EPIDOTE Meaning and
Definition
-
Epidote is a mineral that falls under the silicate group, specifically the epidote group. It is commonly found in metamorphic rocks and a variety of geological environments. The name "epidote" originates from the Greek word "epidosis," meaning "increase," due to the characteristic increase in volume that occurs when this mineral is heated.
Epidote typically forms elongated prismatic crystals, which are often striated and can be found in various colors, including green, brown, yellow, and sometimes black. Its luster is often described as vitreous to resinous. It has a relatively high hardness, typically ranging from 6 to 7 on the Mohs scale, making it relatively resistant to scratching. The specific gravity of epidote ranges from 3.2 to 3.6.
One of the notable features of epidote is its characteristic pleochroism, meaning it can display different colors or shades when observed from different angles. This property contributes to the diverse array of colors that epidote crystals can exhibit.
Epidote is commonly recognized for its role as an indicator mineral in geological studies, particularly in the field of metamorphic petrology. Its presence and assemblages can provide valuable clues about the conditions under which rocks have undergone alteration or metamorphism. It is also valued as a gemstone and is sometimes used in jewelry due to its attractive colors and its ability to be polished to a high shine. Additionally, small fragments or specimens of epidote are sometimes collected by mineral enthusiasts and collectors due to its aesthetic qualities and intriguing geological significance.
