Cuihuashan is a part of the Qinling Mountains that is composed of the Middle Proterozoic (1,000 million years ago) metamorphic rocks. A large active fault is located along the northern foothills of the Qinling Mountains. The northern side of this fault has subsided to form the Guangzhong Plain. Its southern side has been uplifted, causing the formation of the towering Qinling Mountains. Over the past 10,000 years, the uplift rate was 34–173 mm/year. Due to the severe fracturing, the brittle and hard nature of the rock of Mount Cuihua and the occurrence of torrential rain, landslides are common and have resulted in the accumulation of a collapsed mass with a volume of 300 million cubic metres at Cuihuashan and the formation of features such as rugged peaks, broken cliffs, collapse block fields and landslide dams (Tianchi) (Fig. 61).
