Epidotization is a mineral alteration process that involves the transformation of minerals, typically ferromagnesian silicates like pyroxenes or amphiboles, into the mineral epidote. This alteration usually occurs under low-temperature hydrothermal conditions or during metamorphism.
Epidote is a calcium-aluminum iron silicate mineral with the chemical formula Ca2(Al,Fe)3(SiO4)3(OH), and its formation is associated with the introduction of fluids that contain calcium and aluminum. The process of epidotization often leads to changes in the color, texture, and mineral composition of the rock.
In geology, the presence of epidote can provide clues about the conditions under which a rock has undergone alteration, such as the temperature and pressure conditions, as well as the types of fluids that were involved in the process. Epidotization is one of the many ways in which minerals can be altered and transformed within the Earth’s crust.
