新疆东准噶尔萨尔托海石英二长闪长岩岩体形成时代及构造环境
The formation epoch and tectonic environment of quartz monzonite diorite in Sartokay, east Junggar, Xinjiang
摘要
Abstract
Quartz monzonite diorite in Sartokay of east Junggar belongs to the Paleozoic Ertix tectonic-magmatic belt. Rock geo⁃chemistry shows that quartz monzonite diorite in Sartokay belongs to magnesian grantoid of metaluminous, high-K calc-alkaline se⁃ries, with enrichment of LILE, depletion of HFSE, and concentration of LREE. LREE and HREE fractionating degree is relatively high, and the negative anomaly of Eu is not obvious. The age of 277.4 ±5.1Ma indicates Early Permian after the collision in an intra⁃plate tectonic environment.关键词
