Yangtze inland areas of Mesozoic magmatism is an area of intense late Yanshan tectonic Asia early stages of its formation of large volcanic region by a series of mafic to acid rock mix. Magma source region of the Yangtze inland areas mainly depleted mantle end-member mixing DMM and enriched mantle end-member EM Ⅱ

the source should have the properties of enriched lithospheric mantle

Yangtze inland areas of the Mesozoic volcanic igneous province in eastern China an important part of which is formed by the Chinese Mesozoic Yanshan period of geodynamic constraints. The area has experienced in the Mesozoic tectonic transition region and major adjustment process

the region in the late Mesozoic crustal thickening may be experienced

tension

lower crustal delamination

lithospheric thinning

upwelling asthenosphere and crust-mantle interaction dynamics of evolution.
