Hubei, Middle-Lower Yangtze metallogenic belt, China

SkarnsFe (Cu)

Type: Iron (magnetite) skarns related to Jurassic-Cretaceous intrusions

Set of high-grade iron skarns related to Jurassic-Cretaceous intermediate to acid intrusions (Xie et al., 2006). Dong et al. (2022) give neither the mine names nor their position (samples 160u, RJW, LJS and FJS). Coordinates not published.
