花岗质岩石作为大陆地壳的重要组成部分是研究大陆地壳生长和演化的有效工具,其携带的包体在探讨壳-幔相互作用和地球深部过程中亦具有重要意义。西坝花岗质岩体是南秦岭印支期花岗质岩带的重要组成部分,岩体中分布有较多的暗色微粒包体,具有明显的岩浆混合特征。本文通过研究寄主岩和包体的岩相学特征及岩体的锆石饱和温度,以期对西坝岩体的源区 Granitic rocks, as an important component of the continental crust, are effective tools for studying the growth and evolution of the continental crust. The inclusions are also of great significance in the study of the crust-mantle interaction and deep earth processes. The Xiba granitic granite is an important part of the Indosinian granitic belt in the South Qinling. There are many dark-color inclusions in the rock mass with obvious magma mixing characteristics. In this paper, by studying the lithofacies characteristics of host rocks and inclusions and zircons saturation temperature of rock mass,
