Abstract: Based on research of the Tibet Gangjiang porphyry copper-molybdenum deposit composite porphyry body characteristics,mineralization characteristics,ore-forming stages,the relationship between late dykes and mineralization,Gangjiang deposit district initially is divided into six times magma intrusion and three mineralization stages. By analyzing the ore-controlling factors,the paper put forward that mineralization is closely related to tonality and granodiorite veins by controlled NS-trending and NE-trending faults. The tonality and granodiorite veins formation period is the main mineralization stage of Gangjiang deposit.

Key words: Gangjiang copper-molybdenum deposit, porphyry, mineralization stages, ore-controlling factors
