摘要
在野外填图和室内地球化学研究的基础上，对东昆仑造山带蛇绿岩重新进行了厘定，并对本区构造演化进行了探讨，把东昆仑造山带蛇绿岩划分为４个带，从南到北分别为：阿尼玛卿蛇绿岩带、塔妥蛇绿岩带、清水泉蛇绿岩带、乌妥蛇绿岩带．它们在围岩的时代、构造样式及围岩变质程度、地球化学等方面均存在明显差异．
In this paper, the re_determination of the ophiolitic belts in the Eastern Kunlun orogenic zone is presented on the bases of the field mappings and indoor geochemical research. In addition, the structural evolution of this region is discussed. The ophiolite in the Eastern Kunlun orogenic zone is divided into four parts from the south to the north: Animaqing ophiolitic belt, Tatuo ophiolitic belt, Qingshuiquan ophiolitic belt, and Wutuo ophiolitic belt. Sharp differences among these four belts arise in terms of wall_rock time, structural pattern, wall_rock metamorphism, and geochemistry.
