caliche
1. n. [Geology] ID: 68
A crust of coarse sediments bound by carbonate cement that formed by
precipitation.
2. n. [Geology] ID: 69
A weathered soil rich in calcium carbonate. It forms when lime-rich
groundwater rises to the surface by capillary action and evaporates into a
crumbly powder, forming a tough, indurated sheet called calcrete. Caliche
typically occurs in desert or semi-arid areas. Of particular concern to
geophysicists is the difficulty in acquiring good seismic data when shooting
through a layer of caliche.
3. n. [Geology] ID: 70
A deposit of sodium nitrate that is mined and used for fertilizer in parts
of South America.
