摘要
江西万年虎家尖银金矿床赋存于中元古界双桥山群第四岩组内，严格受一组北东向韧性剪切带内的构造挤压破碎带控制。矿区已知矿化硅化破碎带１０余条，其中Ⅶ、Ⅵ等矿带具工业利用价值，主要有用组分为银，伴生有用组分为金、铅、锌及硫等。矿床规模巨大，达中—大型。本文着重阐述矿床的矿化特征，并对矿床成因进行了初步探讨。
The Hujiajian Ag-Au deposit,Wannian county,Jiangxi,occurred inthe fouth petrofabrics in the middle Proterozoic Shuangqiaoshan group,was extremely controlled by a set of tectonic compressed fracture zonewithin the Northeast-trending ductile shear zone. There are ten mine-ralized silicification fracture zones known in the district,of whichvII,vI zones,etc have industrial value. The major useful component isAg,while tbe associated useful componets are Au,Pb,Zn and S, etc. Thedeposit is up to them iddle and large scale. This paper puts an emphasis onthe mineralization features of the deposit,and the genesis of the depo-sit has been preliminary discussed.
