...N. Hicks; D.J.C. Gold; M. Ncume; L. Hoyer Abstract A revised lithostratigraphic framework for Mozaan Group-equivalent strata within the Nkandla sub-basin is presented based on new field data, remote sensing and genetic sequence stratigraphic interpretations. Although previous literature has...

.... Amphibolites were derived from the metamorphism of tholeiitic basalts characterized by geochemical signatures similar to those of volcanic rocks of the nearby Pongola Supergroup. Quartzites are compositionally similar to sandstones from the Mozaan Group. LA-ICP-MS U-Pb analysis of zircon grains from grey...

... was the Denny Dalton Mine which operated sporadically between 1893 and 1926. Thin beds of gold-and uranium-bearing conglomerate are locally present in the Denny Dalton area, at the base of the Mozaan Group in the Sinqeni Formation. The conglomerates share similarities to those of the Witwatersrand goldfields...

... life. In this contribution, we report multiple-sulfur ( 33 S/ 32 S, 34 S/ 32 S, and 36 S/ 32 S) isotope ratios of sulfide minerals and carbon ( 13 C/ 12 C) isotope ratios of organic carbon for shale in the ~2.96 to ~2.84 Ga Mozaan Group of the Pongola Supergroup, Southern Africa. The δ 13 C of organic...

...Nora Noffke; Robert Hazen; Noah Nhleko Abstract This study provides evidence for the existence of filamentous (cyano-) bacteria forming sediment-stabilizing mats in shelf environments at 2.9 Ga—the oldest known occurrence of microbial mats in siliciclastic rocks. The Mesoarchean Mozaan Group, South...

...J. Gutzmer; N. Nhleko; N. J. Beukes; A. Pickard; M. E. Barley Abstract The Mozaan Group of the Pongola Supergroup is one of the oldest known cratonic supracrustal successions in the world. In the Mooihoek area, south central Swaziland, the Mozaan Group is preserved in an open syncline with axial...

...Figure 18 Lithostratigraphic section of the Mozaan Group as intersected in 1740 m deep drill core PNG4 near Nongoma (see Figure 1 for position). A spinifex-textured ultramafic unit is present near the base of the succession. Other important rock units include felsic breccias and an ultramafic...

... Nsuze and ca. 2.9 Ga Mozaan Groups (Pongola Supergroup) of south-central Eswatini and northern KwaZulu-Natal province have slightly enriched compositions compared to the newly sampled Kubuta volcanic rocks. Our results suggest that the Nsuze and Mozaan Groups were sourced from a primitive mantle...

...N. Hicks; D.J.C. Gold Abstract The Mesoarchaean Sinqeni Formation forms the lowermost unit of the predominantly sedimentary Mozaan Group (Pongola Supergroup) of southern Africa. The formation comprises a dominantly arenaceous succession, which can be subdivided into four members. A laterally...

... in different magma chambers, can explain the difference between the two signatures of the Bird Member. Finally, despite previous proposals for stratigraphically correlating the Witwatersrand Supergroup to the Mozaan Group of the Pongola Supergroup, their volcanic units are overall geochemically distinct. e...
