南天山库勒湖蛇绿混杂岩岩石地球化学特征及其构造背景

THE PETROCHEMISTRY CHARACTERISTICS AND THE TECTONIC SETTING OF THE KULEHU OPHIOLITE MELANGE IN THE SOUTHERN TIANSHAN

通过对南天山独─库公路剖面、黑英山剖面出露的肢解蛇绿岩套各成员的岩石化学、微量元素、稀土元素地球化学等多方面研究，结合区域构造分析，表明该蛇绿混杂岩的构造背景为古生代弧后盆地。

After observing the Heyinshan and Du-Ku highway sections, we studied the petrology,petrochemistry of the ophiolite rocks and combined with the regional geological data. The tectonic setting of the ophiolite rocks belong to backarc basin during early Paleozoic period.
