How are crystalline sedimentary rocks formed

WebCrystalline sedimentary rocks are composed of crystals having formed from a chemical reaction in a solu- tion or from evaporation. The crys- tals can vary in size from very fine (you cannot see them with the na- ked eye) to very coarse. An example of the crystalline rock rock gypsum is pictured below. WebChlorite. Chlorite is the name given to a class of common phyllosilicate minerals found in a variety of rocks. Chlorite, the most abundant green mineral, occurs infrequently on its own. Chlorite is derived from the Greek word for “green,” referring to the mineral’s color. Chlorites’ green color is due to their iron and magnesium levels.
