Massive chromitites of the Bushveld Complex, South Africa: A critical review of existing hypotheses
RM Latypov, SY Chistyakova, C Letsoele - Earth-Science Reviews, 2024 - Elsevier
The controversy over the origin of massive chromitites in layered intrusions has recently
become more contentious than ever before. At issue is whether they are produced via …

Dynamics of evolving magma chambers: textural and chemical evolution of cumulates at the arrival of new liquidus phases
Basaltic magma chambers are best exemplified by layered intrusions–fossilized natural
laboratories that historically constrain most fundamental principles of igneous petrology …

The formation of chromite chains and clusters in igneous rocks
MB Holness, Z Vukmanovic, B O'Driscoll - Journal of Petrology, 2023 - academic.oup.com
Crystal clusters are common in both extrusive and plutonic rocks, but the mechanisms by
which they form are not well-constrained. Following a consideration of the physics of …

Platinum-bearing chromite layers are caused by pressure reduction during magma ascent
Platinum-bearing chromitites in mafic-ultramafic intrusions such as the Bushveld Complex
are key repositories of strategically important metals for human society. Basaltic melts …

Fossilized solidification fronts in the Bushveld Complex argue for liquid-dominated magmatic systems
Chemical differentiation of magma on Earth occurs through physical separation of liquids
and crystals. The mechanisms of this separation still remain elusive due to the lack of …

Chromitite layers indicate the existence of large, long-lived, and entirely molten magma chambers
The classical paradigm of the 'big magma tank'chambers in which the melt differentiates, is
replenished, and occasionally feeds the overlying volcanos has recently been challenged …

Monomineralic anorthosites in layered intrusions are indicators of the magma chamber replenishment by plagioclase-only-saturated melts
The formation of some Earth's monomineralic igneous rocks appears to be prohibited by
constraints imposed by liquidus phase-equilibria on evolution of mantle-derived magmas …

Distribution of platinum-group elements in pristine and near-surface oxidized Platreef ore and the variation along strike, northern Bushveld Complex, South Africa
Abstract The Platreef of the Bushveld Complex is currently the largest PGE open pit deposit.
In order to investigate the behavior of PGE during weathering, three boreholes covering a …
