Instead it is a secondary mineral that forms through the weathering and oxidation of primary copper and zinc ore bodies.\u003cbr\u003eIt is strictly found in the oxidized zones (the weathered upper layers ) of copper and zinc deposits. As acidic metal rich water interacts with carbonate rocks like limestone Aurichalcite precipitates out. It typically grows as delicate feathery mat,dusty crusts or tine middle like crystals aggregates coating the cavities of host rocks like limestone or limonite.\u003cbr\u003eIt is commonly found alongside other secondary minerals like malachite,azurite smithsonite,Rosasite and hemimorphite.\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":62972341354883,"sku":null,"price":40.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/FullSizeRender_51c4536a-8629-42ad-9146-bd9de33f34cb.heic?v=1792681973","url":"https:\/\/crystalandfossils.co.uk\/products\/aurichalcite-19","provider":"Crystal and fossils","version":"1.0","type":"link"}
