GEOMORPHOLOGY OF MIAROLITIC SYENGRANITE IN SHIRENGOU, INNER MONGOLIA

With study on the geomorphic forms and genesis of miarolitic syengranite in Shirengounanshan, Inner Mongolia, it is revealed that the unique geomorphic types include pebbly landform, drasy cavity, etc., with the Early Cretaceous A-type miarolitic syengranite as the landscaped rock. The NNE-NE and NW-trending faults, fissures and joints basically control the shape and size of mountains. Weathering denudation, water erosion and gravitational collapse are the major external power that forms the miarolitic syengranite landforms. The unique landscaped rock and various geomorphic types make it the rare geological heritage and tourism resources.
