Volcanic-sedimentary Fe-Cu deposit, hosted in sedimentary rocks (amphibole biotite schist, albite leptite, silicious rocks, chelmsfordite marble, etc.), and related to basic volcanic rocks and marbles of the upper Manganghe and lower Feiweihe formations of the Lower Proterozoic Dahonghsan Group. The ore bodies are bedded, bedded-like and lenticular, conformable to the country rocks, and are folded together with the latter occasionally.
The deposit is composed of layered orebodies formed by volcanic exhalation sedimentation metamorphism and veined orebodies formed by hydrothermal superposition. The exposed strata of the deposit, from old to new, are the Archean Dibadu Formation (Ard) (strong metamorphic migmatite and schist), which is typically angular unconformity or pseudo-conformity connecting with the overlying strata. The Early Proterozoic Dahongshan Group, from old to new, includes the Laochanghe (Pt1dl), Manganghe (Pt1dm), Hongshan (Pt1dh), Feiweihe (Pt1df), and Potou (Pt1dp) formations. The Manganghe Formation is dominated by abyssal submarine volcanic eruption sedimentary formation [10], divided into four lithologic sections from the bottom to the top, which are primarily hornblende sodium-feldspar schist (Pt1dm1), garnet hornblende sodium-feldspar schist (Pt1dm2), garnet hornblende/biotite schist intercalated with sodium tuff (Pt1dm3), and pillared dolomite marble (Pt1dm4). Pt1dm3 is the primary occurrence horizon of layered Cu deposits. The sandstones of the Upper Triassic Ganhaizi (T3g) and Shezi (T3s) formations are in the Dahongshan Group and exhibit angular unconformity contact with the underlying strata. The quaternary residual slope layer (Q) is distributed in the valley and valley slope area within the mining area.
The deposit primarily develops I, II, III, and VI orebodies; the I orebody is the largest. The deposit contains 458 Mt, 41% Fe, and a large amount of Au (16 t), Ag (141 t), Co (1156 t), and Pd + Pt (2.1 t). The I3 orebody was selected for study, and it has an average Cu content of 0.76%. The average thickness of the orebody is 9.43 m. The orebody is hosted in metamorphic tuff. Bounded by the B128 line, the orebody in the west is NNW-trending and in the east NWW-trending, with an overall tendency of S.
