Abstract
The Longweigou porphyry copper deposit in Qinghai Province is an important deposit discovered in southern Altun Mountains in recent years.It has been proved that the Cu(Au) ore bodies are directly related to the granite-porphyry veins.Based on geological and geochemical background,this paper has discussed the relationship between the porphyry veins and the ore-forming process,and put forward the metallogenic mechanism of this porphyry Cu(Au) deposit.
