Development of the Platreef in the northern limb of the Bushveld Complex at Sandsloot, Mokopane District, South Africa
… the base of the Rustenburg Layered Suite in the northern limb of the Bushveld Complex. The reef lies unconformably on a footwall (floor) sequence of Transvaal Supergroup sedimentary rocks and Archaean granite/gneiss basement, and is overlain by a hangingwall (roof) of Main Zone gabbronorites. …

The use of sulfide mineral chemistry to understand PGE mineralization processes in the Northern Limb of the Bushveld Igneous Complex
… lithological unit defining the base of the Northern Limb of the Bushveld Igneous Complex (BIC) and typically characterized by complex magma-footwall interaction. It is of interest primarily because it contains significant PGE-Ni-Cu mineralization and there is no consensus regarding the …

Assessing the extent of local assimilation within the Platreef, Northern Limb of the Bushveld Igneous Complex, using sulfur isotopes and trace element geochemistry
… to metasedimentary footwall units in the Northern Limb of the Bushveld Igneous Complex (BIC) has resulted in a complex local contamination of in this maficultramafic intrusive body, including the units containing platinum group element (PGE) mineralization. To assess the extent of …

The Application of Machine Learning Methods to Portable X-Ray Fluorescence Data: A Case Study from Zwartfontein Farm, Northern Limb of the Bushveld Complex, South Africa
… of methods was tested, as a case study, on the Northern Limb of the Bushveld Complex of South Africa – a complex multi-commodity deposit (Ni-Cu-(Co)-PGE) comprising intricately layered mafic-ultramafic cumulate rocks overprinted by variable alteration minerals. Although pXRF provides rapid …

Structural Characteristics and Tectonic Evolution of the Pirineus Syntaxis, Central Brazil
… of two distinct fold-thrust belts. The southern limb of syntaxis consists of an east-verging fold-thrust belt in which spoon-shaped thrust sheets, bordered by lateral ramps, are arrayed in an imbricate fan. These thrust sheets consist of continental-margin strata of the Araxa, Canastra and …

Numerical model investigation of near-surface circulation features of the Angola Basin
… is associated with the Model Dome. However, the northern limb is unequivocally coincident with the South Equatorial Undercurrent (SEUC) at 2-5"S and the South Equatorial Countercurrent (SECC) at 10·S. Upon reaching the African coast, the SEUC and SECC bend poleward to form the southward Angola …

Surface characterisation and flotation behaviour of the platinum and palladium arsenide, telluride and sulphide mineral species
The Platreef is located in the northern limb of the Bushveld Complex of South Africa. This reef consists of a complex assemblage of rock types, with pyroxenites, serpentinites and calcsilicates being the most abundant. The predominant PGMs are the tellurides, arsenides, alloys and sulphides. The Pt …

Paleomagnetic Constraints on Assembly of the Superior Craton: Results from the 2.72-2.69 Ga Vermilion District of the Wawa Subprovince, MN
… depending on locality: samples from the southern limb of an anticline host a direction D, I = 165.82°, -70.23° (α₉₅ = 14.4°; n= 2 VGPs), while those from the northern limb host D, I = 198.5°, 78.85° (α₉₅ = 14.0°; n = 5 VGPs). To understand the relative timing of these magnetization directions, we …
