#592: Linarite, malachite, quartz, cerussite and cuprite

A Geoscience Digital Image Library

Title	Linarite, malachite, quartz, cerussite and cuprite from Tiger, Arizona, USA
Description	The blue mineral is linarite, PbCuSO₄(OH)₂, and the green is mostly malachite, Cu₂(CO₃)(OH)₂. Minor greenish-gray cerussite, PbCO₃, appears on the left edge. Deep red-brown cuprite, CuO, forms several small patches. Orangish quartz is on the top edge. This sample is typical of oxidized (altered) zones of copper-lead ore deposits. Many spectacular minerals come from such environments, but the many blue and green secondary copper minerals can be hard to tell apart. This specimen is 5 cm across.
