Metabasites from Namibe Province, SW-Angola: An Archean komatiitic magmatism?

1999
Metabasite 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 ...

Garnet-bearing metabasites from the blastomylonitic graben, western Galicia, Spain

1978
The present study deals with polyphase deformed and metamorphosed basic rocks from the Blastomylonitic Graben. The Blastomylonitic Graben is one of a number of meso- to catazonal complexes of probably Precambrian age in north-western Spain and northern Portugal.
