Discovery and Origin of Mafic Microgranular Enclaves of the Dulunhe Magma Mixing Granite in West Junggar
摘要
Abstract
As a result of intensive magmatic activity in Neopaleozoic,large amount of intrusive granites exposed along the Daerbute fault in the center of western Junggar.Many researches have been conducted with the batholites,few focused on the small granite intrusions which mainly dis-tributed in porphyry mineralization belt of the Baogutu region.Dulunhe granite is located in Kuoyitasi area of Zhayi’er Mountain,and its host rock mainly consists of medium-grain quartz di-orite,medium-coarse granodiorite and medium-coarse biotite granodiorite.Abundant mafic mi-crogranular enclaves can be found in the host rocks.Field distribution and petrology features of mafic enclave suggest that the Dulunhe granite is resulted from mixing of hyperthermal mantle-derived basic magma and crustal acid magma of relatively lower temperature,which provides im-portant evidence for the origin of Dulunhe granite and crust-mantle magma migmatization in the study area,and also has great regional significance for the studies of the genetic type and diversity of the granite in west Junggar.关键词
