Sedimentary response to the Early-Mid Permian basaltic magmatism in the Tarim plate

Abstract：In the Tarim plate there is a great deal of basic igneous rocks including basalt, diabase and basaltic andesite formed by the Early to Middle Permian intraplate magmatism, and their residuals cover an area of about 200 000 km2. The Permian was a very important transition stage in the evolution of the Tarim plate. In the late Early Permian the Tarim basin ended marine sedimentation and entered the stage of continental sedimentation. On the basis of an analysis of the characteristic of the Early to Middle Permian basaltic magmatism and Carboniferous to Permian sedimentary facies in the Tarim basin, this paper discusses the controls of this large-scale magmatism on the Carboniferous to Permian sedimentation and puts forward a model of the sedimentary response to the Early to Middle Permian basaltic magmatism in the Tarim plate.
