Abstract: Mesozoic intrusive rocks in Shanxi Province were divided into three magma series according to the regional geological survey, which were alkaline- subalkaline series, subalkaline (base-)—medium acid series, type A-granite (acid) series. Alkaline-subalkaline series were formed in the post-collision tectonic environment. Subalkaline (base-)—medium acid series were formed in continental island arc, continental edge arc and post-mountain tectonic environment. Type A-granite (acid) series were formed in the construction environment of in rift valley in the plate subduction or the mantle hotspots (mantle plume), and the heat and aqueous solution was provided by the plate subduction. The geotectonic division belongs to the tectonic magma provinces in North China Craton, including three magma belts (Grade II), which are southern Xingmeng magma belt, northern Qinling Mountains magma belt and eastern North China magma belt. Each magma belt can be divided into two subzones ( Stage 2 Magma Action) (Grade Ⅲ), and each subzone has the characters of igneous rocks in the plate subduction zone and the evolution polarity. This achievement can provide some reference for landing problems of the plate structure.
