tend to be most widespread in low-latitude regions (Goudie,1973).
