The origin of place names

Mianyang, located in the south of Mianshan, was named Mianyang in 1913 according to the ancient meaning of "Yang" in the south of the mountains and the north of the rivers.

History of construction

Mianyang City is one of the early human activity areas in China. There are 4500 years old Neolithic stone tools and pottery unearthed from the bianduishan site.

In the second year of Gaozu in the Western Han Dynasty (201 BC), Fu County was established. Guanghan county was established in the sixth year of emperor Gaozu (201 BC). In 106 BC, Guanghan County moved from Chengxiang (now Guanghan City) to Zitong county.

In the first year of ruziying (8 years), Wang Mang usurped the Han Dynasty to establish a new dynasty, and changed Fu County into Tongmu County, which implied the meaning of unity and harmony, so it got its name and belonged to Jiudu county.

In the 37th year of Emperor Guangwu's reign in the Eastern Han Dynasty, his family was destroyed and Fu County was restored, belonging to Guanghan county.

In the second year of emperor an's reign in the Eastern Han Dynasty (115), both the governor's Department of Yizhou and Guanghan County moved to Fu County. Three years later, both the prefecture and the county moved out of the city.

At the end of the Eastern Han Dynasty, Liu Bei ruled Shu. In the 22nd year of Jian'an (217), Zitong county was set up in the northern part of Guanghan county (governing Zitong county), and in the third year of Jianxing (225), dongguanghan county was set up in the eastern part of Guanghan County (governing Santai County). Since then, the city has been built in all generations, including prefectures, counties and prefectures.

geological structure

In Mianyang City, the strata are well developed, the rock formations are complex, and the lithology and lithofacies change greatly; the structural morphology is extremely complex due to multiple structural inheritance, interference and superposition; the late magmatic activity and regional metamorphism are weak; the sedimentary mineralization is strong, and the endogenetic mineralization is weak. Taking Jiangyou fault as the boundary, it is divided into two first-order structural units. According to the plate theory, it is located in the meridional chimeric zone of the East and West plates in China, and according to the theory of trough platform, it straddles the Ganzi Songpan geosyncline and the Yangtze platform obliquely. This regional geological pattern controls the spatial distribution and combination characteristics of natural conditions and resources, such as lithofacies, strata, minerals, topography, geomorphology, soil, climate, water system and biology, and has a profound impact on human social and economic activities.

stratum

The strata of Mianyang city span two first-class areas: Yangtze area and Bayan Har Qinling area. It includes four divisions, namely Sichuan Basin division, Longmenshan division, markang division and West Qinling division; six stratigraphic districts, namely Nanchong District, Guangyuan District, north section of Longmenshan District, middle section of Longmenshan District, Jinchuan district and Motianling district.
