中文摘要：
夏尔莆岩体寄主岩石为闪长岩一花岗闪长岩．二长花岗岩组合，其中镁铁质微粒包体十分发育．包体个体大小悬殊，多密集成群、成带状分布，具明显塑性变形特征．包体与寄主岩石或界线截然或渐变过渡．包体中发育斜长石异常环带、针状磷灰石和来自寄主岩石中的长石捕虏晶，包体中不平衡矿物间的共生现象普遍．岩相学特征表明为基性岩浆和酸性岩浆经岩浆混合作用而成．这一新认识为探讨夏尔莆岩体及达尔布特花岗岩带成因提供新佐证．
英文摘要：
The host rock of Xiaerpu granite are composed of the diorite-granodiorite-monzonitic granite.The mafic microgranular enclaves are well developed in the plutons.They are highly varied in size,many distributed in swarms and in zonations which shows the character of strong plastic distortion.They have clear boundary or transitional relationships with host rocks）the abnormal zoning of plagioclase,the acicular apatite,the disequilibrium mineral symbiosis,and the capture feldspar phenocrysts （capture crystal）,are developed in them.These features show that the enclave are produced by the mixing and mingling of basic magma and acid magma.The new cognition provides a new proof for studing the cause of formation of Xiaerpu granite and the granites belt along Darabut tectonic.
