Magnetotelluric measurements across the southern Barberton Greenstone Belt, South Africa
Der Barberton Grünsteingürtel (BGB) in Südafrika gehört zu den wenigen Regionen mit noch gut erhaltener Archaischer Kruste. Seit Jahrhunderten wurde der BGB eingehend untersucht und seine geologischen und tektonischen Strukturen detailliert kartiert. Über die tiefere Struktur des BGB ist hingegen …

Aspects of the geochemistry of Onverwacht Group lavas from the Barberton Greenstone Belt
… and tholeiitic lavas in the Onverwacht Group (Barberton greenstone belt) crop out in the rugged terrain of the eastern Transvaal lowveld. The results of an investigation into the geochemistry of the lavas, mainly from the three lower Formations of the Onverwacht Group - the Lower Ultramafic …

Structural, geophysical and geochemical characterisation of a Mesoarchean paleosuture zone, Barberton Greenstone Belt, South Africa
… conductivity of the subsurface below the Barberton Greenstone Belt (BGB) reveal two electrically conductive zones that extend to a depth of at least 5km. These high conductivity zones correlate well with regional shear zones geologically mapped at surface. The serpentinised Stolzburg …

A stable isotope study of the Kaap Valley Tonalite, Barberton Mountain Land, South Africa
… of hydrous minerals occur along the KVT and Barberton greenstone belt contact zone, and along major shear zones within the KVT.

Determining the physico-chemical conditions on the early earth : Barberton scientific drilling project, South Africa
… most of the ca. 3.5-3.2 Ga, Paleoarchean Barberton Greenstone Belt (BGB) of South Africa. However, PT-constraints and detailed petrological information on the variably altered mafic-ultramafic rocks are sparse and the nature of greenschist facies metamorphism is poorly characterized. In …

Arsenic dispersion associated with the Barbrook gold mine in the Mpumalanga Province of South Africa
… gold deposits associated with the Barberton greenstone belt, located in the Mpumalanga province of South Africa, have been mined on various scales since late last century. The Barbrook mine is located close to the Swaziland border in an area of the Barberton mountainlands which …

Trace Element Geochemistry of Compositionally Layered Impact Spherules
… spherules from the S3 spherule layer in the Barberton Greenstone Belt (BGB) in the Kaapvaal Craton of South Africa focuses on the heterogeneity of textures and geochemistry produced during the cooling and crystallization of spherules within a vapor plume. Type 4b spherules are layered …

Functional characterisation of ScIRT1 and ScIREG2 transport proteins in the nickel hyperaccumulator, Senecio coronatus
… can be found on the serpentine soils of the Barberton Greenstone Belt, South Africa. A comparative RNA-seq analysis on these populations of S. coronatus revealed that ScIRT1 and ScIREG2 , putative homologues of the Arabidopsis transporters, AtIRT1 and AtIREG2 which are capable of transporting …

Petrogenesis of Mesoarchean high-K rocks in the Kaapvaal Craton: Investigating the Boesmanskop Alkaline Complex and Salisbury Kop batholith
… of small intrusions at the southern end of the Barberton greenstone belt, recording shear deformation and containing the most potassic and REE-rich rocks of the GMS suite. In contrast, the SB is a homogeneous batholith at the north of the belt with a more sodic character. This study examines the …

Tektono-metamorphe Kontrolle der archaischen Goldmineralisation in der New Consort Gold Mine, Barberton Grünsteingürtel, Südafrika
… Consort Gold Mine in the Palaeo- to Mesoarchaean Barberton greenstone belt, South Africa, is one of the oldest recognized orogenic gold deposits on Earth. The gold mineralization is hosted by discrete mylonitic units, the so-called Consort Bar, which occurs at the contact between the c. 3280-3260 …
