apatite
This type of sedimentary rock must have organic material to be created. They are called organic because they are made from organic material such as grass or plankton that, over long periods of time, becomes a type of sedimentary rock. This organic material can be the organism itself or may be given off from the organism.
Sedimentary rocks can be made from any kind of material, from other rocks to shells to plant material. Basically, any rock, from metamorphic to igneous and even to sedimentary, can be weathered and eroded. These particles and grains can be carried great distances by wind, water, ice, etc. before they are deposited and lithified (cemented) back together to form sedimentary rocks.
