Malachite is a vibrant green mineral from the Congo, known for its striking banded or layered patterns.
Geological Information:
- Location: Congo (Democratic Republic of Congo) - Type: Copper carbonate mineral - Formation: Formed through the oxidation of copper ore, typically in limestone and dolostone rocks. - Age: Varies, but most deposits are from the Precambrian era (over 541 million years old). - Color: Bright green to pale green, often with banded or layered patterns. - Hardness: 3.5-4 on the Mohs scale, relatively soft.
Malachite is a secondary mineral, formed through the weathering of copper deposits in the Congo's ancient rocks, creating its distinctive patterns and vibrant green color.
