Geological Characteristics and Prospecting Direction of the Deneng Copper-Polymetallic Deposit in Coqen County,Tibet,China

The Deneng Copper-polymetallic deposit is discovered with the Longgeer-Cuomian 1:50 000 minerals survey.There are six bodies of copper ore achieving production-grade with useful components such as Pb,Zn,Au and Ag etc.With good ore-forming geological condition,ore bodies mainly occur in outside of the contact zone and tectonic fracture zone.Cu4 ore body is the largest one.Basing on deep drilling and surface trenching data,the variation coefficient of ore grade and thickness along the ore strike and tendency is small.This copper polymetallic deposit belongs to the structural-altered-rock type.The formation is closely related to the magmatic activity.Spatial distribution is controlled by magmatic and fracture.Induced polarization anomalies and geochemical anomalies show that this deposit area is the prospecting favorable place of the copper,lead and zinc polymetallic deposit.
