摘　　要：新疆面积约为1.6×10~6 km^2,是重要的固体与能源矿产聚集地,但因各地质科学领域研究侧重点不同,对矿产资源的主要约束认识也存在差异。通过综合分析新疆地质矿产及准噶尔、塔里木盆地、天山造山带岩浆岩、构造、地球物理、地球化学、石油、煤炭、地震及铀矿地质等信息,以钼矿为例,说明石炭纪准噶尔亚幔柱与二叠纪塔里木亚幔柱对新疆内生金属矿产及准噶尔、塔里木2个盆地内能源矿产等的约束作用。明确提出了两个盆地内具有良好固体矿产成矿潜力,并初步探讨了在准噶尔、塔里木两盆地内进行金属矿产深部找矿的意义。Xinjiang covers an area of about 1.6 ×106km2 , where serves as an important gathering place of solid and energy minerals. But the focus of geosciences research are different, their un derstanding for the constraints on mineral resources are also differences. In this paper, various geological data has been comprehensively analyzed, including the geology and mineral resources in Xinjiang, as well as the magmatic rock, tectonics, geophysics, geochemical, oil, coal, earth quake and uranium geology of Junggar basin, Tarim basin and Tianshan orogenic belt. Taking the molybdenum deposit as an example, the constraints of Carboniferous Junggar sub mantle plume and Permian Tarim sub mantle plume on the endogenous metal mineral in Xinjiang and the energy minerals in Junggar and Tarim basins have been illustrated and discussed. It＇s put for ward that these two basins have good potential of mineral mineralization. Finally, the significance of deep mineral prospecting in the Junggar and Tarim basins has been discussed in this paper.
