The transition from oceanic to continental subduction and collision: A case study of the North Qaidam ultrahigh-pressure metamorphic belt, northern Tibetan Plateau
Anne Cadoret,Enrique Delamónica +1 more
TL;DR: In this paper , UHP eclogites with occurrence of coesite inclusions were collected from the northern Dulan terrane in the North Qaidam orogen, and they can be divided into three types according to their protolith features: (1) cumulate gabbro protoliths; (2) normal-to enriched-type mid-ocean ridge basalt; and (3) back-arc basalt contaminated by continental materials.
