摘要
Recent years, Huashigou copper deposit in the western Gansu Province is the most evaluate copper deposits. It’s orebodies mainly occur in the late Hercynian Tonalitic rocks and Tonalite porphyry. Ore-bearing rock and the spread of the stratigraphic is controlled by the arc faults nearly south-north. The mineralization were positively correlated with silicification, phyllic alteration, biotite alteration and have the characteristic of porphyry type deposits alteration zonation. The direct prospecting criteria are secondary oxidation zone, silicification, phyllic alteration arc tectonic belt at surface layer as well as the combination of the ore-bearing rock.
