运用电子探针系统地分析了西南三江地区金沙江—红河富碱侵入岩带内8个与铜、金成矿密切相关的以及不含矿的喜山期富碱侵入岩中含水矿物磷灰石的成分。结果表明,岩体岩浆期磷灰石显示出富F而贫Cl、SO3、OH的特征,这种特点与环太平洋成矿带类似岩体磷灰石中所表现出来的有一定差异,体现了大陆环境斑岩铜金矿床岩浆挥发分的特殊性。
The electronic probe was used to systematically analyze the eight apatite-bearing water-related minerals in the Jinshajiang-Honghe alkali-alkali intrusive belt in the southwestern Sanjiang region that are closely related to copper and gold mineralization and non-ore-bearing Himalayan alkali-rich intrusive rocks ingredient. The results show that the apatites in the magmatism stage show the characteristics of enrichment of F and depletion of Cl, SO3 and OH, which is different from that of the apatite similar to the metallogenic belt in the Pacific Rim. Specificity of magma volatile matter in continental environment porphyry copper - gold deposit.
