浙江花岗岩地貌特征与形成过程

Characteristics and Forming Processes of Granite Landforms in Zhejiang Province

浙江地处东亚大陆边缘,江南陆块与华夏陆块的交接部位,构造作用和岩浆作用,特别是中生代的花岗质岩浆作用十分强烈,形成大量的花岗岩类,它们是构成浙江花岗岩地貌的物质基础。浙江花岗岩地貌可分为花岗岩峰丛、花岗岩山丘、花岗岩石蛋和花岗岩崩塌堆积地貌等。作者以大明山、天台山、普陀山及浮盖山等为例,论述了以上各种花岗岩地貌的特征,并对其形成过程进行探讨,同时也讨论了岩石性质、地质构造和气候条件等对花岗岩地貌发育与演变的影响。

Zhejiang is located at the East Asiatic continental margin, ano is situated in the contact belt between the Jiangnan block and the Cathaysian block. Structural and magmatic activities, especially the Mesozoic magmatic ones, are extremely intensive, which form massive granitoids. The granitoids constitute materials of granite landform in Zhejiang Province. The Zhejiang granite landforms may be classified into the granitic peak cluster, granitic hill, granite nubbin and collapse pile landforms and so on. Taking the granite landform are discussed as well.
