[HTML][HTML] Layered intrusions: Fundamentals, novel observations and concepts, and controversial issues
Layered intrusions are fossilized natural laboratories that historically have constrained many
fundamental principles of igneous petrology. Layered intrusions are typically stratiform …

The geotectonic setting, age and mineral deposit inventory of global layered intrusions
WD Smith, WD Maier - Earth-Science Reviews, 2021 - Elsevier
In the present paper, we have compiled data on 565 layered and differentiated igneous
intrusions globally, documenting their (i) location,(ii) age,(iii) size,(iv) geotectonic setting,(v) …

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 …

A novel hypothesis for origin of massive chromitites in the Bushveld Igneous Complex
The origin of chromitites in the Bushveld Complex has been attributed to two principal
mechanisms:(1) gravity-controlled settling of chromite onto the chamber floor from magma …

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 …

Morphology and particle size distribution of olivines and sulphides in the **chuan Ni–Cu sulphide deposit: evidence for sulphide percolation in a crystal mush
The **chuan intrusion is the largest single magmatic nickel sulphide deposit in the world.
Sulphide mineralization mainly occurs in two segments (I and II). The crystal size …
