摘要: 根据1:25万马鬃山幅区调填图资料,从造山带不同构造单元的火山-沉积建造、岩浆岩序列演化、变质变形特征及时空配位关系研究入手,应用大地构造相划分理论,根据北山多旋回复合造山带的特点,识别出15种大地构造相,并探讨了北山古生代构造格局与构造演化模式.Abstract: On the basis of 1:250 000 scale regional geological survey of the Mazongshan map,through studied the volcanic-sedimentary formation,the evolution of magmatic rocks squence,the characteristics of metamorphism and space of every tectonic units of Beishan orogenic belt,and applied tectonic facies division theories,according to the characteristic of belt,Beishan polycycle multiple orogenic belt is respectively divided 15 sorts tectonic facies,and discussed its tectonic framework and tectonic evolution model in the Paleo soic.
