The Roles of Climate and Tectonics in the Tectonomorphic Evolution of the Sagarmatha (Mt. Everest) Region, Eastern Nepal Himalaya

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract To understand the interplay of climate and tectonics in driving long‐term erosion and landscape evolution in the Himalayan orogen, this study examines the tectono‐thermal evolution of the Sagarmatha (Mt. Everest)‐Rolwaling‐Okhaldhunga region in eastern Nepal.

Variations in the P‐T‐t of Deformation in a Crustal‐Scale Shear Zone in Metagranite

Geochemistry, Geophysics, Geosystems, 2020
Deformation in crustal‐scale shear zones occurs over a range of pressure‐temperature‐time (P‐T‐t) conditions, both because they may be vertically extensive structures that simultaneously affect material from the lower crust to the surface, and because ...

Syn-convergence flow inside and at the margin of orogenic plateaus: Lithospheric-scale experimental approach [PDF]

, 2015
International audienceThis study investigates three-dimensional flow modes of orogenic plateaus by means of physical modeling. Experiments consist of shortening two contiguous lithospheres of contrasting strength, one being a weak plateau-type ...

A zircon petrochronologic view on granitoids and continental evolution

Earth and Planetary Science Letters, 2020
Abstract Temporal trends in granitoid chemistry and thermometry constrain major global changes in magmatism, tectonism or crustal thickness in the continents. Our study relies on zircon geochronology and trace element geochemistry on four new detrital rocks (two modern sediments and two Archean metasedimentary rocks) and a global compilation of ...

High-P metamorphism in the Mesoproterozoic: Petrochronological insights from the Grenville Province

Precambrian Research, 2023
In the Grenville Province, high-P rocks that are discontinuously exposed along the margin of the allochthonous belt preserve the record of deep crustal processes and are an essential puzzle piece to understanding Mesoproterozoic geodynamics. The Manicouagan Imbricate zone (MIZ) is one of the three high-P domains from the Grenville Province.

The Paleo‐Tethys Suture Zone in the Afghan Hindu Kush‒Pamir: Geo‐Thermochronology, Geochemistry, Tectonics

Tectonics, Volume 45, Issue 3, March 2026.
Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

Age and structure of the Shyok Suture in the Ladakh region of Northwestern India: Implications for slip on the Karakoram Fault System [PDF]

, 2015
A precise age for the collision of the Kohistan-Ladakh block with Eurasia along the Shyok suture zone (SSZ) is one key to understanding the accretionary history of Tibet and the tectonics of Eurasia during the India-Eurasia collision.

Rapid Transition From High‐Pressure Metamorphism to Exhumation Driven by Orogen‐Parallel Extensional Shearing (Adula Unit, Eastern Central Alps)

Tectonics, Volume 45, Issue 2, February 2026.
Abstract In the Central Alps, the Adula unit exposes high‐ and ultra‐high‐pressure (HP‐UHP) metamorphic rocks, providing key insights into the subduction and exhumation dynamics of the former distal European margin. We investigate the San Bernardino Shear Zone (SBSZ), a top‐to‐the‐east extensional shear zone developed within orthogneiss and paragneiss ...

Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization

Journal of Metamorphic Geology, Volume 44, Issue 2, Page 158-175, February 2026.
ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

Thinning and Heating of Laramide Continental Lower Crust Recorded by Zircon Petrochronology

Geochemistry, Geophysics, Geosystems
Zircon grains from the metasedimentary lower crust of the Rio Grande Rift, New Mexico, preserve a metamorphic record of the transition from Laramide compression to Eocene extension.
