Devonian to carboniferous tectonic evolution of the Kangguer Ocean in the Eastern Tianshan, NW China: Insights from three episodes of granitoids

Deciphering the tectonic evolution of the Kangguer Ocean is critical to understand the architecture of the Eastern Tianshan, NW China. Previous studies for the Kangguer Ocean mainly concentrated on final closure during the Latest Carboniferous to Permian. Three distinct episodes of granitoids have been recognized in the Kangguer belt: Late Devonian (ca. 360 Ma) normal I-type granites, Early Carboniferous (ca. 348 Ma) fractionated I-type...
