BEIJING – Geologists from China and Myanmar have discovered new seismic proof to assist a mannequin that explains how the Indian subcontinent drifted northward anomalously quick and collided with Asia in historical instances.
The examine, printed on Saturday within the journal Science Advances, reveals that closure of the Neo-Tethys Ocean within the Mesozoic Period and the following formation of the Qinghai-Tibet Plateau had been possible brought on by double subduction, a geodynamic course of by which two plates following one another are synchronously subducted.
The researchers from the Chinese language Academy of Sciences, the Myanmar Geoscience Society, Yangon College and Dagon College carried out high-resolution investigation of higher mantle constructions beneath Myanmar.
The Myanmar area occupies the jap finish of the Indian-Asian collisional system. Resulting from much less remodeling from continental collision, it is a perfect place to probe potential slab remnants of double subduction, in accordance with the examine.
The analysis reveals, for the primary time, two subparallel subducted slabs preserved intact within the current higher mantle beneath the Neo-Tethyan tectonic regime, supporting the double subduction mannequin of the Neo-Tethys Ocean.
