【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ＣＯ＿２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。更多还原

【Abstract】 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 witha 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 vari-ety of homogenization temperature contour line can determain rich ore area and orebody oc-curence. Kdy word inclusion geochemistry gold deposit Xiayingfang of pingquan更多还原
