I. Location and background

Changsha is located in the northeast of Hunan Province, the lower reaches of Xiangjiang River and the western edge of Changsha Basin. Between east longitude11153 ′ ~1415 ′ and north latitude 27 51′. It is adjacent to Yichun and Pingxiang in Jiangxi in the east, Zhuzhou and Xiangtan in the south, Loudi and Yiyang in the west and Yueyang and Yiyang in the north. It is about 230 kilometers long from east to west and 88 kilometers wide from north to south. Area 1 18 19 km2. ?

Second, the geological characteristics

The geological characteristics of Changsha are: the strata are completely exposed, the granite bodies are widely distributed and the geological structure is complex. Various geological and historical strata are exposed in Changsha, and the oldest stratum was formed about 1 100 million years ago.

About 600 million years ago, Changsha was still a sea of Wang Yang, but the sea was not deep. After that, the sea gradually withdrew from east to west, and most areas of Liuyang, Changsha and Wangcheng surfaced, becoming the northwest edge of Jiangnan ancient land.

About/kloc-0.40 billion years ago, the seawater immersion in Changsha area ended and rose to land. Due to the influence of crustal movement and geological structure, a long-strip intermountain depression basin-Chang (Sha) Ping (Jiang) basin has been formed. Since Cenozoic, the whole Changping basin has risen to land. About 3.5 million years ago, the third ice age occurred on the earth, and Liuyang preserved the remains of glacial landforms.
