| 摘 要： | 分析了江苏省主要含矿花岗岩体的主元素、微量元素含量,所含黑云母的成分以及包裹体的类型等地球化学特征.结果表明它们大多属于岩浆花岗岩,且以I型花岗岩为主.成矿元素Cu、Pb、Zn在I型含矿花岗岩中普遍有一定程度的富集,其中以Cu的富集程度最好;Cr、Co、Ni在此类岩体中含量亦较高.广泛发育多种包裹体,尤其是发育含子矿物多相包裹体是含矿花岗岩体的重要特征.指出应加强在宁镇中段某些I型花岗岩体中寻找Cu多金属矿的工作.

| Abstract: | Major and trace elements, biotite composition, and inclusion types of main ore-bearing granitoids in Jiangsu province has been investigated. The results show that the most granitoids are belong to magmatic granites, and dominated by I type granite. Ore-forming elements such as Cu, Pb, and Zn are generally enriched to a certain extent in I type granites, in which Cu is the most. Content of Cr, Co and Ni is comparatively higher in I type granites. Well-developed inclusions, especially the multi-phase inclusions with daughter minerals, are a key feature for ore-bearing granitoids. It is pointed out that Cu polymetallic prospecting should be strengthened in some I type granitoids in the middle parts of Nanjing-Zhengjiang area. |
