Sedimentary rock Classification systems | Britannica

Sedimentary rock Sedimentary rock Classification systems: In general, geologists have attempted to classify sedimentary rocks on a natural basis, but some schemes have genetic implications (i.e.,knowledge of origin of a particular rock type is assumed), and many classifications reflect the philosophy, training, and experience of those who propound them.


In addition, a major new thrust of this proposal is to develop, test, and implement new and experimental methods of soil resource assessment in remote areas where conventional survey procedures are not feasible.In a state like Washington, the vital agricultural and forest industries and the non-agricultural users of soils are strongly dependent on a productive and sustainable soil resource.
