Can Multiphase Inclusions in Garnet From Eclogite Facies Rocks Be a Product of Melt or Supercritical Fluid Entrapment During Subduction?

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Dehydration of rocks and minerals during high‐pressure metamorphism is controlled by the thermal structure of the subduction zone and can be traced by the stability fields of hydrous phases. Consistent with the results of experimental works, the content of silicate components in fluids is assumed to increase from the fields of subcritical to ...

The Piedmont Zone From the Western Alps (Italy): New Insights From High‐Pressure Ophiolitic Metasediments in the Soana Valley

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Metaophiolites and metasediments of the Piedmont Zone are exposed in the Soana Valley, a poorly studied area of the Western Alps, located between the Europe‐related Gran Paradiso massif and the Adria‐related Sesia–Lanzo zone. Previous investigations reported the occurrence of only greenschist‐facies metamorphic assemblages in the metasediments.

Permian-Triassic basalts from basement of the West Siberian basin from superdeep hole Yen-Yakhinskayа SG-7

open access: yesЛитосфера, 2016
For the first time detailed mineralogical research of the Permo-Triassic basalt core samples of Yen-Yakhinskaya superdeep hole SG-7 from the depths of 7673 m, 8009 m and 8250 m was carried. The composition of minerals investigated.

Temperature effects on compensatory responses in an early spring‐breeding amphibian

open access: yesJournal of Zoology, EarlyView.
To better understand how phenological shifts may affect organisms with complex life histories as well as effects across life stages, we experimentally evaluated larval wood frog (Rana sylvatica) responses to hatching phenology and increased pond temperatures.

Implications of Surface Heat Flux for Shear Stress and Temperature on the Plate Interface Beneath Northern Honshu

open access: yesGeochemistry, Geophysics, Geosystems
Measurements of surface heat flux from boreholes of the NIED Hi‐net network of seismometers are used to determine temperature and shear stress on the plate interface beneath northern Honshu.

Nature and origin of fluids in granulite facies metamorphism [PDF]

open access: yes
The various models for the nature and origin of fluids in granulite facies metamorphism were summarized. Field and petrologic evidence exists for both fluid-absent and fluid-present deep crustal metamorphism.

Plate Tectonics and Metamorphism: Teaching Complex Systems Using Videos and Animations

open access: yesGeosciences
Metamorphism is a complex geologic process that is often poorly covered in introductory geology courses. This study explores the effectiveness of a video-based instructional intervention in improving student understanding of metamorphism and its ...
