由于各构造背景下岩浆混合的表现和标志不同，可以为研究大地构造背景提供依据。本研究通过对恰哇尔岩体中包体的形态、产状及特征，特别是包体的结构、矿物成分及矿物生长习性等岩相学特征的分析，初步确定恰哇尔岩体岩浆由酸性、基性两种不同成分的岩浆在未完全结晶状态下相互混合形成，提出该岩体具岩浆混合成因花岗岩，对中南祁连中生代以来的地壳岩化过程以及壳幔岩浆的相互作用研究提供了理论依据。

Performance and symbol of magma mixing of various tectonic background is different , which can provide evidence for the study of tectonic settings .The petrographic characteristics of in-clusion in Qiawaer rock mass , such as rockform , occurrence and feature , especially the structure , mineral composition and mineral growth were analyzed .The initial Qiawaer rock mass generated from mixing of uncrystallized acidic and mafic magma .The rock mass is magma mixing granite gene-sis.The conclusion provides a theoretical basis for studying the south central Qilian since the Meso-zoic crustal rocks and crust mantle magma interaction .
