下扬子和南岭两个地区的华南型块状硫化物矿床在成分上有着显著的差异:前者有用金属以铜为主,铅、锌为次,并可综合利用金、银、钴和钼。矿石中放射性成因铅含量低,δ~(34)S于零值附近呈塔式分布,成矿流体具有高盐度和富钠特征。后者有用金属铅、锌与铜同样重要,并可综合利用银、锑、汞、铀、铋、铊和钼,矿石中放射性成因铅含量高,δ~(34)S呈离散型分布,成矿流体具有低盐度和富钾特征。这些差异主要受沉积盆地基底成分的控制,因而反映了成矿时大陆地壳成熟度的差异。不同成熟度大陆地壳的特征性组分可以通过海底淋滤-喷气、陆源沉积和中生代岩浆-热液的叠加而进入块状硫化物矿石。
There are significant differences in the composition of the southern China massive sulphide deposits in the Lower Yangtze and Nanling areas: the former is mainly composed of copper, while the other is lead and zinc, and the combination of gold, silver, cobalt and molybdenum can be comprehensively used. The lead content of radiogenic radioactive ore is low, δ ~ (34) S is tower distributed around zero value, and ore-forming fluid has high salinity and sodium-rich characteristics. The latter is useful for metallic lead. Zinc is as important as copper and can comprehensively utilize silver, antimony, mercury, uranium, bismuth, thallium and molybdenum. The radioactive lead content in ores is high and δ ~ (34) S is discretely distributed. Ore fluid has low salinity and potassium-rich characteristics. These differences are mainly controlled by the basement composition of the sedimentary basin and thus reflect the difference in the maturity of the continental crust during mineralization. The characteristic components of the continental crust of different maturity can enter the massive sulphide ore through sea floor leaching-jet, terrigenous sedimentation and Mesozoic magma-hydrothermal superposition.
