Layered intrusions: Fundamentals, novel observations and concepts, and controversial issues

RM Latypov, O Namur, Y Bai, SJ Barnes… - Earth-Science …, 2023 - Elsevier
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) …

Chromium speciation and mobility in contaminated coastal urban soils affected by water salinity and redox conditions

P Sricharoenvech, MG Siebecker, R Tappero… - Journal of Hazardous …, 2024 - Elsevier
Chromium (Cr) is a redox-sensitive element in contaminated coastal urban soils. Sea level
rise (SLR) with subsequent soil inundation may facilitate Cr transformation and mobilization …

Genesis of the peridotite zone, Stillwater Complex, Montana, USA

MC Jenkins, JE Mungall - Journal of Petrology, 2018 - academic.oup.com
Here, we critically examine models for the development of layering in the ultramafic rocks of
the Stillwater Complex of Montana, USA. A fine-grained, high-magnesium (high-Mg) dike in …

Fossilized solidification fronts in the Bushveld Complex argue for liquid-dominated magmatic systems

W Kruger, R Latypov - Nature Communications, 2020 - nature.com
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 …

In situ crystallization of non-cotectic and foliated igneous rocks on a magma chamber floor

W Kruger, R Latypov - Communications Earth & Environment, 2022 - nature.com
Layered mafic intrusions commonly contain non-cotectic, foliated igneous rocks that are
traditionally attributed to processes involving settling, transport, and redeposition of crystals …

Chromitite layers indicate the existence of large, long-lived, and entirely molten magma chambers

R Latypov, S Chistyakova, SJ Barnes, B Godel… - Scientific Reports, 2022 - nature.com
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

R Latypov, S Chistyakova, G Costin, O Namur… - Scientific Reports, 2020 - nature.com
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 …

Experimental study on the effects of H2O upon crystallization in the Lower and Critical Zones of the Bushveld Complex with an emphasis on chromitite formation

IV Veksler, T Hou - Contributions to Mineralogy and Petrology, 2020 - Springer
Mafic–ultramafic layered rocks of the Lower and Critical Zones of the Bushveld Complex are
believed to have formed from a parental magma usually labelled B1 with SiO 2 content at 55 …

Distribution of platinum-group elements in pristine and near-surface oxidized Platreef ore and the variation along strike, northern Bushveld Complex, South Africa

M Junge, T Oberthür, D Kraemer, F Melcher, R Piña… - Mineralium …, 2019 - Springer
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 …
