Greensand Green"sand` (-s[a^]nd`), n. (Geol.) A variety of sandstone, usually imperfectly consolidated, consisting largely of glauconite, a silicate of iron and potash of a green color, mixed with sand and a trace of phosphate of lime. [1913 Webster]

Note: [hand]Greensand is often called {marl}, because it is a useful fertilizer. The greensand beds of the American Cretaceous belong mostly to the Upper Cretaceous. [1913 Webster]
