GEOLOGICAL CHARACTERISTICS OF MIAOGOU SILVER-LEAD-ZINC-RICH DEPOSIT IN LIAONING PROVINCE

The Miaogou Ag-Pb-Zn-rich deposit occurs in Paleoproterozoic Gaojiayu formation in the north limb of Hupiyu overturned fold. A gabbro rock body intruded the formation along a north-trending fault, with ore-forming matters extracted from the underlying Dashiqiao formation, forming one orebody and four mineralized bodies in the previously existed bedding fracture belt. The deposit has not attracted enough attention for its small scale and short discovering history. However, due to its special metallogenic model, a further study on such type of deposit is significant for both metallogenic theory and ore-searching practice in the area.
