Outcrop characteristics, formation mechanism andmineralization of thrust nappe structure in northwest Fujian Guanling area

The lower part of Guanling belongs to guanling village, Shanxia Town, Pucheng County, Fujian Province. Geologically, the southeastern margin of huazhukeng volcanic basin in Chongan Pucheng area has strong tectonomagmatic activity, especially in the late Jurassic volcanic activity, forming the main ore bearing rock acid volcanic rock for uranium and molybdenum polymetallic mineralization. The lower Guanling fault is a NE trending tectonomagmatic active belt. It is also a large thrust nappe structure, which controls rock, basin and ore in the early stage. At present, good industrial uranium ore bodies and a large number of anomalies have been found in the volcanic rocks at the footwall of the structural belt. It is predicted that there is a deep prospecting space and there may be rich ore bodies.
