The Norwich vein is thought to belong to the Anaconda vein system. It contains fairly large deposits of manganese. The study of 19 thin sections and 15 polished sections was made to determine the paragenesis of the vein minerals, which is: quartz-pyrite, rhodochrosite, quartz, minor rhodochrosite, quartz-pyrite-sphalerite, galena, freibergite and later quartz. Some supergene rhodochrosite was found and most of the silver minerals were found to be supergene origin.
