摘　　要：Objective The Chinese Altai as a key part of the Central Asian Orogenic Belt is characterized by numerous outcrops of Paleozoic granitoids and minor mafic plutons (Fig. 1a). It is widely accepted that Devonian ridge subduction played an important role in the tectonic evolution of the Chinese Altai. However, Carboniferous magmatism related to ridge subduction has received little attention. Moreover。
