Abstract：Late Carboniferous-Early Permian post-collision plutons are extensively distributed throughout the West Junggar, Xinjiang,China,of which the Akebasitao pluton is the most distinguished one.However,investigations on the three-dimensional configuration and emplacement mechanism of the pluton remain relatively insufficient.A multidisciplinary approach,including field structure and audio magnetotelluric sounding,has been adopted for study on the Akebasitao pluton. The geological features and the audio magnetotelluric sounding exploration suggest that the pluton,with an asymmetrical mushroom-shape and slightly oblique movement of magma from NW to SE,formed in the post-orogenic extensional environ-ment.What is more,the three-dimensional configuartion of the pluton reveals that the West Junggar was of post-orogenic ex-tensional environment in the Late Carboniferous to Early Permian.This study has important implication for three-dimensional shape of those post-collision plutons that are widely developped in West Junggar.
