东天山系指新疆哈密以东至甘肃、新疆交界处的星星峡一带。在这一地区,以往从未报道过有燕山期岩浆活动的存在。自1977年开始,中国科学院西北富铁科研小分队和新疆冶金地质704队合作,对东天山进行了综合考察研究。经四年多的野外及室内工作结果,根据有关资料,认为在东天山存在有燕山期的岩浆活动,从而为本区的基础地质研究和找矿提供了新
East Tianshan refers to the east of Hami, Xinjiang to Gansu, Xinjiang Xing Xingxia junction area. In this area, there has never been reported the existence of the Yanshanian magmatic activity in the past. Since 1977, Chinese Academy of Sciences Northwest Railway Research Team and the Xinjiang Metallurgical Geological 704 team cooperation on the East Tianshan conducted a comprehensive study. After more than four years of field and indoor work results, according to the relevant data, it is considered that there is a Yanshanian magmatic activity in the East Tianshan Mountains, thus providing new basic geological research and ore prospecting in this area
