Geological Characteristics and Prospecting Significance of the Yuelianggou Silver Polymetallic Deposit in Luoning County,Henan Province

The Yuelianggou silver polymetallic deposit is located in the Ag-Au-Cu-Pb-Zn polymetallic ore belt,Xiongershan Mountains,Hua-xiong platform margin depression.. The orebodies occur in the Archean Taihua group Caogou and Shibangou Formations,and display veined and lenticular textures, with few irregular bedded textures. This paper presents the studies of regional metallogenic background,geological,geophysical and geochemical characteristics and metallogenic geological conditions of this deposit,and its metallogenic prospecting and prospecting significance. The result shows that the Taihua and Xionger groups metamorphic core complex and detachment faults at the contact site comprise the basic structural framework in the region. These structures exert a key control on the metal deposits,and the dome contact site between the Taihua Group and Xionger group is favorable for ore searching. It is thus inferred that doing research work in the areas of the detachment fault-metamorphic core complex will provide guidance significance for searching for similar deposits.
