通过对东昆仑北段祁漫塔格造山带工作和研究,发现并确定了一套中、晚元古代基性—超基性侵入体,据岩石学、岩石化学及同位素地球化学资料表明,该套基性、超基性岩为地幔岩浆活动的产物,反映了古元古代结晶基底形成后,祁漫塔格地区在中元古代—晚元古代早、中期一直处于拉张伸展环境,为祁漫塔格前寒武纪构造岩浆活动提供了新证据。 Based on the work and research of Qimantag orogenic belt in the northern section of Eastern Kunlun, a series of mid- and late-Proterozoic basic-ultrabasic intrusions have been discovered and identified. According to the petrology, petrochemistry and isotopic geochemistry data, The mafic and ultrabasic rocks are the product of mantle magma activity. After the formation of the Paleoproterozoic crystalline basement, the Qimantag area has been in stretching and stretching environment in the middle and early Proterozoic and the Late Proterozoic, Precambrian tectonic magmatism provides new evidence.
