江西城门山铜矿床由夕卡岩型矿床、块状硫化物型矿床和斑岩型矿床组成.本文从硫同位素组成角度,为讨论城门山矿床的成因以及上述3种类型矿床之间关系提供一方面的依据.1 矿床及围岩中的硫同位素组成1.1 夕卡岩型矿床的硫同位素组成夕卡岩型矿床的δ~(34)S值(33件)变化范围很窄,为+1‰～+3.4‰,全为正值,均值为+2.4‰.该类型矿床的δ~(34)S值接近于零,样品频数明显呈塔式分布.
Jiangxi Chengmenshan copper deposit consists of skarn deposits, massive sulfide deposits and porphyry deposits.In this paper, from the perspective of the composition of sulfur isotopes, to discuss the genesis of the Chengmenshan deposit and the relationship between the above three types of deposits The relationship provides the basis for the one hand.1 Sulfur Isotopic Compositions in Deposits and Surrounding Rocks 1.1 Sulfur Isotope Compositions of Skarn Deposits The δ ~ (34) S values (33) of the skarn deposits vary very narrowly and are + 1 ‰ ~ + 3.4 ‰, all positive values, with an average value of + 2.4 ‰. The δ ~ (34) S values of this type of deposit are close to zero, and the frequency of samples shows a tower distribution.
