Abstract

Abstract

In this paper, we report the occurrence and mineral components of the enclaves, firstly discovered in the Cenozoic Pulu volcanic rocks in West Kunlun Mountains, and propose that the enclaves are accumulated by fractional crystallization within high level magma chamber. In addition, we have calculated the compositions of its primary magma. The calculated compositions are similar to those of the Kangxiwa volcanic rocks that belong to a same volcanic belt with the Pulu volcanic region, suggesting that they could have originated from the same source region. However, the temperatures and oxygen fugacity of magmas at high level magma chamber decreased along with fractional crystallization.
