文摘

The Dashitou bimodal volcanic rocks in the Eastern Tianshan erupted at 330 ± 3 Ma. The basalts were originated from a depleted mantle source fluxed by slab-derived fluids. The rhyolites were generated by partial melting of a juvenile basaltic crust. Tectonic response to the rifting of the Dananhu–Harlik arc.
