Abstract The Hongshilazi gold-silver orefield in Liaoning Province is tectonically located on the east margin of the Yixian Mesozoic fault basin, Western Liaoning syneclise. The typomorphic characteristics of Au-Ag minerals in the deposit are studied on the morphology of Au-Ag mineral, fineness of Au minerals and microelements, which are significant for the genesis discussion of the deposit. The result shows that the Au mineral is dominated by electrum, occurring betweencrystals, in cracks and inclusions. The fineness of gold ranges from 334 to 813, in average of 664. The microelements of Bi, Cu and Sb are relatively high in the content. The typomorphic characteristics suggest the origin of epi-mesotheo-morphic Au-Ag deposit.
