The surface of Siguniang Mountain is mainly composed of sandstone, slate, marble, limestone and crystalline limestone in Mesozoic and Paleozoic. Siguniang Mountain is located in the transition zone from the western Sichuan Plateau to the Chengdu Plain.
Since Mesozoic, mining and Triassic Indosinian movement have dominated, and they have experienced many tectonic changes. There are strong folds, mountain uplift, stratigraphic metamorphism, revival of old faults and river undercutting in this area. All these internal and external forces have caused the complex topographic features of the height difference between Siguniang Mountain and the valley.
To the east of Siguniang Mountain, there is the rushing Minjiang River, and to the west, there is the Dadu River, which is known as the "natural barrier". The valley has a mild climate, abundant rainfall, mountain flowers everywhere, clear streams, surrounded by glaciers on the mountainside, and steep and snowy peaks.
