摘要
山门银矿的成矿热液体系中总硫同位素组成近于陨硫值与岩浆硫值相近,具深源硫特点。金属矿物硫同位素组成在同位素交换平衡条件下属中低温环境沉淀。同位素变异时间、空间上都有较明显的演化规律。
The components of total sulfur isotopes in the ore-forming hydrothermal system of the Shanmen Ag deposit are similar to the value of meteoritic sulfur and much the same as the value of magmatic sulfur with the characteristics of deep source sulfur. The S isotopic components of metal minerals indicates a mid-low-temperature environmental precipitation under the condition of isotopic exchange equilibrium. The isotopic variation also indicates a more obvious evolutional regularity in time and space.
