Granite Canyon

Reference work entry

This is a valley in a granite area with steep slopes, where the depth of the valley is greater than the width. They generally develop along tectonic faults in locations of intense uplift. Granite canyons form easily when the rate of uplift is similar to the rate of water erosion. For example, due to uplift associated with neotectonic movements, the Huangshan granite body has reached an elevation of more than 1,800 m. Coupled with the development of faults and strong erosion from abundant rainfall, a group of deep canyons that radiate from the centre of the rock body into the surrounding areas has formed. The Xihai Grand Canyon formed as a result of erosion by water along a NE-SW-trending fault line (Fig. 24).
