Physical properties
Mohs hardness of 3, yellow to white color, vitreous to pearly luster, trigonal crystal system, perfect rhombohedral cleavage, specific gravity of 2.71.
Formation & geological history
Formed in sedimentary environments through the precipitation of calcium carbonate from water, often in caves, hot springs, or marine deposits.
Uses & applications
Used in optical devices, construction materials, lime production, and as a popular mineral specimen for collectors.
Geological facts
Yellow calcite strongly reacts with dilute hydrochloric acid, producing carbon dioxide gas bubbles. It exhibits strong rhombohedral cleavage when broken.
Field identification & locations
Identified easily by its low hardness and fizzing reaction with acid; found worldwide with notable deposits in Mexico, USA, and Madagascar.
