Physical properties
Massive structure, greenish-blue coloration from secondary copper minerals (like malachite or chrysocolla), dull to earthy luster, hardness varies (often 3-4 for copper minerals, higher for matrix).
Formation & geological history
Forms in hydrothermal veins, porphyry copper deposits, or oxidation zones of copper deposits.
Uses & applications
Primary source of copper metal for electrical wiring, electronics, construction, and alloys like brass and bronze.
Geological facts
The greenish-blue color is a strong indicator of copper. The Statue of Liberty is green due to the weathering of its copper skin.
Field identification & locations
Identified by characteristic green/blue secondary copper minerals and high density compared to common rocks. Often found in mining districts associated with igneous intrusions.
