Organic Sedimentary Rocks: Organic sedimentary rocks are formed from the accumulation of any animal or plant debris such as shells and bones. A rock’s texture is determined by the sizes, shapes, and positions of the grains that make up the rock. An important characteristic of the clastic sedimentary rocks, however, is that all have clastic textures. There are two main types of metamorphic rocks: foliated and non-foliated.
