The metamorphic evolution of an ancient accretionary prism in the southern zone of the Damara Belt in Namibia
… strained, metamorphosed clastic sedimentary rocks that are intercalated with slices of metamorphosed basalt and gabbro. One of the only modern geological environments in which such vast amounts of sediments can be accumulated, with intercalated mafic rocks, is in an accretionary prism above a …

Investigating the metamorphic evolution of reworked terrains.
… first region is the Palaeo- to Mesoproterozoic rocks of the Gawler Craton. These rocks have experienced extensive granulite facies metamorphism at c. 1690 - 1665 and 1590 Ma and are poorly exposed. An understanding of the tectonothermal history of this region is important for resolving the …

Tectono-metamorphic history of the re-worked, high-grade Maud Belt at central-Eastern H.U. Sverdrupfjella, Antarctica
… Mineral assemblages and textures preserved in metapelitic and metamafic rocks preserve evidence of only one prograde to retrograde metamorphic cycle with peak mineral assemblages that are characteristic of granulites. Sillimanite in metapelitic rocks forms pseudomorphs after kyanite whereas …

Metamorphoseentwicklung im Kaokogürtel, NW-Namibia
Der Kaokogürtel in NW-Namibia gehört zu den panafrikanischen Orogensystemen Westgondwanas. Er besteht aus präpanafrikanischen Grundgebirgseinheiten und panafrikanischen vulkano-sedimentären Deckgebirgseinheiten, die einer grünschiefer- bis granulitfaziellen Metamorphose unterlagen. Für Metapelite …
