DOI: 10.1080/00206814.2017.1423521
Abstract: ABSTRACT Due to sparse data for deciphering the late Neoproterozoic tectonic history, there is still considerable debate on whether long-lasting superplume-related or long-duration subduction-related dynamics dominated the Tarim Craton. In this contribution, our field investigations… read more here.
