中文摘要:

Heilangou 金沉积物位于北 QixiaPenglai 金带,它是在三块大金牌之中的在东方山东省(Jiaodong 半岛) 的带。矿石身体在 Guojialing 花岗石以内形成了。在这研究,我们报导黄铁矿,以及 S 的矿物质化学, Pb,并且惊讶 Heilangou 金沉积物的同位素数据。在 Heilangou 金沉积物的黄铁矿的化学作文显示联系金沉积物是典型 magmatic 热水的。形成矿石的材料从外壳被导出的黄铁矿表演的 geochemical 签名和晶体结构。从 Heilangou 表演的黄铁矿的 S 同位素数据从 5.5 ~ 7.8 的一个全面范围和 6.7 的一般水准。在这沉积物的 S 同位素数据类似于从在 Jiaodong 金带的沉积物的那些。Pb 和 S 同位素变化在 Heilangou 金沉积物是小的。206Pb/204Pb, 207Pb/204Pb 和 208Pb/204Pb 比率分别地是 17.465317.5958, 15.510515.5746 和 38.074938.4361。在更低的外壳和 orogenic 带之间的这些数据阴谋。在 Heilangou 金沉积物的 Pb 同位素数据类似于在 Linglong 金沉积物的那些。从 Qixia 金区域(Liukou 和 Majiayao 金牌存款) 系上带子到到 ZhaoYe 金牌的 MupingRushan 金带(Rushan 金存款)(Linglong, Sanshandao 和 Jiaojia 金存款) , 206Pb/204Pb 比率日益增多地增加。从石英获得的同位素数据分开建议形成矿石的液体类似于 magmatic 和大气的水的混合物。这些结果建议形成矿石的元素主要从从更低的外壳导出的来源液体。

英文摘要:

The Heilangou gold deposit is located in the northern QixiaePenglai gold belt, which is one amongst the three large gold belts in the eastern Shandong Province (Jiaodong Peninsula). The ore body has formed within the Guojialing granite. In this study, we report the mineral chemistry of pyrite, as well as the S, Pb, and HeO isotope data of the Heilangou gold deposit. The chemical composition of pyrite in the Heilangou gold deposit indicates that the associated gold deposit is a typical magmatic hydrothermal one. The geochemical signatures and crystal structure of pyrite show that the ore-forming materials have been derived from the crust. The S isotope data of the pyrites from Heilangou show an overall range from 5.5 to 7.8&and an average of 6.7&. The S isotope data in this deposit are similar to those from the deposits in the Jiaodong gold belt. The Pb and S isotope variations are small in the Heilangou gold deposit. The 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb ratios are 17.4653e17.5958, 15.5105e15.5746 and 38.0749e38.4361, respec-tively. These data plot between the lower crust and the orogenic belt. The Pb isotope data in the Heilangou gold deposit are similar to those in the Linglong gold deposit. From the Qixia gold area (the Liukou and Majiayao gold deposits) to the MupingeRushan gold belt (Rushan gold deposit) to the ZhaoeYe gold belt (the Linglong, Sanshandao and Jiaojia gold deposits), the 206Pb/204Pb ratios progressively increase. The DeO isotope data obtained from quartz separates suggest that the ore-forming fluid was similar to a mixture of magmatic and meteoric waters. These results suggest that the ore-forming elements were primarily from source fluids derived from the lower crust.
