Microfossils or pseudofossils? Cu-Co sulphide microfeatures in the Neoproterozoic Katangan Supergroup, Democratic Republic of Congo

In this paper we investigate a group of microfeatures discovered in the mineralised, Neoproterozoic Mines Subgroup of the Katangan Copperbelt, Democratic Republic of Congo (DRC), at the Mashitu South Cu-Co deposit. The features are bacillus-shaped, composed of Cu-Co sulphides and occur within syn-diagenetic apatite veins in a low-grade metasedimentary shale. They exhibit a range of evidence for biogenicity, including indicators of cellular...
