This rapid coverage shields the wood from oxygen halting typical aerobic decomposition.\u003cbr\u003e2) groundwater heavily saturated with dissolved minerals most commonly silica or calcite,seeps through the sediment into the porous wood cells. As the water flows through,it deposits these minerals filling the empty cell spaces.\u003cbr\u003e3)over thousands to millions of years,heat,pressure and polymerization transform the amorphous silica and water deposits into solid microcrystalline quartz.\u003cbr\u003e4) while pure silica results in clear or white rock, trace elements often infiltrate the fossilization process. Iron oxides produces reds and yellow,carbon creates black and manganese adds purple or pinks.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":58267870265731,"sku":null,"price":18.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/IMG-8741.heic?v=1781719168","url":"https:\/\/crystalandfossils.co.uk\/products\/conifer-fossil-wood-2","provider":"Crystal and fossils","version":"1.0","type":"link"}
