Structural Environment and Age Discrimination of Volcanic Rocks in the Lower Permian Wulang Formation of the Dabate Area of Northern Sailimu Lake in the Western Tianshan Mountains
Through the study of the rock type,genetic characteristics and regional structural background of the Lower Permian Wulang Formation in the north Damat region of Saiimu Lake,the petrographic and geochemical characteristics are analyzed,and the results show that continental volcanic deposition has continental rift volcanic characteristics.Volca-nic rocks are mainly basalt rock,andesite rock,England rock and pyroclastic rocks,which are continental tectonic envi-ronments with non-orogenic environment.The Lower Permian Wulang Formation is the product of the early Permian vol-canic activity,as determined by biological fossils,lithological characteristics and isotopic data results.
