Zircon U-Pb age and geochemistry of the Carboniferous porphyritic granite and granodiorite from the Akebasitao pluton in Eastern Junggar Basin:Constraint on tectonics
The genesis of the Akebasitao pluton in Junggar Basin is discussed,and its regional tectonic setting and the structural features are studied by means of geochemical methods.Field investigation and application of geochronology,petrography and geochemical features of the pluton showed that the pluton was formed in the late Carboniferous Moscovian.Akebasitao pluton is mainly composed of porphyritic granite and granodiorite.Geochemical study shows that the porphyritic granite is characterized by high silicon co...
