[HTML][HTML] Layered intrusions: Fundamentals, novel observations and concepts, and controversial issues

RM Latypov, O Namur, Y Bai, SJ Barnes… - Earth-Science …, 2024 - Elsevier
Layered intrusions are fossilized natural laboratories that historically have constrained many
fundamental principles of igneous petrology. Layered intrusions are typically stratiform …

Orogenic gold: is a genetic association with magmatism realistic?

RJ Goldfarb, I Pitcairn - Mineralium Deposita, 2023 - Springer
Many workers accept a metamorphic model for orogenic gold ore formation, where a gold-
bearing aqueous-carbonic fluid is an inherent product of devolatilization across the …

Water availability controls crustal melting temperatures

WJ Collins, JB Murphy, E Blereau, HQ Huang - Lithos, 2021 - Elsevier
Although the capacity for water to lower the solidus during crustal melting is well recognised,
a modern consensus is that most granitic magmas are generated under fluid-absent melting …

Fluid–mineral interactions: controlling coupled mechanisms of reaction, mass transfer and deformation

A Putnis - Journal of Petrology, 2021 - academic.oup.com
Fluid–rock interaction has profound effects on the dynamics of the lithosphere. This
Perspectives article describes the catalytic effects of water on the kinetics of mineral …

Thermal constraints on the longevity, depth, and vertical extent of magmatic systems

AF Glazner - Geochemistry, Geophysics, Geosystems, 2021 - Wiley Online Library
Magmatic regions are typically viewed as vertical systems, with magma coming in the bottom
and either freezing in the crust to form plutons or erupting to form volcanic rocks. Maintaining …

Modeling water exsolution from a growing and solidifying felsic magma body

C Annen, A Burgisser - Lithos, 2021 - Elsevier
We modeled water exsolution from a growing and crystalizing felsic magma body using a
conductive thermal model with simplified physical mechanisms of volatile transport. Magma …

Magma Chamber Formation by Dike Accretion and Crustal Melting: 2D Thermo‐Compositional Model With Emphasis on Eruptions and Implication for Zircon Records

OE Melnik, IS Utkin, IN Bindeman - Journal of Geophysical …, 2021 - Wiley Online Library
We present a 2D thermo‐elastic model of a magma body formation in a granitic crust by
injection of rhyolitic or basaltic dikes and sills. Elastic analytical solutions enable the …

Picking up the hydrothermal whisper at Ischia Island in the Covid-19 lockdown quiet

M Falanga, P Cusano, E De Lauro, S Petrosino - Scientific Reports, 2021 - nature.com
In this paper, we analyse the seismic noise at Ischia Island (Italy) with the objective of
detecting the hydrothermal source signals taking advantage of the Covid-19 quiescence due …

Snapshots of magmatic evolution revealed by zircon depth profiling

EJ Schoonover, MR Ackerson, JM Garber… - Earth and Planetary …, 2024 - Elsevier
Upper-crustal granitoids are a late-stage product of crustal differentiation. This last stage in
the evolution has been proposed to be the key interval that governs volcanic eruptions, ore …

High-temperature alteration during cooling of mafic intrusions: Insights from the Saint-Jean-du-Doigt intrusive complex (Armorican Massif, France)

A Pochon, G Iacono-Marziano, E Gloaguen, J Tuduri… - Lithos, 2023 - Elsevier
We characterize the alteration of the Saint-Jean-du-Doigt mafic-dominated, bimodal
intrusive complex in the Armorican Massif by means of petrographic investigation and …
