Definition: Evansolidia is a type of sedimentary rock formed from the accumulation of organic matter, particularly plant material, through physical and chemical processes over millions of years. It is characterized by its distinctive composition, which includes large particles such as pebbles or sand grains that are typically about 1-2 mm in size. This rock is often found in marine environments, including estuaries, rivers, and coastal areas where it can accumulate organic matter from the ocean floor.
