长山斑岩型钼多金属矿床(点)处于东昆仑地区,矿区内岩浆岩分布较广,岩石组合复杂,主要含矿岩体为斜长花岗斑岩、钾长花岗斑岩、花岗闪长岩、二长花岗斑岩及闪长岩,成矿时代为印支期。钼矿体数量较多,规模较小,虽发现较多斑岩矿化信息,却未能在区内发现较大规模的斑岩型矿产,但不能排除斑岩体在深部存在的可能。文章在尝试分析成矿背景、含矿岩体特征和原生晕特征的基础上,结合原生晕应用解决的问题探讨重点关 The Changshan porphyry-molybdenum polymetallic deposit (point) is located in the East Kunlun area. The magmatic rocks in the mining area are widely distributed and the rock assemblages are complex. The main ore-bearing rock masses are plagiogranite porphyry, potash-bearing granite porphyry, Granodiorite, monzonitic granite porphyry and diorite, the Indosinian period. Molybdenum ore bodies are large in number and small in size. Although more information on porphyry mineralization is found, large-scale porphyry-type minerals can not be found in the area, but the possibility of the presence of porphyry bodies in the deep can not be ruled out. Based on the analysis of metallogenetic background, the features of ore-bearing rock mass and the primary halo, the paper discusses the key points
