EPIDOTISATION Meaning and
Definition
-
Epidotisation refers to the process of the mineralogical transformation or alteration of rocks, primarily igneous or metamorphic rocks, due to the introduction of the mineral epidote. Epidotisation leads to the formation of epidote-bearing rocks or minerals within the existing rock matrix.
The process of epidotisation occurs when fluids, such as hydrothermal or metamorphic fluids, infiltrate the rock and introduce new elements and minerals, primarily epidote. Epidote is a greenish mineral commonly found in medium- to high-temperature hydrothermal environments or as a result of regional metamorphism. These fluids often carry dissolved metals and ions, which react with the existing rock minerals, initiating the alteration process.
During epidotisation, the mineral epidote replaces or grows alongside existing minerals within the rock, causing changes in its overall mineral composition and texture. This alteration process may lead to the formation of distinct mineral assemblages, such as epidote-amphibolite or epidote-gneiss.
Epidotisation can occur in various geological settings, including igneous intrusions, hydrothermal veins, or along fault zones. It is a common process in areas associated with regional metamorphism, where rocks are subjected to high pressures and temperatures.
Understanding epidotisation and its associated minerals is crucial for interpreting the geological history of a region, identifying mineral deposits, and analyzing the fluid-rock interactions that have occurred during the rock's evolution.

Etymology of EPIDOTISATION
The word "epidotisation" is derived from the noun "epidote", a mineral belonging to the silicate group. The term "epidotisation" refers to the process of converting minerals into epidote or altering rocks through the introduction or replacement of minerals by epidote. The word made use of the common suffix "-isation", which denotes the act or process of something, in this case, referring to the transformation or alteration of minerals or rocks into epidote-rich formations.
