Abstract

Based on features of circular images of MSS, tectonic surroundings, features of veins, surrounding alteration, ore deposit geology and geochemical data, the anthor inferred that the circular feature of the Laochang area resulted from both concealed granites intrusing and hydrothermal solutions uprising. The silver-lead ore deposit is not a volcanic deposit but a mid-hydrothermally polygenetic compound type. It is associated with the concealed granite body and has two types of Ag-Pb-Zn and Au-Cu deposits. According to the prognosis, a new Au-Cu ore deposit had been prospected in the depths of the mining district.
