U–Pb Dating of Cambrian Magmatism in the Pinerolo‐Sanfront Unit, Dora‐Maira Massif (Western Alps)

Terra Nova, EarlyView.
ABSTRACT The Pinerolo‐Sanfront Unit (PSU), the structurally lowest tectonic unit of the Dora‐Maira Massif (Western Alps), has been regarded as a monocyclic unit composed of Permo‐Carboniferous sediments and Permian granitoids that were metamorphosed during the Alpine orogeny.

Multi‐Mineral Geochronology Across the Neoproterozoic Brasília Nappe Stack: Constraints on Thermal Resetting and Metamorphic Architecture

Terra Nova, EarlyView.
ABSTRACT The Southern Brasília Orogen formed during Western Gondwana's final assembly and comprises nappe systems piled against the São Francisco Craton. We present new rutile U–Pb ages from the lowermost Canastra Group (> 2.2 Ga) and the uppermost Carrancas Group (~560 Ma), integrated with published zircon, monazite, garnet, and mica ages from the ...

Experimental Evidence for a Weak Calcic‐Amphibole‐Rich Deep Crust in Orogens

Geophysical Research Letters, 2023
Amphibole‐rich rocks constitute significant components of the mid‐ to lower continental crust, particularly in active orogens characterized with thick and hot crusts. Nevertheless, experimental data on their viscosity remain scarce.

Tectonics on Early Earth Driven by Earth's Changing Shape During Tidal Recession of the Moon

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Few fragments of Earth's earliest crust have survived, and so this formative period of our planet's history is shrouded in mystery. To leverage the limited data available, it is important to understand all the processes that could have shaped our young planet.

Is the garnet amphibolite in the Longyou a retrograded eclogite? [PDF]

Chinese Science Bulletin, 2015
A paper titled as “Retrograde garnet amphibolite from eclogite of the Zhejiang Longyou area: New evidence of the Caledonian orogenic event in the Cathaysia block” was recently published in Chinese Science Bulletin (Chen et al., 2015). However, the petrographic features and mineral compositions that authors provided cannot demonstrate that high ...

A Geophysical Crustal Model of Central Italy for Geoneutrino Predictions in Borexino

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Predicting the geoneutrino signal at underground detectors requires a local crustal reference whose precision matches the experimental uncertainty. The current Borexino reference is 15 years old and deterministic. We replace it with GUESS, a probabilistic 3‐D model of the Gran Sasso region, built by Bayesian inversion of multi‐source ...
