| Nanwutai Scenic Area of Buddhist Culture |
Nanwutai scenic area of Buddhist culture is a part of the Cuihuashan Mountain collapse-slide sub-geopark. It covers an area of 26.57 km2, in which the Wutai granite scenic spots and the Shengshou temple scenic spots are included.
The scenic area is featured in grey medium- to fine-grained granites and gneissic granite, well-developed faults and joints, clear outcrops of ductile-shear zone and many granitic pegmatite veins. Tectonic movement and mountain collapse-slide created a “museum of tectonics and geomorphology” in the area, forming isolated peaks, high platform, rhinoceros-like stone and tiger-like stone.
The Nanwutai scenic area is involved in the Cuihuashan sub-geopark and is one of the Buddhist Holy Lands in China. It was known as Nanwutai (South Five Terraces) for the existence of the five terraces of Datai, Wenshu, Qingliang, Lingying and Sheshen and the location in the south of Mt. Wutaishan.
Lithology in the Nanwutai scenic area is composed of grey-white moderate-sized granite and gneissic granite, in which faults and joints are well developed with features of ductile-shear zones. Veins of pegmatite are common in this area. Miraculous landscapes decorated by individual peaks, picturesque stones, lofty stone pillars might be called a museum of tectonic landscapes.
Plants in the Nanwutai area are abundant in spermatophytes, including the living fossils of plants, Spinulosa seconds tree of the Triassic period about 200 million years and the Seoul bottle grass of the Carboniferous period and Aesculus chinensis Bunge. In this area, we can see some residual virgin forest, big pine trees, cypress, Magnolia and sawtooth oak.
The Shengshou Temple was a holy place where the Emperors of ancient China worshiped, monks and taoists cultivated themselves according to a religious doctrine, and folks made pilgrimage and burnt incense here from Qin and Han Dynasties.
A normal fault appears in between pink medium-coarse granite and light-grey migmatitic granite. It strikes to northwest—southeast and dip to northeast with fractured zones, cataclastic rocks and associated joints developed well. The joint indicated the movement direction of the fault.
The fault is a major one in this area, which was formed in the Cenozoic era and impacted to the arrangement of the five terraces.
Long-term water erosion, freezing-and-thawing and spheroidal weathering shaped large grey-white migmatitic granite into appearance like a head of rhinoceros, in which some residual biotite, cross-cutting pegmatite veins and regularly broken quartz veins are visible. Otherwise, we can see several cypress trees and pine trees growing up from some fissures and joints of the rock.
The grey-white migmatitic granite collapsed and broken along joints in both the sides of the rock and formed a natural stone wall. It has a height of 5m and a width 1.2-1.5m, on the left side of which a group of rhombic joints is developed and partly filled with pegmatite and quartz veins.
Two gullies almost join together. It is the result of strong erosion toward dividing crest.
