中国陆相次火山岩型铜银矿床分布广泛 ,银矿与酸性岩有关 ,铜矿与次英安玢岩有关。形成时代为燕山早、晚期。石英的δ18O值在 +7.9‰～ +16 .3‰之间 ,δ18OH2 O值在 - 3.0‰～ +8.1‰之间 ,δD在 - 5 5‰～ - 10 6‰之间。硫化物的δ3 4 S值在 - 9.8‰～ +9.6‰之间 ,硫化物的硫同位素富集顺序为δ3 4 SPy>δ3 4 SSp>δ3 4 SGn>δ3 4 SPo,硫化物矿物对平衡温度在 16 0～4 0 0℃ ,大多数溶液的硫同位素平均组成 (δ3 4 SΣS)为 +2‰～ +5‰ ,个别为 +2 0‰。
The terrestrial volcanic-type copper-silver deposits in China are widely distributed. Silver deposits are related to acidic rocks, and copper deposits are related to secondary ore deposits. The formation of the early Yanshan, late. The δ18O value of quartz is between +7.9 ‰ and +16 .3 ‰, δ18OH2 O is between -3.0 ‰ and +8.1 ‰, and δD is between -5.5 ‰ and -106 ‰. The δ3 4 S values of sulfides range from 9.8 ‰ to + 9.6 ‰, and the sulfur isotope enrichment order of sulfides is δ3 4 SPy> δ3 4 SSp> δ3 4 SGn> δ3 4 SPo. The average composition of sulfur isotopes (δ3 4 SΣS) of most solutions ranged from + 2 ‰ to + 5 ‰ at 16 0-400 ° C, with +20 ‰ on average.
