Magmatic Chromian Spinel in Metabasite From the Latimojong Mountains, Sulawesi, Indonesia
2022In metavolcanic rocks of the Latimojong Mountains, central Sulawesi, Indonesia, chromian spinel spans a wide compositional range in Cr/(Cr+Al). Spinel occurs in the matrix of metamorphic silicates (Chl+Act+Pmp) and as inclusions in magmatic clinopyroxene phenocrysts (Fig. 1).

A Comparison of amphiboles from medium- and low-pressure metabasites
Contributions to Mineralogy and Petrology, 1982A comparison of published metabasite amphibole analyses from medium and low-pressure metamorphic terrains reveals that there is no systematic variation in Na, NaM4, Al or AlVI as a function of pressure. This may be due to blurring of the differences by variation in oxidation state, or by analytical differences between laboratories.

Metabasites from Namibe Province, SW-Angola: An Archean komatiitic magmatism?
1999Metabasite intercalations in Precambrian metasedimentary sequences from Namibe Province, southwestern Angola, show strong geochemical affinity with komatiites and komatiitic basalts. Rb-Sr systematics, probably "perturbed" by polymetamorphic processes, as well as by crustal contamination and alteration, seem to indicate two main thermal events, at 2.0 ...
