...Brendan M. Clarke Abstract This paper describes the field geology of the Natal Metamorphic Province (NMP) as exposed on the Durban 1:50 000 map sheet, and applies the established lithostratigraphic subdivision of the southern Mzumbe terrane to these rocks. Supracrustal gneisses of the Mapumulo...

...R. J. Thomas; D. H. Cornell; R. A. Armstrong Abstract Layered gneisses of the Quha Formation make up the oldest component of the Mzumbe terrane, Natal Metamorphic Province. They have been interpreted as predominantly metamorphosed andesitic volcanic rocks and their sedimentary derivatives, formed...

... Lesotho granulites occurred at ~1.10, ~1.04 and ~1.00 Ga, first in response to crustal thickening associated with thrust stacking of the Tugela terranes across the southern margin of the Kaapvaal craton and juxtaposition of the adjoined Mzumbe terrane at ~1.10 Ga, and then by subsequent crustal accretion...

... Ga arc- related intrusive and supracrustal rocks of the Mzumbe terrane to the north. The new date has rendered this interpretation untenable, as it shows that the gneiss is approximately coeval with granitoids and charnockites of the Oribi Gorge Suite, which have a within-plate signature.

... in the Margate Terrane. This is ~60 Ma later than the completion of the main tectonism (D 1–3 ) documented from the Tugela Terrane, suggesting diachronous arc accretion. Syntectonic granitoids with ages of ~1090 Ma have also been documented from the Mzumbe terrane, as well as from Western Dronning Maud Land...

... providing a reliable upper age of ~1.07 to 1.08 Ga for D 3 in the Margate Terrane. This upper age is ~20 to 47 Ma older than that determined for the D 3 event in the Mzumbe Terrane. Integration with newly constrained ages of the D 1 (~1.09 Ga) and D 2 (1.09 to 1.06 Ga) events illustrate their temporal...

Published: 01 December 2003
subduction is occurring, of the Mzumbe Terrane to the south. The Mfongosi Basin is essentially a kidney-shaped depression, deepening towards its eastern parts, which contain predominantly medium- and coarse-grained metasediments, grading into a N-MORB + metapelite-dominated terrane in its western parts.

... that the entire Tugela Terrane overlies Archaean crust. The Mzumbe Terrane covers a large area south of the Lilani-Matigulu shear zone. It consists of supracrustal gneisses that were intruded by a wide range of meta-igneous rocks including TTG orthogneisses and by later gabbros ( Thomas, 1989 ). The Mzumbe...
