摘要：
The volcanic rocks in western part of Jinshajiang structural belt are zonally distributed between Qiangtang and Kunlun landmasses. It is bounded on the north by Yanghu\|Hoh Xil deep fault and on the south by Bairabu Co\|Ruolagangri deep fault. As component part of ophiolites in this belt, volcanic rocks consist of basalts, dorgalites, picrites, basaltic\|andesites, andesites and a few pyroclastic rocks. They mainly occur within low\|grade metamorphic and thick flysch deposits of Lower Permian and Late Triassic and are associated with gabbro, diabase, ultramafites, radiolarian silicalites and limestones. This suit of volcanics\|bearing flysch deposits had been considered as Triassic or Late Triassic stratum and also called as “Ruolagangri Group”.
