Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.Abstract Detailed geochronology from two compositionally distinct generations of dikes and sills intruded into the Alta metamorphic aureole, north‐central Utah, complement previous geochronologic studies from the Alta stock, providing information on the timing of magmatism and the nature of emplacement.

Metamorphism and plutonism in the Quetico Belt, Superior Province, N.W. Ontario [PDF]
The Quetico Belt lies between the metavolcanic Wawa-Shebandowan and Wabigoon Belts. It consists of marginal metasedimentary rocks and central pelitic, gneissic and plutonic rocks.

A multidisciplinary study of a syntectonic pluton close to a major lithospheric-scale fault: relationships between the Montmarault granitic massif and the Sillon Houiller Fault in the Variscan French Massif Central. Part I: Geochronology, mineral fabrics and tectonic implications [PDF]
, 2007 International audienceDue to its location along one of the major faults, the Sillon Houiller Fault (SHF) of the French Massif Central (FMC), the Montmarault granitic pluton is well-suited to better understand the place of the late-orogenic magmatism in ...

A Rapid and Accurate Method for Estimating the Temperature Sensitivity of Soil Organic Matter (Q10)
European Journal of Soil Science, Volume 76, Issue 3, May–June 2025.ABSTRACT The carbon flux from soil organic matter degradation is significant and could increase with climate change, with a potential retroactive effect. The change in CO2 emissions from soils due to temperature variations can be estimated using the Q10 parameter, which measures how sensitive the rates of chemical reactions or biological processes are ...

Геодинамика и тектонофизика, 2017 In large igneous provinces (LIP) of fold areas, granitoid rocks are dominant, while mantle-derivated rocks play a subordinate role in rock formation. If magma emissions are impulsive, it may take 25–30 million years for a LIP to form and take shape.

Significance of Leucogranitic Gneiss in the Archean Teton Range
The UW National Parks Service Research Station Annual Reports, 2008 In previous years of this project, we have developed the hypothesis that the high-pressure granulites exposed in the Moose Basin area of the Teton Range represent evidence of a 2.7 billion yearÂold continent-continent collision. We have described gneisses in the Teton Range that show two distinct metamorphic histories. In the northwest there are highÂ

An investigation into the controls of granite plutonism in the Sierra da Freita region, Northern Portugal [PDF]
, 2012 The Serra da Freita region of north central Portugal was chosen for study as it displays the complex relationships between regional structure, plutonism, regional and contact metamorphism typical of this part of Iberia.

, 2006 International audienceThe emplacement of the Manaslu leucogranite body (Nepal, Himalaya) has been modelled as the accretion of successive sills. The leucogranite is characterized by isotopic heterogeneities suggesting limited magma convection, and by a ...
