研究区属西秦岭多金属成矿带,位于关子镇—李子园新元古—晚古生代裂陷火山—沉积带中,处于连接祁连与北秦岭造山带巨大的反“S”型构造东南部。区内出露岩性主要为震旦—奥陶系李子园群地层,其走向为NE—NEE;区内构造主要为断裂构造,走向多为NE—NEE,南倾。通过野外调查,在研究区发现了多片金异常晕和金矿化点,并初步分析研究了成矿的地质背景与地质特征,总结了该区的找矿标志,为进一步探矿工作提供依据。
The study area belongs to the West Qinling polymetallic metallogenic belt. It is located in the Guanzi-Ligeyuan Neoproterozoic-Late Paleozoic rift-volcanic-sedimentary belt, and is located in a huge anti-S-shaped structure connecting the Qilian and North Qinling orogenic belts Southeast. The main lithology in the area is the stratum of the Liziyuan Group of the Aurora-Ordovician, with NE-NEE trending toward the NE-NEE. The structural features of the area are mostly of fault structure, mostly NE-NEE and southward. Through the field investigation, multiple anomalous halo and gold mineralization sites were found in the study area. The geological background and geological characteristics of the ore-forming were analyzed and the ore-prospecting signs of the area were summarized, providing the basis for further prospecting.
