(The George Washington University. Department of Earth and Environmental Sciences)
Chromitites associated with strongly altered peridotite from six distinct localities in the Santa Elena ultramafic nappe (Costa Rica) have been investigated for the first time. Santa Elena chromitites commonly display a compositional variation from extremely chromiferous (Cr/(Cr+Al)=0. [...]

9 p, 287.1 KB Exotic accessory minerals in layered chromitites of the Campo Formoso complex (Brazil) / Zaccarini, F. (University of Leoben. Department of Applied Geological Sciences and Geophysics) ; Garuti, G. (University of Modena and Reggio Emilia. Dipartimento di Scienze della Terra) ; Martin, R. F. (McGill University. Department of Earth and Planetary Sciences) ; Instituto Andaluz de Ciencias de la Tierra
The Campo Formoso stratiform intrusive complex, in Bahia State, Brazil, considered to be of Paleoproterozoic age, consists of a tabular body of ultramafic rocks about 40 km long and 100-1100 m wide. Thick horizons of chromitite are exploited and the deposits are the richest in Brazil. [...]
