Conichalcite and Chrysocolla from chile Size- 4.4cm x 3.9cm x 2cm Weight- 35g You will receive the item in the photo 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.
