Abstract

Taking Huanglong, Changgou and Jindoupo gold ore areas located in Northern Hanyin ore field, Southern Qinling as the typical study area, through the large-scale tectonic lithofacies mapping, measuring geologic section and complex map compilation, the ore-controlling factors of this ore-field has eventually been acquired which would provide the directions of gold exploration based on previous research results. Comprehensive analysis shows that gold mineralization of this field is bound up with Silurian Meiziya Group stratum, and the brittle-plastic shear zone restricts the spatial distribution of gold deposits, and the locations of the ore bodies are decided by the secondary faults. S₂ structural foliation obviously controls the gold mineralization, and the thermometamorphism which develops biotite and garnet porphyroblasts can cause the gold element to reactivate. And in the late stage it is the retrograde metamorphism period during which the temperature is very available for the form of gold deposits. Therefore the gold exploration in this area should be focus on the brittle-plastic shear zones in the future, especially the positions of those connection of different rock layer, the region near the secondary faults, and the scopes where biotite and garnet porphyroblasts massively appear. Meanwhile the direction of gold seeking should follow the main spatial distribution direction of S₂ foliation.
