小秦岭东闯金矿Au/Ag值特征及深部找矿预测

小秦岭地区不同矿化类型的含Au石英脉Au/Ag值有不同的特点，多金属硫化物型一般小于0.8，黄铁矿型介于0.8-2.0之间，少黄铁矿型一般大于2.0。利用Au/Ag值可以大致确定矿脉的矿化类型，判断矿脉的水平，垂向分带和剥蚀深度，预测深部矿脉的矿化类型，东闯金矿床深部Au/Ag值为1.39，预示其深部有可能出现黄铁矿型矿化，深部探矿仍有前景。

The feature of Au/Ag and deep-seated metallogenic prognosis of Dongchuang gold deposit,Xiaoqinling

The Au/Ag of different auriferous quartz veins are different in Xiaoqinling, The Au/Ag in multimetal sulfide type is less than 0.8, in pyrite type is range from 0.8 to 2.0, and in lack pyrite type is more than 2.0. The mineralization type of vein, horizontal and vertical zoning of vein and the denudation depth of vein can be judged by the Au/Ag value, and also can prospecting the mineralization in depth. The Au/Ag value is 1.39 in Dongchuang auriferous deposit of deep-seated, and the pyrite type auriferous quartz veins may be could be found in deep zone, the deep exploration is reliable.
