Qiagong skarn iron (copper) deposit is located in Xietongmen County of Tibet, China (N 2952'14.9, E 8824'10.3). It is situated at the middle-western Gangdese porphyry copper-belt. Mineralisation is related to a Himalayan porphyry intrusion, with the mineralised body occurring at the contact zone between the Tertiary Takena Formation carbonate rocks and Himalayan monzonitic granite porphyry. The melt, melt-fluid and fluid inclusions were observed in early quartz, with most abundant fluid inclusions in quartz, calcite and garnet from the skarn. The geology and inclusion assemblage show a close relationship between iron (copper) mineralisation and a Himalayan porphyry intrusion. Based on preliminary inclusion studies, this paper discussed the characteristics, evolution of ore-forming fluid and affiliation to the Himalayan porphyry intrusion._x000D_
