中文摘要:近年，在中国赣南的会昌县年坑地区新发现一浅成低温热液银矿床，其矿体赋存在隐爆角砾岩筒内，隐爆角砾岩的胶结物由富锰碳酸盐类矿物（含锰白云石-锰白云石-菱锰矿-含锰方解石）-石英-白云母-含银硫盐（黝铜矿-硫银锗矿）-硫化物（辉银矿、方铅矿、半透明闪锌矿和黄铁矿）-自然银组成，成矿具有中硫化型特征。年代学研究表明，年坑银矿床形成于三叠纪（印支期），是华南地区首例印支期中硫化型的浅成低温热液矿床。对该矿的成矿时代和成矿特征的详细研究，指示华南地区具有寻找印支期同类型浅成低温热液银矿及相关斑岩钼或锡矿床的潜力。
Abstract:Recently, a new epithermal Ag deposit was discovered in the Niankeng area of the southern Jiangxi Pro-vince, South China. The Niankeng Ag deposit is hosted in a breccia pipe, which was cemented by the manganese-rich carbonate species (Mn-dolomite-kutnohorite-rhodochrosite-Mn-calcite)-quartz-muscovite-Ag-bearing sulfosalt (tetrahedrite-argyrodite)-sulfide (argentite-galena-translucent sphalerite-pyrite)-natural silver. The deposit is characterized by intermediate sulfidation. According to geochronologic studies, the Niankeng Ag deposit was formed in the Triassic (Indosinian), and is the first discovered and reported intermediate sulfidation epithermal Ag deposit in the South China. Studies of the mineralization ages and ore characteristics of the Niankeng Ag deposit are conducive to explore the Indosinian intermediate sulfidation epithermal Ag deposits and related porphyry Mo and Sn deposits in the South China.
