| Abstract: | The NNE-striking Haihui-Shibeishan tectonomagmatic belt in Lushan area is obviouslycontrolled jointly by extensional-segregational structure and left-lateral strike-slip shear structure since the Mesozoic-Cenozoic era. Regular variation trends are noted in granitoid of the various units whether in spatial distribution , in petrology, in petrochemistry or in trace elements and rare earth elements Genetical ly , the magmatic rock evolves from "S-type" towards "I-type" within the belt |
