Some scholars have divided the development of dolomite into three stages. First, the deposition of Ca-rich carbonate rocks forms the material basis for dolomite formation. Second, limestone or Mg-rich calcite is metasomatized by Mg-rich fluid, which develops along unconformity surfaces, sequence boundaries, and pores (Xiong et al., 2021).

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
