Can mineral equilibrium modelling provide additional details on metamorphism of the Barberton garnet amphibolites?

Publikováno v: South African Journal of Geology. 124:211-224

The Stolzburg domain to the south of the Barberton Greenstone Belt preserves evidence for a 3.23 Ga subduction–collision tectonic event. Garnet amphibolite greenstone remnants have previously yielded conventional thermobarometric P-T estimates of 1

Processes, properties, and microstructures in faults active at retrograde conditions

Autor: Johann F.A. Diener, Chris Harris, Matt J. Ikari, Ake Fagereng, C. Stenvall

Faults that are active at retrograde conditions tend to contain metastable fault rock assemblages that are prone to undergo fluid-consuming reactions. These reactions typically lead to growth of minerals that are viscously and frictionally weaker tha

Sources and Effects of Fluids in Continental Retrograde Shear Zones: Insights from the Kuckaus Mylonite Zone, Namibia

Midcrustal rocks in retrograde metamorphic settings are typically H2O-undersaturated and fluid-absent and have low permeability. Exhumed continental retrograde faults, nonetheless, show evidence for the operation of fluid-mediated weakening mechanism

H2O-fluxed melting of eclogite during exhumation: an example from the eclogite type-locality, Eastern Alps (Austria)

Autor: Simon Schorn, Chris Harris, Michael I. H. Hartnady, Chris D. Clark, Johann F.A. Diener

Publikováno v: Lithos. :106118

Epidote eclogites embedded in paragneisses from the Austrian Eastern Alps host rare, decimetre- to metre-sized planar pegmatitic segregations (‘pegmatoids’) that consist of a hornblende–plagioclase–epidote–titanite–quartz assemblage. The

Origin and evolution of the ∼1.9 Ga Richtersveld Magmatic Arc, SW Africa

Autor: Christopher W. Lambert, C.A. Groenewald, H.M. Minnaar, Dirk Frei, P.H. Macey, C. Tinguely, Alexander F.M. Kisters, P.G. Gresse, P.J. le Roux, Robert J. Thomas, Johann F.A. Diener, J. Indongo, Jodie A. Miller, T. Dhansay, H. Smith, S. Doggart, M. Angombe, G. Shifotoka, Michael I. H. Hartnady

Publikováno v: Precambrian Research. 292:417-451

The results of a study of the Paleoproterozoic Richtersveld Subprovince/Magmatic Arc (RMA) in southern Namibia are integrated with previous work in adjacent NW South Africa to produce a new, unified model for the evolution of the RMA. The RMA was var
