摘要: 本文基于包裹体类型、均一温度、盐度、压力、包裹体成分及氢氧同位素的研究,认为下营坊金矿床具有典型斑岩型矿床的特征,成矿流体主要来源于壳幔混熔岩浆,主成矿期有少量大气降水加入。沸腾包裹体群、含子晶的多相包裹体和富含CO2的包裹体可指示富矿地段。均一温度等值线的三维空间变化可以确定富矿地段及矿体产状。

Abstract: Based on the study of inclusion typehomogenization temperature salinity pressure inclu sion composition and H.O isotopes, the authors consider that Xiayingfang gold deposit is characterized by typical porphyry-type deposit, Ore-forming fluid, which was mixed with a little of meteoric water in main metallogenic stage, mainly came from crust-mantle mis-melting magma. The rich ore district can be indicated by boiling inclusion group multifalies inclusion with daughter crystal and inclusion with richful CO2. Three dimensional space variety of homogenization temperature contour line can determain rich ore area and orebody occurence.
