The Carbonate Mineral: Earth's Chalky Record-Keeper
A carbonate mineral is any member of a large group of minerals where the fundamental anionic structure is the carbonate ion, (CO₃)²⁻. This simple trio of one carbon atom bonded to three oxygen atoms is the common thread weaving through a vast and geologically crucial family. These minerals are far from rare curiosities; they are some of the most abundant and significant minerals on our planet, forming the bedrock of entire landscapes and holding a key to understanding Earth's history.
