Clastic Sedimentary Rocks include Breccia, Conglomerate, Sandstone, Mudstone ...Chert occurs in carbonate rocks that are greensand, limestone, chalk, and dolostone formations as exchange mineral, where it is formed as a result of some type of diagenesis. if where it occurs in chalk or marl, it is called flint.It also occurs in thin beds, when it is a primary deposit (such as with many jaspers and radiolarites).Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the ...The clastic clay particles display a rougher duller texture. So based on these distinctions, we can separate this pile of rocks into these chemical textures and these clastic textures. ... surrounded by chalk.

These clasts are typically transported and deposited by various agents such as water, wind, or ice. The size of the clasts determines the specific type of clastic rock.Roundness (or angularity) is, hence, a measure of how much sediments have been transported by a current. Roundness is different from sphericity, which is, on the other hand, a measure of the shape of a clast. The external outline of a clast can be: – very angular: sharp edges separated by deep incisions. – angular: sharp edges separated by ...
