As a whole, the rocks from diorite enclaves, through quartz-diorite, granodiorite to monzonitic granite, have the feature of REE slightly increasing, Eu from weakly positive transits to negative anomaly, but the diorite enclaves which has Eu negative anomaly. Besides, the Ba, Nb, Ta, P and Ti all show negative anomaly, and have positive anomalies of K and Th, simultaneously, there exists Sr positive anomaly in some rocks. Along with the increasing of the SiO〓, the P and Ti have negative anomaly, Th and K positive anomaly are obvious.

These suggest that the xenocrysts were captured by the enclave magma from the host magma. On diagram of total alkali vs. SiO〓(Middlemost, 1994), most samples of the host rocks plot within the area of diorite, the samples of the quenched margin plot within the area of gabbro-diorite and the samples of the enclave plot within the area of diorite.
