South African Journal of Geology (2021) 124 (3): 611–626.
...N.J. Wagner; M.L. Mokwena; A. Kolker Abstract The trace element data pool for South African coals is limited. However, certain elements are reported as occurring in considerably higher concentrations than global average values. These elements include chromium (Cr), as well as manganese (Mn), cobalt...

... in a limited way, with zones affected by in situ ferrugination. Cobalt has an atypical statistical distribution at Santa Fé if compared with other laterites, correlated not only with Mn but also with Cr in the majority of the laterite facies. From microchemical analyses on several potential Co-bearing minerals...

... were standardized using S and Fe on marcasite, Sb on antimony, Co on cobalt, Ni on nickel silicide, Cu on copper, Zn on sphalerite, As on gallium arsenide, Se on selenium, V on vanadium, and Ag on silver. The beam current was adjusted to ~12,000 counts per second for analyte and X-rays on gas-flow...

... phases, such as pyrite (FeS 2 ). Furthermore, the trace metal content of pyrite has been proposed as a marine paleoredox proxy. Given the diverse low-temperature diagenetic formation pathways for pyrite, this use of pyrite requires validation. We, therefore, studied nickel (Ni) and cobalt (Co...
