Abstract

A Ni-Co-As ore sample from Cobalt City, Ontario, Canada was examined with Scanning electron microscopy and Energy Dispersive X-ray analysis. In addition to cobaltian (para)rammelsbergite with variable cobalt content, for which Cobalt City is the type locality, and erythrite one new minerals was observed for this locality. Well formed crystals of arsenolite, As2O3, were found embedded in what appears to be fibrous spherocobaltite, CoCO3. Additional information was obtained by Raman microscopy confirming the identification of the arsenolite. Both are considered to be secondary minerals formed by exposure to air resulting in oxidation and the formation of secondary carbonates.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
