Abstract

The Cuyuna North Range was chosen as a study area because it has produced both iron ore and manganiferous iron ore from the Trommald Formation. Standard petrographic thin sections of this formation were studied for evidence of mechanisms involved in the precipitation of manganese. The microstructures suggest that microbial precipitation may have been a dominant factor in the precipitation of both iron and manganese in the Trommald Formation
