It is made predominantly of cryptocrystalline to microcrystalline quartz (silica) and contains radiolarian microfossils.\u003cbr\u003e Mineral class: belongs to the quartz group specifically as a variety of chalcedony or Jasper. Chemically it is composed of silicon dioxide mixed with impurities (like iron and magnesium) that gives it its distinct colours.\u003c\/p\u003e\n\u003cp\u003eCrystal system: trigonal. Because mookaite is microcrystalline you won’t see large distinct visible crystals, instead the silica forms interlocking microscopic Quartz crystals.\u003c\/p\u003e\n\u003cp\u003eRock formation: \u003cbr\u003eOrigin- mookaite is formed from the accumulation of microscopic marine plankton, known as radiolarians. Their silica skeletons fell to the ocean floor during the Cretaceous period (roughly 145-66 million years ago) compacting into siliceous ooze.\u003cbr\u003eThe ooze underwent intense burial,compaction and silica dissolution. Later silica rich groundwater infiltrated the rock, hardening it into porcellanite,while iron and magnesium fluids added its trademark reds yellows and purples.\u003cbr\u003eIt also s found nowhere else on the earth exclusively surfacing near moons creek in the Kennedy ranges.\u003c\/p\u003e\n\u003cp\u003eHardness: 6.5-7.0 on the MOHs scale.\u003c\/p\u003e","brand":"Crystal and fossils","offers":[{"title":"Default Title","offer_id":58413831586179,"sku":null,"price":80.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/2524\/3040\/files\/IMG-9442.heic?v=1783443095","url":"https:\/\/crystalandfossils.co.uk\/products\/mookalite-1","provider":"Crystal and fossils","version":"1.0","type":"link"}
