| 摘 要： | 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。

| Abstract: | Leijiagou gold deposit is located in west Qinling polymetallic metallogenic belt, which is situated within Guanzizhen-Liziyuan Neoproterozoic-Late Paleozoic rift volcanic-sedimentary belt, in the southeast of the huge anti-＂S＂ type structure which connected Qilian with the North Qinling orogenic belt. Outcropping rock are Aurora-Ordovician Liziyuan Group with the direction of NE-NEE. The structures existing in the work area are faults, mostly with direction of NE-NEE and south-dipping. Through field investigation, we found some gold anomalies and mineralization. The paper summarized the geological background and characteristics of mineralization, and points out the prospecting marks in this area. |
