In this paper, we present the occurrence and mineral components of the enclaves firstly dis-covered in the Cenozoic Pulu volcanic rocks in west Kunlun Mountains, and propose that the enclave is accumulated by fractional crystallization within high-level magma chamber.In addition, the chemical compostions of its primary magma are calculated.The calculated compositions are similar to those of the Kangxiwa volcanic rocks that belong to the same volcanic belt in the Pulu volcanic region, suggesting their origin from the same source region.However, the temperatures and oxygen fugacity of magmas at high-level magma chamber decreased along with fractional crystallization.
