Abstract
The research area is located on both sides of the regional major fault in Hezuo Minxian Dangchang Jiangluo Town,spanning the central and southern Qinling tectonic belts.The overall direction of the main tectonic lines in the area is NW-SE.The main body is the Xiahe Lixian thrust nappe structural belt,with an overall structure distributed in a northwest direction.Folds and fault structures are well-developed,mainly consisting of tightly closed linear folds.The faults are mainly strike reverse faults,and secondary strike faults and interlayer fracture zones are also well developed.The Yanshan and Hualixi periods have well-developed intermediate acidic magmatic rocks,forming large rock masses,rock bases,and a large number of intermediate acidic rock veins,making them the main ore-forming areas for thermal halo type gold deposits in Gansu Province.关键词
