On the basis of the studying of intrusive rocks of Taihang Mountains in Yanshanian, we compare the petrochemical and geochemical characteristics and their generation information from intrusives of different periods and regions in details. We suggest the idea of “Taihangshan style orogen” and its generation model. It is suggested that Taihangshan orogen is a new orogenic type, which is controlled by the long distance effect of the subduction between the plate boundaries of Europe Asian and Pacific Ocean, marked by extensive magmatic activity, and characterized by the two way thickening of the crust along the depth dimension.展开更多
