Biogenic and chemical rock classification
WebBiogenic (bio = living; genic = produced by) components are the living or once-living components of an environment. Abiogenic (a = not) components are the non-living chemical and physical components of an environment. Abiogenic, or “lithogenic” (litho = stone), sand grains are formed as rocks break down through weathering and erosion. WebBiogenic sedimentary rocks: Rocks that form as a result of biologic processes - i.e. rocks made of organismal remains. These can be unaltered, or diagenetically altered to varying degrees: Most calcium …
