Mössbauer effect characterization of Brazilian iron ores for mining industrial purposes
(Elsevier, 1993-04-04) Araujo, Jose Humberto; Costa Jr., M. I. da; Kunrath, J. I.; Cunha, J. B. M. da; Moro, J. T.
Iron ore is one of the important export products of Brazil. As only ore bodies with over 50% iron contents are mined, continuous efforts in prospecting are made. The use of Mössbauer spectroscopy as an aid to these efforts is illustrated by an example given in this report.
Mössbauer effect study of a pleistocenic Brazilian fossil
(Springer, 1991-11) Araújo, José Humberto de; Kunrath, J. I.; Costa Jr, M. I. da; Vasquez, A.; Alves Jr, C.; Oliveira, L. D. Dantas de
Some preliminary Mössbauer effect results for a pleistocenic bone fossilized by mineralization process are presented. The presence of some iron-sulphur compounds permits to infer a correlation between the oxidation state of iron and the environmental conditions of fossilization
