2021-6-5 · Organic sedimentary rocks are rocks that contain greater amounts of organic life. Plants and the remains of life are much of what you would find as organic in these types of rocks. There are other forms of organic life found in sedimentary rocks such as fossilized remains of fish or mammals, however those rocks may not be considered as an organic.

Sedimentary Rocks and the Rock Cycle

2020-8-26 · Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates. There are two types of sedimentary rocks: Clastic and Chemical Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact,
