text: Grains that have been cemented together. Can sometimes be rubbed off easily.\n\nEasily friable. (breaks off in small pieces)\n\nLayering due to deposition. (ie shale is in layers)\n\nDull, earthy appearance.\n\nNo crystal formations. (unlike meta. & ign.)\n\nFossils. (ie fossiliferous limestone; metamorphic may have some "warped" unidentifiable fossils but more than likely won't; it is impossible for ign. rocks to contain fossils b/c of complete melting of rock)
