Mount Tai runs through the central part of Shandong and is in Tai 'an City. Mount Tai, stretching between Tai 'an, Jinan and Zibo, was called "Daishan" and "Daizong" in ancient times, but it was renamed "Mount Tai" in the Spring and Autumn Period. Mount Tai is adjacent to Qufu, Confucius' hometown, and backed by Jinan, the spring city.
Mount Tai rises in the eastern part of North China Plain, above Qilu Plain, with the sea in the east, the Yellow River in the west and the water of Wenzhou, Suzhou and Huaihe River in the south. It is about 200 kilometers long from east to west and 50 kilometers wide from north to south. The main vein and branch vein involve more than ten surrounding counties, with a lying area of 426 square kilometers, and the elevation of the main peak Yuhuang Peak is 1532.7 meters.
Mount Tai is the highest mountain range in the hills of Shandong. This stratum is a typical basement and caprock structural area of North China Platform. The uplift in the south is large, and the cover is weathered off, exposing a large basement-Taishan complex, that is, the Archaean Taishan Group stratum. Its absolute age is about 2.5 billion years, and it is one of the oldest strata in China.
