Disruption of a high‐pressure unit during exhumation: Example of the Cycladic Blueschist unit (Thera, Ios and Naxos islands, Greece)

open access: yesJournal of Metamorphic Geology, Volume 42, Issue 2, Page 225-255, February 2024.
Abstract Reconstructing the original geometry of a high‐pressure tectonic unit is challenging but important to understand the mechanisms of mountain building. While a single nappe is subducted and exhumed, nappe‐internal thrusts may disrupt it into several subunits.

The Melting Mechanism of Hydrogen Direct Reduced Iron in Liquid Slag

open access: yessteel research international, Volume 95, Issue 1, January 2024.
An understanding of the underlying melting mechanisms of hydrogen direct reduced iron (H‐DRI) is essential in enabling the optimization of the fossil‐free process route. Correspondingly, the melting mechanism of H‐DRI in liquid slag is studied. When heated in liquid slag, the slag infiltrates the pore network of the H‐DRI.

Ocorrência da deficiência de magnésio em pimenta do reino (Piper nigrum L.) em condições de campo. [PDF]

open access: yes, 2016
Com a técnica de injeção foliar demonstra-se que a ocorrência de clorose amarelo-limão em folhas de pimenta do reino é devida à deficiência de magnésio. Os sintomas só ocorrem em plantas adultas, em produção, acentuando-se durante a fase de maturação dos

Redução da densidade de extrassístoles e dos sintomas relacionados após administração de magnésio por via oral

open access: yesArquivos Brasileiros de Cardiologia, 2012
FUNDAMENTO: As extrassístoles ventriculares e supraventriculares (EV e ESSV) são frequentes e muitas vezes sintomáticas. O íon magnésio (Mg) desempenha um papel importante na fisiologia do potencial de ação transmembrana celular e do ritmo cardíaco ...

Chromium in minerals as tracer of the polycyclic evolution of eclogite and related metabasite from the Pohorje Mountains, Slovenian Eastern Alps

open access: yesJournal of Metamorphic Geology, Volume 42, Issue 1, Page 63-88, January 2024.
Abstract Significantly different peak pressure–temperature (P–T) conditions (18–26 kbar and 630–760°C versus 29–37 kbar and 750–940°C) have previously been published for eclogite and related metabasites from the south‐eastern flank of the Pohorje Mountains in Slovenia. These rocks can show a bimodal distribution of chromium in the rock‐forming minerals,

Constraints on the Palaeoproterozoic tectono‐metamorphic evolution of the Lewisian Gneiss Complex, NW Scotland: Implications for Nuna assembly

open access: yesJournal of Metamorphic Geology, Volume 42, Issue 1, Page 109-142, January 2024.
Abstract Despite extensive investigation, the tectono‐thermal evolution of the Archean crust in the Lewisian Gneiss Complex in NW Scotland (LGC) is debated. Most U–Pb zircon geochronological and metamorphic studies have focused on rocks from the central region of the mainland LGC, where granulite facies assemblages associated with the oldest ...
