The emplaerment mechanisms and its derived structures of granitoids is the frontal thesis and grewing point of the contemporary granite geology, and is also the important part of structural gelolgy. Based on the discription of the study significance of the emplacement mechanisms of granitoids, this paper reviews the research advances of some main emplacement mechanisms of granite plutons,the control factors of the emplacement mechanisms and the study methods of the emplacement mechanisms. Finally, the author put forward same proposals for strengthening the study on the emplacement mechanisms and strctures of granitoids in our country.
