TLDR
The Palaeoproterozoic Waterberg Group consists mainly of a succession of coarse siliciclastic rocks which shows two upward-fining sequences as mentioned in this paper, and the main depository evolved as a continental, fault-bounded basin in the northern part of the Kaapvaal craton.About:

Precambrian clastic sedimentation systems
P.G. Eriksson,Kent C. Condie,Henrik Tirsgaard,Wulf Mueller,Wladyslaw Altermann,Andrew D. Miall,Lawrence B. Aspler,Octavian Catuneanu,Jeffrey R. Chiarenzelli +8 more
TL;DR: The unique and evolving nature of the Precambrian geological environment in many ways was responsible for significant differences between precambrian clastic sedimentary deposits and their Phanerozoic-modern equivalents as mentioned in this paper.

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.

Muddy Roll-up Structures in Siliciclastic Interdune Beds of the c. 1.8 Ga Waterberg Group, South Africa
Patrick G. Eriksson,Edward L. Simpson,Kenneth A. Eriksson,Adam John Bumby,George L. Steyn,Subir Kumar Sarkar +5 more
TL;DR: The Makgabeng roll-ups as discussed by the authors represent the oldest evidence for microbial colonisation of a terrestrial setting. But their alignment is considered to be the result of an extreme precipitation event, and they appear to have formed within a fully terrestrial paleoenvironment, in the oldest known Precambrian deserts.
Journal ArticleDOI
Precambrian continental freeboard and geological evolution: A time perspective
TL;DR: In this article, the authors examined the volcano-sedimentary record of a number of cratons: Kaapvaal, Singhbhum and Pilbara, and found that the geodynamic processes largely outweighed the tendency towards equilibrium.

Sedimentation patterns during the Precambrian : a unique record?
Pradip K. Bose,P.G. Eriksson,Subir Kumar Sarkar,David T. Wright,Pradip Samanta,Soumik Mukhopadhyay,Sunipa Mandal,Santanu Banerjee,Wladyslaw Altermann +8 more
TL;DR: In this article, the authors search for distinctiveness in the Precambrian sedimentary record, both siliciclastic and carbonate, through an extensive, though not exhaustive, review of the relevant literature augmented by new observations.

A review of the braided-river depositional environment
TL;DR: A review of more than sixty recent papers on modern and ancient braided-stream deposits can be found in this article, where several sedimentation models have been developed from a review of recent work.
Book
Origin of sedimentary rocks
TL;DR: In this paper, the origin of sedimentary rocks is discussed. And the authors propose a method to identify sedimentary sources and sedimentary sedimentary geysers in the Middle East.
MonographDOI
Depositional Environments as Interpreted from Primary Sedimentary Structures and Stratification Sequences
TL;DR: In this paper, the use of primary sedimentary structures and stratification sequence as tools for interpretation of depositional environment of clastic sediments is discussed, emphasizing advances in understanding that the authors judge to be important.
