甘肃西和县金崖沟金、锑矿位于南秦岭北部的岷县鹿儿坝—西和崖湾—两当广金坝金、汞、锑成矿亚带上。矿带长约1 km,由一条NE向高角度断层F1控制,矿(化)体主要处于断层的下盘即南东盘,矿体产状280°~315°∠67°~80°,不连续,呈透镜状、扁豆状,在纵向上及垂向上矿体产状均变化较大,形态主要随断层错动形成的虚脱空间形态的变化而变化。金矿呈透镜状、板状、长条状,品位1.05~3×10~(-6),厚度0.78~3.20 m不等,锑品位1.14%~3.41%,平均厚度1.26 m。金矿对岩石有一定的选择性,主要以铅锌铜硫化矿物包裹金形式赋存于断层破碎带中的硅化角砾岩中。锑矿不具规模,多分布于两断层交汇处呈鸡窝状产出,即在构造复杂流体流通较好且有利的容矿空间成矿,呈浸染状、放射状、针状,锑矿与金矿局部伴生,局部独立存在。
Gold and antimony mines of the Jinyugou, Xijian County, Gansu are located in the gold, mercury and antimony metallogenic belt of the Guangxian Dam in the Lugar dam - Xiheya bay - two of the Min County in the southern part of the South Qinling Mountains. The ore belt is about 1 km long and is controlled by a NE high-angle fault F1. The orebody is mainly located in the lower or south-east plate of the fault. The ore body is 280 ° -155 ° ∠67 ° -80 ° Continuous, lens-shaped, lentil-shaped, vertically and vertically on the ore-producing changes are larger, mainly with the formation of the fault shape changes in the shape of the collapse of space changes. The gold mine is lenticular, plate-like and long strip with the grade of 1.05-3 × 10 -6, the thickness of 0.78-3.20 m, the antimony grade of 1.14% -3.41% and the average thickness of 1.26 m. Gold ore has a certain selectivity to the rock, mainly in the form of lead, zinc and copper sulphide mineral inclusions in silicified breccias in the fault zone. Antimony ore is not scale, and is distributed in the intercalation of the two faults in a henna-like output, that is, in the ore-hosting space where the flow of complex fluids is good and favorable, there are disseminated, radial, acicular, antimony and gold Local companion, local independence exist.
