摘要
粤北大宝山多金属矿床位于曲仁盆地南侧,大东山—贵东东西向构造带与雪山嶂北北东向隆起带的复合部位。本文拟据大宝山矿床包裹体温压地球化学特征和氢、氧同位素以及矿物流体包裹体Rb-Sr等时线年龄的系统研究,认为成矿物质主要来源于岩浆期后含矿热液,其成因应属于燕山早期岩浆期后热液矿床。
Dabao Shan ore deposit is situated at the Qujiang county, Guangdong Province. It is presently main one of polymetallic mineral bases in Southern China. The paper deals mainly with temperature-pressure geochemistry characteristics, hydrogen and oxygen isotope composition as well as the Rb-Sr isochron ages of fluid inclusions in mass of rock and orebody in the Dabao Shan polymetallic deposit.
Characteristics of the fluid inclusions temperature-pressure geochemistry in the Dabao Shan deposit shows that the subdacite porphyry is related closely to Cu-Pb-Zn mineralization.and the granodiorite porphyry is related closely to W-Mo-Bi mineralization.
It leads to that the Dabao Shan Cu-Pb-Zn-W-Mo-Bi deposit are magmatic hydrothermal deposit of two minerogenetic processes during Early Yanshan.
