西藏白朗县南闪长岩地球化学、同位素年代学特征及其构造意义
Geochemistry, isotopic chronology and tectonic significance of diorite in the South of Bailang County, Tibet
摘要
Abstract
In this paper, petrology, geochemical characteristics and U-Pb isotope chronology were comprehensively investigated to analyze the geological features of the intermediate intrusive rocks discovered in the south of Bailang County, Tibet. The results show that these rocks belong to calc-alkaline rock series, with LREE enrichment and HREE depletion;they have geochemical characteris⁃tics of intraplate basalts, being mafic intrusive body formed at the Himalayan passive continental margin stretching-compression stage in the late Triassic period. The results obtained by the authors provide new magmatic evidence for Early Tethys passive margin sedi⁃mentary basin evolution of the Yarlung Zangbo River.关键词
