👉 Paleocrystic is a term used in geology and palaeontology to describe a type of rock that is composed mainly of silicate minerals, such as calcite or quartz. These rocks are typically found in regions with low temperatures and high pressure, often under the influence of water vapor. Paleocrystic rocks can vary greatly in composition and structure from one region to another, but they tend to be less dense and more resistant to weathering than other types of rock.
