摘要
本文在综合鄂东南地区岩浆岩中矿物包裹体资料的基础上,探讨了岩浆岩中矿物包裹体特征、分布等与区域矿产分布间的关系;探讨了具有不同成矿专属性的岩浆岩始晶温度、气液温度、气液比、含盐度、成岩压力及形态等方面的变化特征及其与矿化富集之间的关系;初步探讨了成岩的氧逸度条件。
Based on the comprehensive materials of mineral inclusions within mag- matites from southeastern Hubei area,this paper researches into thc rela- tionship of the characteristics and distribution of mineral inclusions within magmatites to the regional distribution of mineral resources;re- searches into the variation characteristics of initial crystallization tem- perature,pneumatolyto-hydrothermal (pneumatolitic solution) temperature, ratio of gas to fluid,saltness,diagenetic (petrogenic) pressure,mor- phology,etc.of the magmatites possessed of various minerogenic speciali- zations,and the relationship of these characteristics to the mineraliza- tion enrichment;preliminarily researches into the condition of oxygen fugacity for (to) diagenesis,and the utilizations of mineral inclusions within magmatites for prognosticating mineral resources and for reconnais- sance and prospecting.
