| Abstract: | East Gobi porphyry molybdenum deposit which locates at south of Hami（about 110 km away）,Xinjiang province,is in the Jueluotage polymetallic metallogenic belt of Eastern Tianshan Mt..Three type magmatic rocks,pale red porphyritic granite,granite prophyry vein and fine-grained granite vein are distributed in East Gobi Mo deposit,while ore-bodies are mainly occurred in the outer contact zone of Late Hercynian intruded porphyritic granite and low-metamorphic clastic rock.The petrological and geochemical feature of ore-bearing porphyry in East Gobi Mo deposit is comparison with the porphyry in other porphyry-type Mo deposits,which indicated that the porphyritic granite is with higher SiO2 content and belongs to calc alkali S-type granite.East Gobi porphyry Mo deposit is the first discovered super-large Mo deposit in Xinjiang province,this research may be very valuable for prospecting the similar deposit in this area. |
