摘要
矿床赋存于太古代太华群绿岩系地层中，受近东西向韧性剪切带中缓于轴面的一组张性断裂控制，呈斜切形式产出。沿北东方向富集成矿规律性强，为中低温岩浆热液矿床。成矿物质来源于上地幔或地壳深部，成矿介质为富含ＣＯ＿２、ＣＨ＿４、ＨＣＯ＿３、Ｃｌ￣－、Ｆ￣－等成分的热水溶液，据成矿规律对矿床远景提出预测。
Gold depost occured in strata of greenstone series in Archean era Taihua group,Its occur-rence is the beveling mode under the control of a set of tensional fracture of gently dipping side inthe ductile shear zone near east一west direction.The ore-forming enrichment is mainly situatedaiong north-east direction. The genetic type of the deposit is the low一mesothermal magmatichydrothermal ore deposit.The mineralizing matter stems from upper mantle and deep─crust.Mineralization media is hydrothermal solution enriched CO_2,Cl￣-, F￣- etc,,Basdon mineralization regularity the prospects of deposit have been forecasted.
