阿尔泰造山带南缘镁铁质岩体的地球化学特征及铜镍硫化物型矿床找矿前景

Geochemistry of mafic intrusions on the south margin of the Altay orogenic belt and Cu-Ni sulfide ore potential of these intrusions

摘要: 对阿尔泰造山带南缘锡泊渡、阿拉托别和托斯巴斯陶等镁铁质岩体的主量元素和微量元素地球化学特征进行研究,并与喀拉通克岩体进行了对比。结果表明,这些岩体的形成过程与喀拉通克岩体不同,进而评价了这些岩体的找矿前景,提出锡泊渡北岩体具有较好的成矿条件,其他几个岩体成矿条件不十分理想。

Abstract: Major element and trace element geological characteristics of tens of mafic intrusions such as Xibodu, Alatuobie and Tuosibasitao intrusions on the south margin of the Altay orogenic belt were studied and compared with those of the Kalatongke complexes. T
