Bauxite deposit, hosted in the lower part of the middle Carboniferous Benxi formation occurring on an erosion surface of limestones of the middle Ordovician Fengfeng formation. The orebodies have a clear cut boundary with their hanging wall and footwall. The footwall rock is mostly ferrous and aluminous rock whereas the hanging wall rock is mostly composed of hard refractory clay, clay rock and clay shale. The bodies are bedded and the thickness and shape are controlled by the paleo-erosion surface on the limestone. The main deposit mineral textures are rough, oolitic and fragmental and minor pisolitic. Their structures are mainly massive, locally laminated and hollow.
