摘要
散岔金矿位于秦祁昆造山带,阿尔金弧盆系,中秦岭陆缘盆地东段,元龙向形、李子园背形反"S"型构造的南段。金矿体呈不规则脉状产出,主要赋存于区内的次级构造断裂带内的含金石英脉,属于岩浆期后热液充填交代型金矿床;矿石主要为石英脉型矿石与蚀变岩型矿石相伴产出特征。该矿床的发现对天水李子园地区寻找同类型矿床具有一定指导意义。
The Sancha gold deposit is located in the Qinqikun orogenic belt, the Altun arc basin system, the eastern part of the continental margin basin of the Middle Qinling Mountains, and the southern part of the Yuanlong and Liziyuan anticlinal inverted ＂S＂ structures. Gold ore bodies occur in irregular veins and mainly occur in gold-bearing quartz veins in the secondary structural faults in the area, which belong to post-magmatic hydrothermal filling metasomatic gold deposits. The discovery of this deposit is of guiding significance for finding similar deposits in the Li Zi Yuan area of Tianshui.
