Pagoda alcite

Calcite is a calcium carbonate mineral with the chemical formula CaCO3, which is the most common mineral in natural calcium carbonate, so calcite is a very widely distributed mineral. As a stable form of calcium carbonate, calcite usually exhibits soft, white or gray and transparent characteristics, and its crystal forms are diverse, including needle-shaped, plate-like, granular, blocky, fibrous, stalactite, etc. The name "acilitite" comes from its unique lytic characteristic - it is easy to get many square pieces when knocking on calcite.
