报道产于兰坪-思茅盆地中侏罗系沉积砂岩、泥岩中的金满低温热液脉状铜矿床中含Cu硫化物的Cu同位素组成, 发现其δ65Cu值较低, 变化范围为-3.70‰ ～ 0.30‰, 明显不同于高温岩浆热液铜矿床(δ65Cu值为-0.62‰ ～ 0.40‰)和大洋底块状硫化物矿床(δ65Cu值为-0.48‰ ～ 1.15‰). 根据研究结果认为: 较低的成矿温度、不同的成矿物质来源、不同的成矿阶段和有机质参入成矿等因素, 可能是造成金满型低温热液脉状铜矿床Cu同位素分馏的原因.
The Cu isotopic compositions of Cu-bearing sulfides in the Meso-Jurassic sedimentary sandstone and mudstone in the Lanping-Simao Basin are reported, and the δ65Cu values are found to be low, ranging from -3.70 ‰ ~ 0.30 ‰, which is obviously different from the high-temperature magmatic hydrothermal copper deposit (δ65Cu = -0.62 ‰ ~ 0.40 ‰) and the oceanic massive sulphide deposit (δ65Cu = -0.48 ‰ ~ 1.15 ‰). According to the results : Lower metallogenic temperature, different metallogenic sources, different metallogenic stages and organic matter incorporation may be responsible for the Cu isotopic fractionation of the gold-filled low-temperature hydrothermal vein-type copper deposits.
