The ore bodies show multi-layer mineralization characteristics, and are thick and rich in lower layers, and thin and weak in upper layers (Zhang et al., 2005; Cai, 2014). The shapes of whole ore bodies are tabular, stratoid, and/or lenticular . The dip angle is gentle, which is consistent with that of the ore-bearing formation (Rong et al., 2019).
