| 摘 要： | 新疆萨喀尔得铜矿属中低温热液型，该矿石英和方解石样品中^δ13CPDB值为-17．3‰— -0．7％，δ^18OSMOW为16．2‰-22．4‰ δ18OH2O 水值为6.9‰-12.5‰水值为6．9‰-12．5‰，8D变化于-73．8‰—-52．4‰之间。研究表明，成矿流体主要来源于深部发生循环加热的建造水，并混合变质水和岩浆水；成矿早期流体中的C主要来源于地层水或大气降水，晚期有深部岩浆水的加入。^δ^34S值变化范围为0．2‰-6．1％o，表明流体中的S主要来自岩浆或上地幔。

| Abstract: | The Sakaerde copper deposit is a mesothermal-epithermal deposit. The 8 I~CPDB values of quartz and calcite samples in the deposit vary in a narrow range of- 17.3%0~-0.7%0. The ~ ~8OsMow values range from 16.2‰ to 22.4‰, their corresponding ^18OH1O values are between 6.9%0 and 12.5‰, and the 8 D values of fluid inclusions vary from -73.8‰ to -52.4‰. These data imply that the ore-forming fluids of the ore deposit were mainly derived from the heated formation water mixed with a small amount of magmatic water and metamorphic water. The carbon in ore-forming fluids mainly came from formation water or atmosphere precipi- tation, with the addition of some deep magmatic water at the late stage. The δ^34S values range from 0.2‰to 6.1‰, implying that the sulfur in ore fluids mainly came from the magma or the upper mantle. |
