Metallogenic Systems and Regularity of Porphyry-Type Molybdenum Deposit in Dabieshan Mountain

Dabieshan Mountain orogen consisted of the south-east Qinling fold Zone,controls the magmatic rock together in southern Henan Province with Guishan-Meishan fault zone and north-east fault.Neutro-acid batholith of Yanshan stage is the parent rock of small metallogenetic rock which is the metallogenetic parent rock of porphyry-type molybdenum deposit.During the continent,after pushing and stretching lithosphere becomes thinner,which makes the asthenosphere and mantle rise and finally the granite with deep origin but superficial layer comes into being.The ore type is related to the composition of magma,and clearly indicates the metallogenetic property.The metallogenetic series of porphyry-type molybdenum deposit is formed with the same constitution and magma metallogentic effect,but different space position.It will be significance for the exploration of molybdenum,copper,lead and zinc in Dabieshan Mountain to research on the metallogenetic rules of porphyry-type molybdenum deposit according to the metallogenic systems.
