摘要
柿竹园钨锡钼铋多金属矿床矿物的硫同位素组成大致呈塔式分布。矿物共生组合、(?)体包裹体资料及化存平衡计算的结果表明、流体(包括岩浆流体和成矿流体)中含硫组分以H_2S为主,流体的(?),而(?)矿石的硫主要来自千里山花岗岩浆,但成矿期后黄铁矿的部分硫来自地层。
The sulfur isotope composition of minerals in the deposit is distributed approximately in a tower shape. The paragenetic association of minerals, data of fluid inclusions and the acounting results of chemical equilibrium indicate that sulfur-hearing composition is mainly H2S in fluids, including magma fluid and mineralization fluid. The δ34 SH2s in fluid is 3.0-5.5‰, and δ34S mineralization fluid = δ34S magma fluid = δ34S magma = 5.0‰. The sulfur in the ores is mainly from Qianlishan granite, and some sulfur in pyrite after mineralization are from the strata.
