For collectors, it is especially notable as a prolific mineral and fossil region, with Mindat documenting numerous mineral occurrences and fossil localities across the range, including classic fluorite, native copper, haüyne, marcasite, and conglomerate specimens. The area’s mineralization has made it a well-known source for collectible specimens from localities around Midelt, Mibladen, Aouli, and nearby districts within the range.\u003c\/p\u003e","brand":"Crystal Castle","offers":[{"title":"Default Title","offer_id":49513841885339,"sku":null,"price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0336\/3012\/6217\/files\/f1e91479-f854-42d6-8746-548718e43afe.jpg?v=1789329743","url":"https:\/\/www.overtonfamilyjewels.com\/products\/auction-win-0d54ef2b-d2c1-49e7-bf00-a25b54a26f14","provider":"OFJ's Crystal Castle","version":"1.0","type":"link"}
