Epidota
Epidota is a mineral with formula Ca₂(Al,Fe)₃(SiO₄)₃(OH), in the Silicatos (Sorosilicatos) group. This specimen comes from Cantera de Los Serranos, Orihuela, Alicante, España and joined the Terrium collection in 2024.
Description
Green prismatic crystals of epidote and clinozoisite on a quartz matrix, with the presence of UV-reactive calcite. Formation in a well-developed cavity, with rough textures and color contrast.
History of this specimen
The UV reaction is due to the accompanying calcite, and the piece is representative of the mineralization of Horihuela, with a typical paragenesis. The green fibers and the prismatic structure add interest and aesthetics to this sample from an abandoned quarry.
