Exhumation of Limpopo Central Zone granulites and dextral continent-scale transcurrent movement at 2.0 Ga along the Palala Shear Zone, Northern Province, South Africa
TLDR
The Palala Shear Zone is part of a major tectonic lineament in southern Africa, which extends over 1000 km from central Botswana to the Soutpansberg in South Africa as discussed by the authors.About:

1891–1883 Ma Southern Bastar–Cuddapah mafic igneous events, India: A newly recognized large igneous province
TL;DR: A newly recognized remnant of a Paleoproterozoic Large Igneous Province has been identified in the southern Bastar craton and nearby Cuddapah basin from the adjacent Dharwar craton, India as mentioned in this paper.

Archean Accretion and Crustal Evolution of the Kalahari Craton—the Zircon Age and Hf Isotope Record of Granitic Rocks from Barberton/Swaziland to the Francistown Arc
TL;DR: In this article, the results of laser ablation-sector field-inductively coupled plasma-mass spectrometry on zircon grains from 37 granitoid samples indicate that the Kalahari Craton consists of at least five distinct terranescBarberton South (BS), Barberton North (BN), Murchison^Northern Kaapvaal (MNK), Limpopo Central Zone (LCZ), and Francistownc, which underwent different crustal evolutions, and were successively accreted at c. 1.5 billion

Archaean to Proterozoic Crustal Evolution in the Central Zone of the Limpopo Belt (South Africa^Botswana): Constraints from Combined U^Pb and Lu^Hf Isotope Analyses of Zircon
TL;DR: In this paper, a combined set of U^Pb and Lu^Hf in situ laser ablation ICP-(MC)-MS zircon analyses were obtained from orthogneisses and granitoids in the Central Zone of the Limpopo Belt, which comprises the Beit Bridge and Mahalapye complexes.

Proterozoic geochronology and tectonic evolution of southern Africa
TL;DR: The Namaqua-Natal Belt defines a major convergent plate boundary active at this time along the southern margin of the Archaean Kaapvaal Craton, and the western part of this belt is inferred to link with a largely buried, NE-trending orogen present in the Kalahari region as mentioned in this paper.
Journal ArticleDOI
The Kaapvaal Craton and adjacent orogens, southern Africa: a geochronological database and overview of the geological development of the craton
TL;DR: In this article, a series of time-slice maps illustrating the development of the Kaapvaal Craton is presented, linking geochronological data to GIS coverages.

Non-ideal interactions in calcic amphiboles and their bearing on amphibole-plagioclase thermometry
Tjb Holland,Jon D Blundy +1 more
TL;DR: In this paper, amphibole thermodynamics are approximated with the symmetric formalism (regular solution model for within-site non-ideality and a reciprocal solution for cross-site terms) in order to formulate improved thermometers for amphibole-plagioclase assemblages.

An evaluation of criteria to deduce the sense of movement in sheared rocks
Carol Simpson,Stefan M. Schmid +1 more
TL;DR: In this paper, the most useful criteria for the determination of the sense of shear were summarized for use in areas where unequivocal field evidence is lacking and the use of quartz-crystallographic fabric asymmetry to deduce the shear sense in the bulk rock should be treated with caution and used only together with detailed microstructural observations.
Thermobarometry using multi-eouilibrium calculations: a new technioue, with petrological applications-
TL;DR: In this paper, an "internally consistent method" for performing thermobarometric calculations is described in which all possible equilibria implied by a given mineral assemblage are computed using an internally consistent set of thermodynamic data for end members and mixing propeilies.

TL;DR: The Kaapvaal craton of South Africa, which formed and stabilized between 3.7 and 2.7 Gyr ago, is one of the oldest reasonably sized examples of these continental fragments as mentioned in this paper.
