This article discusses the region, east of Lilongan County, east of Anshan, west of Tangshan Tangjiazhuang, Luannan County from the south, north to Lulong County, an area of nearly 1400 square kilometers, the Jingshan railway runs east-west. Precambrian sedimentary metamorphic iron deposits are widespread in the area, which is an important iron ore resource base in China. For a long time, many units conducted a lot of production and scientific research in this area and accumulated rich geological data, which provided a good foundation for the study of metallogenic regularity and metallogenic prediction.
