Geological conditions of Jiangsu Province

jiangsu Province is located in the North China plate, the eastern section of the Qinling Dabie orogenic belt, and the Yangtze plate, which cross the Chinese Mainland. The regional geological background and tectono magmatic activity are obviously different. The development process and evolution history of the geological structure of each tectonic unit are extremely complex. In general, it can be divided into three tectonic stages: micro landmass convergence and crystalline basement formation, plate convergence and reorganization, and the evolution of the Mesozoic Cenozoic continental margin active zone. The development process of the three units has undergone relatively independent development → multiple tectonic integration → co evolution. Sedimentary rocks, metamorphic rocks, and igneous rocks are widely developed, with different characteristics in different units, and have good geological conditions for mineralization

From a tectonic perspective, jiangsu is divided into two zones: the southern and northern zones, with the Xuyi Xiangshui Fault Zone as the boundary. The northern region was formed in the Archean period and has a relatively stable structure. It is the southeastern edge of the North China ancient land (also known as the North China Platform or the Sino Korean Platform). The southern region was formed in the Upper Proterozoic and is the easternmost end of the Yangtze ancient land (also known as the Yangtze Qiantang quasi geosyncline or Yangtze quasi platform). The northern region is mainly characterized by uplift, while the southern region is mainly characterized by subsidence. The lithology and geological structure constrain the development of jiangsu's landform, especially the new tectonic movements since the Quaternary period, which ultimately established the pattern of jiangsu's landform dominated by plains

jiangsu Province is located in eastern China, with geological structures bounded by the three major regions of North China, Sulu, and South China. The geological development is relatively complete, and it is one of the important areas for early geological research in China. Based on previous research data, the stratigraphic division of jiangsu is as follows: North China stratigraphic region (referred to as North China region); Lianyungang stratigraphic area of the Sulu orogenic belt (referred to as Lianyungang area); The Yangtze Stratigraphic Region of the South China Stratigraphic Region (referred to as the Yangtze Region)
