摘要
新疆东部基性超基性岩常成群成带分布,明显受区域性深大断裂控制,可分为蛇绿岩套型和岩浆侵入型两种.前者包括阿尔曼太岩带和克拉美丽岩带,是蛇绿岩套的主要组成部分;后者包括喀拉通克岩带和黄山岩带,为来源于上地幔的原始岩浆经分异、结晶而成.文中对这两类基性超基性岩的地质地球化学特征进行了系统研究.
The basic-ultrabasic roeks in the eastern Xinjiang are often in a zonal distribution and remartably controlled by the regional deep and large fracture zones. They can be divided into two types: ophiolite suite type and the magma instrusive type. The former includes Aermeta and Kela-maili rock zones,and are the main part of the ophiolite suite. The latter includes Kalatongke and Huangshan rock zones and their primary magma come from the upper mantle. The geological-geo-chemical characterisic of the basic-ultrabasic rocks are systematically studied in this paper.
