Short summary
The Tethyan orogenic belt records an extensive history of subduction along the southern margin of Eurasia. We examine the magmatism, stratigraphy, and sedimentary provenance of the Jurassic basin in the West Kunlun Mountains, highlighting the switching extensional and contractional tectonic episodes in central Asia. The complex evolution was related to the subduction of the Neo-Tethys Ocean, transitioning from southward retreat to northward flat-slab advancement.
