The Nanmushu zinc–lead deposit is hosted by the Dengying Formation (Z2dn) and lies on the northern margin of Sichuan Basin, China. The deposit is a Mississippi Valley-type (MVT) lead–zinc deposit associated with bitumen. The bitumen can be divided into early and late bitumen, although the abundant late bitumen is unrelated to the Zn–Pb orebodies. Mineral …

The lead-zinc ores occur in a shear zone in Precambrian metasediments. The shear zone is later than the two recognized generations of folds, and contemporaneous with wall-rock alteration and subsequent mineralization. Flow directions of mineralizing solutions are deduced from the mineral zoning pattern; galena follows sphalerite paragenetically ...

The role of hydrocarbon fluids in metal mineralization is a key topic in lead-zinc ore formation studies. Hydrocarbon fluids may contribute to the remobilization, enrichment, migration, and precipitation of metals (Anderson, 2008, 2015; Hurtig et al., 2018).Crude oil and its derivatives can directly provide reducing sulfur or agents for thermochemical sulfate reduction (TSR), …

The Benue Trough of Nigeria is a sedimentary basin that extends from the Gulf of Guinea in the southwest to the Chad Basin in the northwest for about 800 km in length and 150 km in width. Lead-zinc-barytes occurs in almost the entire length of the Benue Trough. Lead-zinc-barytes mineralization in the Trough is believed to be hydrothermal in origin and is associated with …
