Getchell 矿床是赋存于沉积岩中的低品位大型金矿床。金以次显微颗粒的形式赋存于富砷黄铁矿中,主成矿阶段矿物组合为金+富砷黄铁矿+石英+雌黄+萤石,雌黄和萤石在这期矿化中沉淀相对较晓,晚成矿阶段包括有雄黄+方解石+黄铁矿+金等矿物。从主成矿阶段石英中的原生和次生含水包裹体获得的压力校正温度为180～220℃,萤石捕获的原生含水包裹体在155～200℃,次生含水包裹体在115～155℃,萤石也捕获
The Getchell deposit is a low-grade, large-scale gold deposit hosted in sedimentary rocks. Gold in the form of secondary micro-particles occurs in the arsenic-rich pyrite, the main mineralization stage mineral combination of gold + arsenic pyrite + quartz + female yellow + fluorite, female yellow and fluorite in this period of mineralization Relatively small precipitation, late mineralization phase includes realgar + calcite + pyrite + gold and other minerals. The pressure correction temperature obtained from the primary and secondary aqueous inclusions in quartz during the main mineralization stage is 180-220 ° C, the primary aqueous inclusions captured by fluorite at 155-200 ° C, the secondary aqueous inclusions at 115-155 ° C Fluorite is also caught
