| 摘 要： | 铜官山铜-铁-金-硫矿床发育上部层状矿体和下部网脉状矿体,地球化学特征呈现出明显的垂向变化和二元结构性。从下部网脉状矿化岩石到上部层状矿石,CaO、MgO、Fe2O3、FeO等含量和δ18O值总体逐渐增高,SiO2、Al2O3、TiO2、K2O、Na2O、REE等含量和流体包裹体温度(341.9℃→178.0℃)及δ34S值总体逐渐降低。黄铁矿δ34S值为(+2.1~+7.9)‰,上部层状块状矿石中方解石和石英δ18O平均值为+13.9‰,下部网脉状矿化岩(矿)石中脉石英或全岩δ18O平均值为+11.7‰。

| Abstract: | The geochemical features of the Tongguanshan Cu-Fe-Au-S deposit were presented by a vertical change and a "binary texture", composed of the upper stratiform ore beds and the lower disseminated-veinlet mineralized rocks(ores). The contents of CaO,MgO,Fe2O3 and FeO, and the average value of δ18O increased progressively from the lower disseminated-veinlet mineralized rocks(ores) to the upper stratiform ore beds, accompanied with the contents of SiO2,Al2O3,TiO2,K2O,Na2O and REE, the measured temperatures(from 341.9 ℃ to 178.0 ℃) of fluid inclusions and δ34S values decreasing gradually. The δ34S values of pyrite ranged from +2.1‰ to +7.9‰. The average δ18O value of calcite and quartz in the upper stratiform ore was +13.9‰, and the relevant value of quartz and whole rock in the lower disseminated-veinlet mineralized rocks(ores) being +11.7‰.The geological-geochemical features showed that the Tongguanshan Cu-Fe-Au-S deposit should be of submarine sedimentary exhalative origin. |
