Conichalcite and Chrysocolla are both visually striking copper rich secondary minerals. While Conichalcite is an arsenate that crystallizes in visible micro-crystals Chrysocolla is a hydrous silicate that is largely amorphous.
Conichalcite:
Mineral class-arsenates
Crystal system-orthorhombic
Rock formation- found as a secondary mineral in the oxidation zones of copper orebodies. It forms when highly oxygenated groundwater reacts with primary copper sulfides/oxides.
Chrysocolla:
Mineral class-silicates
Crystal system-orthorhombic
Rock formation-also formed in the oxidation and weathering zones of copper deposits. It precipitates as a result of water containing dissolved silica interacting with copper minerals,often cementing together to form Botryoidal crusts or being fillings within host rocks.
