TLDR
The results of point counting, major and trace element geochemistry, and U-Pb detrital zircon geochronology indicate that the Waterberg sedimentary formations in the study area were primarily sourced by siliceous (rifted margin) sedimentary and minor mafic volcanic rocks of the Archean Beit Bridge Complex, Limpopo Central Zone as discussed by the authors.About:

Paleoproterozoic I-type granites and their implications for the Yangtze block position in the Columbia supercontinent: Evidence from the Lengshui Complex, South China
TL;DR: In this paper, an integrated study of major and trace element data, SHRIMP and LA ICP-MS zircon U-Pb age data, and Hf isotopic data for the granites from the Lengshui Complex in the northern Yangtze Block is reported.

The role of U-Pb ages of detrital zircons in sedimentology-An alarming case study for the impact of sampling for provenance interpretation
TL;DR: In this article, U-Pb LA-ICP-MS analysis on detrital zircons from two samples of Cambrian age (Herreria Formation, Cantabrian Mountains, Spain) revealed very different provenance signatures at the base and top of the formation.
Journal ArticleDOI
Successive sedimentary recycling regimes in southwestern Gondwana: Evidence from detrital zircons in Neoproterozoic to Cambrian sedimentary rocks in southern Africa
TL;DR: In this paper, detrital zircon data from the Gariep, Saldania and Damara Belts and the Nama Group of South Africa and Namibia, which were deposited between ca. 750 and ca. 550 Ma, have been used to trace the trace of detritus in a deposit from source to sink.

New U–Pb geochronologic and palaeomagnetic constraints on the late Palaeoproterozoic Hartley magmatic event: evidence for a potential large igneous province in the Kaapvaal Craton during Kalahari assembly, South Africa
Farnaz Alebouyeh Semami,Michiel O. de Kock,Ulf Söderlund,Ashley Gumsley,Richard da Silva,N.J. Beukes,Richard Armstrong +6 more
TL;DR: In this paper, the age and palaeopole of the Hartley Formation were derived for the mafic and felsic phases of a large-scale 1.93-1.91-Ga bimodal magmatism on the Kaapvaal Craton.

Zircon ages defining deposition of the Palaeoproterozoic Soutpansberg Group and further evidence for Eoarchaean crust in South Africa
TL;DR: The Soutpansberg Group is subdivided into a lower and upper succession, which are separated from each other by a prominent regional unconformity as mentioned in this paper, and the oldest zircon grains have rounded shapes, however it is not clear whether they are mainly xenocrystic or detrital and have been rounded by resorption in a silicic magma chamber.

Paleoproterozoic intraplate magmatism and basin development on the Kaapvaal Craton: Age, paleomagnetism and geochemistry of ~1.93 to ~1.87 Ga post-Waterberg dolerites
Richard E. Hanson,Wulf A. Gose,James L. Crowley,Jahandar Ramezani,Samuel A. Bowring,D. Bullen,R.P. Hall,James A. Pancake,Joshua Mukwakwami +8 more
TL;DR: Pb baddeleyite crystallization ages of ~1927 and ~1879 to ~1872 Ma for dolerite sills intruding the Waterberg Group in Botswana and South Africa were reported in this article.

Undulatory extinction in quartz of igneous and metamorphic rocks and its significance in provenance studies of sedimentary rocks
Harvey Blatt,John M. Christie +1 more
TL;DR: In this article, the authors evaluated the use of undulatory extinction and polycrystallinity in detrital quartz grains for the determination of provenance of sediments, and concluded that the presence or absence of non-undulatory quartz grains in a sedimentary rock robably indicates that the assemblage of grains has passed through several sedimentary cycles, rather than derivation from either plutonic igneous or metamorphic source rocks.

The Triangle Shearzone, Zimbabwe, revisited: new data document an important event at 2.0 Ga in the Limpopo Belt
TL;DR: In this article, the authors studied the age and PT conditions of strike-slip tectonism along the important right-lateral triangle shearzone and showed that the Triangle Shearzone can now be regarded as an important Proterozoic suture.

Greg H. Mack,Keith A. Rasmussen +1 more

Himalayan-Tibetan analogies for the evolution of the Zimbabwe Craton and Limpopo Belt
TL;DR: The Limpopo Orogeny as mentioned in this paper is characterised by NNW-SSE directed shortening, which resulted in both crustal thickening, accommodated by folding and NNWdirected thrusting, and associated crustal extrusion whereby a number of crustal blocks, including the Central Zone of the Limpopa Belt, was displaced to the west-southwest along WSW-ENE trending shear zones.
