Exhumation Mechanisms of High‐Pressure Rocks With High‐Temperature Overprinting: Insights From Eclogites of the Baie Verte Peninsula, Newfoundland

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT This study presents a comprehensive examination of exceptionally preserved eclogites from the Baie Verte Peninsula, Newfoundland Appalachians, which display a high‐temperature overprint, thus offering insights into the metamorphic evolution and exhumation mechanisms of such terrains. Through an integrated approach combining field observations,

Exhumed Serpentinites and Their Tectonic Significance in Non‐Collisional Orogens

open access: yesGeochemistry, Geophysics, Geosystems
Exhumed serpentinites are fragments of ancient oceanic lithosphere or mantle wedge that record deep fluid‐rock interactions and metasomatic processes. While common in suture zones after closure of ocean basins, in non‐collisional orogens their origin and

The Distribution of Major and Trace Elements Across a Garnet Population From the Kalak Nappe Complex (Finnmark, Scandinavian Caledonides): Evidence for Size‐Dependent Growth and Compositional Equilibration in the Garnet Zone

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT A garnet population from the lower Kalak Nappe Complex in Finnmark (Arctic Norway) was characterized using high‐resolution X‐ray micro‐computed tomography, electron probe micro‐analysis and laser ablation inductively coupled plasma mass spectrometry mapping to assess the extent of compositional equilibration and the controlling crystallization

Muscovites genetic types of gold ore and crystal-bearing deposits of the Urals

open access: yesЛитосфера, 2015
Mica of muscovite-fengite series are ones of the most important rock-forming minerals of metamorphic and metasomatic rocks in various metallic and nonmetallic deposits. The temperature and pressure significantly affects their composition, determining the

The Biological Horror of Capitalism

open access: yesSociology Lens, EarlyView.
ABSTRACT Karl Marx's masterpiece, Capital Vol. 1, was published in 1867. In it, he outlines the structure and nature of capitalism, as he saw it in capitalism's early period. This Perspectives article briefly thematically analyses Capital Vol. 1 and argues that in its threat to human health and well‐being, Marx viewed capitalism as a system of horror ...

Olivine-chrome-spinel equilibrium in chromitites and ultramafites of Rai-Iz massif, Polar Urals

open access: yesЛитосфера, 2016
Olivine and chrome-spinel compositions from chromitites and ore-bearing metamorphosed ultramafic rocks of Rai-Iz massif were compared. It was established that olivine and spinel ferruginosity are directly proportional and increase monotonically from ...
