What Defines the Carbonates Group
Minerals built around the carbonate ion (CO₃²⁻). Calcite and aragonite (both CaCO₃) are the most common, but the group includes vividly colored members like rhodochrosite (pink, manganese), malachite (green, copper), and azurite (blue, copper). All effervesce in acid, the classic field test.
