The low-pressure partial-melting behaviour of natural boron-bearing metapelites from the Mt Stafford area, Central Australia
(Stellenbosch : University of Stellenbosch, 2011-12)
ENGLISH ABSTRACT: This study has examined the 3 kbar partial melting behaviour of 4 metapelites collected from the highest grade rocks occurring below the anatectic zone of the Mt Stafford area, Arunta Inlier, central ...
The processes of melt segregation, magma ascent and pluton emplacement in the continental crust of the Damara Belt, Namibia
(Stellenbosch : Stellenbosch University, 2016-03)
ENGLISH ABSTRACT: Theoretical models of meso- and macroscale granitic melt/magma transport commonly invoke a prominent role for dilatant fracturing of the wall rocks, but supporting field evidence is in many cases only ...
Geology, structural evolution and controls of hydrothermal gold mineralization in the Eastern Karagwe-Ankole fold belt, North Western Tanzania
(Stellenbosch : Stellenbosch University, 2016-03)
ENGLISH ABSTRACT: In central-east Africa, the north-western margin of the Archaean Tanzania Craton (TC) is overlain by imbricated, low grade, volcano-sedimentary rocks of the Karagwe-Ankole belt’s (KAB) Eastern Domain (ED). ...
Bulk geochemical, biomarker and leaf wax isotope records of Mfabeni peatland, KwaZulu Natal, South Africa since the late Pleistocene
(Stellenbosch : Stellenbosch University, 2016-03)
ENGLISH ABSTRACT: Southern Africa is a topographically diverse region that is influenced by temperate, sub-tropical and tropical climates encompassing varying rainfall zones. The core regional contemporary climatic drivers ...
The formation of Earth’s early felsic continental crust by water-present eclogite melting
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: The sodic and leucocratic Tonalite, Trondhjemite and Granodiorite (TTG) granitoid series of
rocks characterise Paleo- to Meso- Archaean felsic continental crust, yet are uncommon in the
post-Archaean ...
Repeated partial melting events in the polymetamorphic Carlos Chagas batholith : implications for the tectono-metamorphic evolution of the Araçuaí orogen (southeastern Brazil)
(Stellenbosch : Stellenbosch University, 2017-03)
ENGLISH ABSTRACT: The Araçuaí orogen (AO), located in the southeastern Brazil, and its African counterpart, the West Congo
belt, is part of the Pan-African-Brasiliano orogenic system developed between the Congo and São ...
Differentiation and stabilisation of the Archean continental crust, the example of the northern edge of the Kaapvaal craton, South Africa
(Stellenbosch : Stellenbosch University, 2017-03)
ENGLISH ABSTRACT: The Earth is one of the only solid celestial bodies displaying, at present day, an internal activity significant enough to modify its surface. This activity is mostly pictured by plate tectonic motions, ...
Genesis and evolution of a Neoproterozoic magmatic arc: the cordilleran-type granitoids of the Araçuaí Belt, Brazil.
(Stellenbosch : Stellenbosch University, 2018-12)
ENGLISH ABSTRACT: The Araçuaí orogen (SE Brazil) is one of the largest (350,000 km2) and long-lived (ca. 630 – 480
Ma) granitic province in the world. Its wide variety of granitoids recording mid- to lower crustal P -
T ...
Using distributive surface water and groundwater modelling techniques to quantify groundwater recharge and baseflow for the Verlorenvlei estuarine system, west coast, South Africa.
(Stellenbosch : Stellenbosch University, 2018-12)
ENGLISH ABSTRACT: For effective management of groundwater resources, recharge rates and baseflow volumes need to be quantified to determine sustainable abstraction regimes and to quantify the ecological reserve, the amount ...
Geological setting and evolution of the Omitiomire Cu deposit in the Southern Zone accretionary prism of the Damara Belt, Namibia
(Stellenbosch : Stellenbosch University, 2017-12)
ENGLISH ABSTRACT: Shear Zone hosted Cu mineralisation in the Deep Level Southern Zone accretionary prism of the Damara Belt is associated with deformation and fluid flow related to the exhumation of the Mesoproterozoic ...
