Abstract

Lunlang lead-zinc deposit located in central Lhasa-Linzhou-Mozhugongka Pb-Zn metallogenic region,belong to north part of Brahmaputra giant copper polymetallic metallogenic belt.About 10 gravity anomaly areas and 18 magnetic anomaly areas are found in geophysical surveys at Lunlang lead-zinc deposit.Through integrated evaluation of those gravity and magnetic anomalies we find that a clear corresponded relationship between 5 magnetic and gravity anomaly areas,and these anomaly areas are related to mineral deposit,which have great prospecting potential.This research also indicated that high magnetic anomaly zone,local gravity and magnetic anomalies junction areas,and high gravity and magnetic anomaly areas are all the favorable prospecting area.
