Rocks at earth's crust are mostly igneous, sedimentary, metamorphic rocks. Nature and Mode of Origin of earth Igneous rocks: (1) Crystalline rocks & highly minerals content by Marble (2) Non-fossiliferous rocks B OriginMagma based origin from interior of earth by Volcanic origin (Granite, Plutonic or intrusive rocks) Sedimentary: (1) By Fine sediments and extreme of rocks (2) Fossiliferous rocks Metamorphic rocks: (1) These are non-fossiliferous (2) Have nature of rocks it is composed of B OriginFoliation and bending due to contact & thermal metamorphism here due to pressure & temperature rock changes by GneissGranite slateLimestone These deep in doing paleoclimatic, paleomagnetic, geomagnetic studies further of a region
