Yanshanian is the most important and intense magmatic activities in China. In this paper

through summarizing predecessors’ research on southern China in the late yanshan

found that the magmatic activity can be divided into two periods

the early late yanshan magma activity mainly distributed in the middle and lower reaches of the Yangtze river region and the southeast coastal area

late late yanshanian magmatic activity mainly concentrated in the west of wuyi mountain area.Through the SiO 2-Alk graphic and AFM diagrams and Sr

Nd

Pb isotopes of source rock type and classification

and according to the law of the late yanshanian magmatic activity and the late yanshan metallogenic relationship building.
