摘　　要：根据详细填图和研究资料，对区内中生代花岗岩类侵入体的分布特点、岩石学、地球化学、同位素年代学等进行了较系统总结，并对花岗岩类的起源及形成演化、顶蚀一塌陷侵位机制，及其与火山活动关系等作了较深入分析，为探讨大别山热隆史提供了较充分的地质依据。A systematic summary is made on the distribution,petrology,geochemistry and isotope chronologyof the Mesozoic granitoid intrusions in the area studied according to detailed mapping and research data. Theorigin of the granitoid is aiso described along with its formation,evolution,stoping-collapse emplacementmechanism and its relationship to volcanic activity.These provide a basis for discussing the ther1nal rise(ex-pansion )history of the Dabie Mt.
