| 摘 要： | 首次在内蒙克什克腾旗增内的大兴安岭山脉的北大山上，发现世界罕见的花岗岩石林地貌景观。花岗岩石林是在特殊的内、外动力作用下形成的。花岗岩中的节理和裂隙是形成石林的构造基础；在古冰川、寒冻风化、风和水等外力作用下形成了石林。其形成和发育过程主要分为：冰川作用；寒冻风化、风和水等外力作用下形成了石林。其形成和发育过程主要分为：冰川作用；寒冻风化作用；风蚀作用和夷平作用４个阶段。花岗岩石林地貌是花岗岩地貌

| Abstract: | A landscape of granite hoodoos can be seen well developed in Beidashan of the Daixingainling mountain range in Keshiketeng county,Inner Mongol Autonomous Region.Granite hoodoos are formed by freezing,weathering,aeolation of the jointss and crackes developed in the granite.There can be distinguished four stages in their formation:glaciation,freezing weathering,aeolation and planation.It is a new type of the granite landforms,often occurring in an expense of land several hundred metres long,decades of metres wide 5~20 m high,with some individual pillars standing as high as over 20 m.They are very specular,grotesque,sometimes one linked with another to form a fantastic screen.It is forming an attractive item of tourism geology. |
