研究区大地构造位置处于秦岭褶皱系北大巴山加里东褶皱带蒿坪-老县复向斜的北翼,出露的地层是下志留统大贵坪组和梅子垭组。区内断裂构造、褶皱构造发育,大贵坪组二段(Sd~2)为区内重要的含金层位。通过对该区金矿地质特征的研究分析,认为黑云母变斑晶绢云母石英片岩与泥质变砂岩互层是重要含金层位。
The tectonic location of the study area is located in the north wing of the Artemisia-Laoxian synclinorium in the Caledonian fold belt of the North Dabashan in the Qinling fold system. The exposed strata are the Dachangping Formation and the Meiziya Formation of the Lower Silurian. The fault structure and fold structure developed in the area. The second member of Daguiping Formation (Sd ~ 2) is an important gold bearing layer in the area. Through the study and analysis of the geological characteristics of the gold deposits in this area, it is considered that the interbedded layers of biotite schistite serpentinite and argillaceous sandstone are important gold-bearing beds.
