摘要
Through the detailed research on petrography, mineralogy, contact relation, wallrock structures and forming age, according to the classification principles of tectono-magmatic evolutionary times, the intrusive rocks on the west Alashankou in Xinjiang Region is disintegrated and regrouped as the Carboniferous crust-mantle mixed succession, including eight intrusive sequences, with pulsatile contact relation between each sequence. Considering the form, structure and the deformation and metamorphism of wallrocks, the Kezilezhayilao big batholith is passively emplaced with the balloon-like inflation in the pull-apart stress field that formed between the northwest-trending strike-slip faults.
