👉 Radiatosulcate is a term used in the field of geology to describe a type of sedimentary rock that is composed primarily of calcium carbonate. This rock is typically found in areas where there are high levels of sea water, and it has a soft, mottled appearance due to its high mineral content. Radiatosulcate rocks can range from very fine-grained to very coarse-grained, depending on the specific type of sediment that formed them.
