麻栗坡祖母绿产于老君山变质核杂岩内。作者对产于伟晶岩脉中祖母绿的流体包裹体进行了岩相学、显微测温和激光拉曼探针研究。研究表明,与成矿有关的流体为中-高温、低盐度的NaCl-H_2O-CO_2-CH_4±N_2体系。两相H_2O-NaCl型包裹体与H_2O-NaCl-CO_2型包裹体密切共生,两者均一温度范围较一致且后者盐度相对较低。麻栗坡祖母绿包裹体特征表明,流体不混溶作用是麻栗坡祖母绿矿物形成的主要机制。麻栗坡祖母绿矿床的形成与侵入岩有关。
Malipo emerald produced Laojunshan metamorphic core complex. The authors conducted petrography, microscopic temperature measurement, and laser Raman probe studies of fluid inclusions in eclogites from the pegmatites. The results show that the ore-forming fluid is medium-high temperature and low-salinity NaCl-H 2 O-CO 2-CH 4 ± N 2 system. The two-phase H_2O-NaCl inclusions are closely intergrowth with the H_2O-NaCl-CO_2 inclusions, and the homogenization temperature ranges of both are consistent and the salinities of the latter are relatively low. The characteristics of Malipo emerald inclusions show that fluid immiscibility is the main mechanism of Malipo emerald mineral formation. The formation of Malipo emerald deposit is related to intrusive rocks.
