Stratigraphic units exposed in the mining district include the Lower Triassic Helongshan (T1h) and Nanlinghu Formation (T1n), the Middle Triassic Huangmaqing Formation (T2h), the Jurassic-Cretaceous volcanic-sedimentary strata (J-K), and the Wanghudun Formation of the Eocene (E1w), and Quaternary (Q). The Dayaocun deposit is located to the east of the Laojiacui intrusion, which extends in a NE-SW direction across the Xihu-Laojiacui area and occurs in a stock-like form. Magmatic rocks in the mining area are primarily represented by the Laojiacui granodiorite and Liqiao quartz diorite. Geological observations indicate that the ore-related rock is granodiorite which is close to skarn and magnetite ore body, while quartz diorite may be a later-stage dike. The Dayaocun high-grade Fe skarn deposit (6.03 million tonnes at 51.41 % TFe), recently discovered in the northern section of the Tongling ore-cluster area within the Middle-Lower Yangtze River Metallogenic Belt.
