Calcite - an overview | ScienceDirect Topics
Calcite replacement is an important mark of the frequent movement of local fluids. During the process of replacement, former pores enlarge or form new pores due to the disappearance of replaced minerals. Some pores are filled with newly precipitated ferrocalcite, while it is soluble. As a result, replacement often improves the porosity.
