TitleEpidote with calcite
DescriptionThis sample contains mostly coarse dark green epidote crystals and salmon colored calcite. Epidote is a silicate with the chemical formula, Ca2(Al,Fe)3Si3O12(OH). It gets its name from the Greek words epi and didonai, to give-over, in reference to one side being larger than the others in many crystals. The field of view here is approximately 9 cm across.
