The Wilson Cycle of the North Altyn Ocean: A Record of Subduction Initiation, Slab Rollback, and Final Closure

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The North Altyn ophiolitic belt was formed by the subduction–closure of the Altyn segment of the Proto–Tethys Ocean and recorded the accretion of Tarim to northern Gondwana, but the timing of initial subduction and detailed tectonic transition processes remain poorly constrained. This study reports the oldest Phanerozoic magmatic record of 537

U-Th-Pb and Hf isotopic data on zircon and apatite of non-granulite rocks from the Saxonian Granuilite Massif

open access: yes
The geology of the Saxon Granulite Massif and particularly its metamorphic history is a matter of on-going (passionate) discussions that resulted in several concurring tectonic models.

DEEP CRUSTAL STRUCTURE AND MODEL OF NEORCHAEAN EVOLUTION OF THE NORTH AMERICAN CRATON

open access: yesГеодинамика и тектонофизика, 2018
The structure of the Archaean crust of the North America has been studied based on the synthesis of geolo‐ gical and geophysical data, including seismic sections along LITHOPROBE Geotransects, magnetic and gravity anomaly maps, and seismic tomography ...

Investigations of garnets from polymetamorphic rocks of the Lapland Granulite Belt of the Kandalaksha Region

open access: yes, 2015
Introduction: The Lapland Granulite Belt is placed on the Kandalaksha region (Kola Peninsula, Russia). The rocks of this Belt are composed mainly of amphibolites and granulites.

An Analysis of an Appalachian Metamorphic Suite [PDF]

open access: yes, 2011
The Blue Ridge is one of over a dozen provinces located in the much larger Appalachian Mountain Range which spans across the eastern United States. The Appalachian Mountains began to form close to 500 million years ago and rocks within the Blue Ridge ...

How High Are the P-T Conditions for Paleoproterozoic Metamorphism of the Huangtuling Felsic Granulite, North Dabieshan, Central China?

open access: yes, 2006
The 2. 34 cm-wide garnet porphyroblast in the Paleoproterozoic felsic granulite from the Huangtuling area, North Dabieshan, has been reinvestigated for compositional variation in light of Cacomposition X-ray mapping to obtain peak P-T conditions of ...

Constraining the Protoliths of the Apollo Granulite Suite

open access: yesThe Planetary Science Journal
The Apollo granulite suite represents the metamorphosed products of impact-contaminated polymict and monomict lunar breccias. We combine bulk and mineral major and trace element systematics with noble gas isotopes to constrain the highland lithologies ...

ARCHEAN AND PALEOPROTEROZOIC HISTORY OF ROCK METAMORPHISM IN THE URALS CRUSTAL SEGMENT

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
In the Urals, Archean and Paleoproterozoic formations were found in several polymetamorphic complexes which crop out as relatively small tectonic blocks (within the first thousands sq. km in area).
