摘要
The constraints on the closure of the Tianshan ancient oceanic basin catches geology field attention, there has been 3 kinds of divarication for a long time, such as the Late Devonian or the initial Carboniferous, the Late Carboniferous, and during the Permian. Resuming prototype basin by, is the foundation for instauration of the orogenic belt ancient oceanic basin, and the calcalkaline volcanic rocks can also be the important evidence. According to these new data and analyses, the authors inferences the constraints on the closure of the Tianshan ancient oceanic basin can be only late stage of the Early Carboniferous.
