epidote
Epidote is a green to yellow-green mineral commonly found in metamorphic rocks. It is composed of calcium, aluminum, iron, and silicate, and is known for its distinctive color and crystal structure. Epidote often forms in elongated crystals and can be found in various geological environments, including contact metamorphic zones.
This mineral is frequently associated with other minerals such as quartz and feldspar. Epidote is also used in the field of geology to help understand the conditions under which rocks were formed. Its unique properties make it a subject of interest for both collectors and researchers.
