宏远(铜)钼矿和吐克吐克钼铜矿为新疆西准噶尔地区新发现的斑岩型矿床。流体包裹体测温和激光拉曼探针分析研究表明,宏远(铜)钼矿发育气液、气体和含子矿物包裹体等3类包裹体,气液比变化大,均一温度集中在140℃~200℃和260℃~340℃两个区间;吐克吐克钼铜矿只含有气液和含子矿物两类包裹体,气液比变化小,均一温度集中在180℃~220℃。两个矿区均发育高盐度和低盐度的NaCl-H_2O-CH_4-CO_2流体,显示含甲烷还原性流体的性质。宏远(铜)钼矿辉钼矿Re-Os同位素分析表明其成矿年龄为314.3±1.9 Ma,与西准噶尔包古图斑岩铜矿成矿时代一致。
The Hongyuan (copper) molybdenum ore and the Tuoktok molybdenum-copper mine are newly discovered porphyry deposits in western Junggar region, Xinjiang. Fluid inclusions temperature measurement and laser Raman probe analysis showed that the gas and liquid inclusions in Hongyuan (Cu) molybdenum mine developed three types of inclusions, gas-liquid ratio changes, the homogenization temperature concentrated in 140 ℃ ~ 200 ℃ and 260 ℃ ~ 340 ℃. There are only two types of inclusions, ie, gas-liquid and ore-bearing minerals. The gas-liquid ratio changes little, and the homogenization temperature is 180 ℃ ~ 220 ℃. High-salinity and low salinity NaCl-H 2 O-CH 4 -CO 2 fluids were developed in both mines, indicating the nature of the methane-containing reductive fluids. The Re-Os isotopic analysis of the molybdenite from Hongyuan (Cu) molybdenite shows that the metallogenic age was 314.3 ± 1.9 Ma, which is consistent with the age of the Baogutu porphyry copper deposit in western Junggar.
