The Xianghualing deposit in Linwu County, southern Hunan, lies in the Nanling belt, one of China's great tin and tungsten regions. In the Late Jurassic, a highly evolved granite pushed into Middle Devonian carbonate rocks. Hot fluids rich in fluorine and boron poured out of the cooling magma and reacted with the limestone, forming a skarn.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eGeologists split the deposit into four stages, from garnet-forming fluids above 500 °C to late veins below about 230 °C. Fluorite formed alongside tourmaline in the skarn, and calcite came in the late, cooler sulfide stage with quartz, sphalerite and galena. As the fluids cooled and mixed with groundwater, they dropped their minerals into open spaces.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eXianghualing is a large tin deposit, estimated at about 250,000 tonnes of tin and 850,000 tonnes of lead and zinc, plus niobium and tantalum. It is also the type locality of hsianghualite, a rare lithium-beryllium mineral first described from this mine. The mine's name means \"fragrant flower\".\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eAt 30 cm and 5.8 kg, this is a large display piece of fluorite on calcite from the locality.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eIn crystal traditions, fluorite is associated with clarity and focus, and calcite with cleansing energy.\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eChemical Composition\u003c\/b\u003e: Fluorite: CaF2\u003cbr\u003eCalcite: CaCO3\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eChakra\u003c\/b\u003e: Heart \u0026amp; Crown\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eSize \u003c\/b\u003e: 30cm x 22cm x 10cm\u003cbr data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eWeight\u003c\/b\u003e: 5.8kg\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eQuantity\u003c\/strong\u003e: 1pc (Stand not included)\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003ci data-mce-fragment=\"1\"\u003eWith this product, you will get the actual stone in the photograph.
