九华山大断裂是南北向长33千米，东西向宽10-100米的破碎带。断裂带两侧岩块的错位运动产生次生构造应力场，使断裂带两盘岩石出现节理网络，称为伴生节理，分别是东西向和南北向的两组剪压性节理。九华山大断裂带和两组节理就是九华山花岗岩地形发育的断控节理构造，流水、冰雪、风、重力沿断控节理构造，差异性剥蚀风化剥离九华山花岗岩，塑造出多尺度、多类型的山丘盆地形与花岗岩奇峰异石。

Jiuhuashan Great Fracture is a shuttered zone, 33km long from south to north ,10-100m wide from east to west.  The displacement movement of rocks on both sides of the fault zone generates secondary tectonic stress field , causing two sets of rocks of the fault zone to have joints network, called accompanying joints： two groups of shearing compressional joints respectively in east-west direction and in south-north direction. Jiuhuashan Great Fault Zone and two groups of joints are resulted from Jiuhuashan granite landform. Jiuhuashan granite is peeled off through differential erosion and weathering of running water, ice snow, wind and gravity along joint structure, creating diverse mountain-hill-basin terrain and bizarre granite peaks and rocks.
