Its picturesque painting like patterns are formed by natural mineral infiltration of iron and magnesium oxides that precipitate into ancient tectonic fractures.\u003cbr\u003eRock type: sedimentary rock specifically a fine grained clay rich bioclastic wackestone\/mudstone or marly limestone.\u003cbr\u003eFormation: created about 40-50 million years ago during the Eocene epoch. Tectonic pressure such as the African and European plates colliding fractured ancient seabed limestone. Petcolating groundwater subsequently pushed iron and manganese solutions into the cracks, leaving behind scenic dendritic ruin and landscape patterns.\u003cbr\u003eMineral class: The rock is composed of several key minerals across different classes.\u003cbr\u003eCarbonate minerals- primary matrix and veins. (calcite)\u003cbr\u003eOxide and hydroxide minerals. The pigments: the scenic browns,oranges and black patterns formed by iron oxides e.g hematite or goethite, and manganese oxides.\u003cbr\u003eSilicates:secondary minerals contains microscopic quartz crystals and minor phyllosilicate.\u003cbr\u003eCrystal system: \u003cbr\u003eCalcite-trigonal crystal system \u003cbr\u003eQuartz-hexagonal crystal system \u003cbr\u003eClay minerals\/manganese oxides- monoclinic or triclinic systems.\u003cbr\u003eHardness is 3-4 on the MOHs scale.\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":58252557091203,"sku":null,"price":10.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/IMG-8644.heic?v=1781543909","url":"https:\/\/crystalandfossils.co.uk\/products\/paesina-stone-slice","provider":"Crystal and fossils","version":"1.0","type":"link"}
