文摘

The studied volcanic rocks in the Raohe accretionary complex were formed in the Early Jurassic (187–174 Ma). The calc-alkaline volcanic rocks are the products of crustal contributions. The Nb-enriched and high-Mg volcanic rocks were derived from mantle wedge. The Paleo-Pacific Oceanic Plate westward subduction beneath Northeast China probably existed during the Early Jurassic.
