Subduction Initiation and Early Subduction Zone Development: Insights From the P–T–t Path of the Bay of Islands Metamorphic Sole

Journal of Metamorphic Geology, Volume 44, Issue 7, Page 510-536, August 2026.
ABSTRACT The processes involved during subduction initiation (SI) remain poorly constrained, in part due to the rarity of geological archives. Ophiolites and their underlying metamorphic soles are thought to form during subduction zone infancy and may thus provide critical constraints. Metamorphic soles are derived from oceanic crust of the lower plate

PETROCHEMISTRY OF ROCKS IN THE PEGMATITE ZONE OF THE PRECAMBRIAN CENTRAL NIGERIA: AN ECONOMIC POTENTIAL PERSPECTIVE

Academy Journal of Science and Engineering, 2022
Pegmatites occur in association with amphibolites, minor granite-gneiss and quartzites in central Nigeria. Findings on their economic potentials are yet to reveal more representative and accurate depiction of their characteristics.

Thermodynamic Modeling of Lithium Enrichment During Partial Melting: The Importance of Partition Coefficients

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Predicting the partial melting conditions that generate Li‐rich peraluminous melts is of major economic and societal importance. However, existing models disagree on the optimal conditions (e.g., pressure, temperature, protolith) and, consequently, on targets for exploration.

P–T Modelling Constrains the Depth of Emplacement of the Porto Azzurro Pluton and Implies Minor Exhumation Caused by the Zuccale Fault (Island of Elba, Italy)

Journal of Metamorphic Geology, Volume 44, Issue 6, Page 440-469, July 2026.
ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with

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 ...

Multi‐Method Geochronology and P‒T Modeling Unravels the Thermo‐Tectonic History of the Rudall Province, Western Australia

Tectonics, Volume 45, Issue 2, February 2026.
Abstract The Rudall Province (RP) is a Paleo‐Mesoproterozoic belt that records numerous overprinting tectono‐metamorphic events. Situated on the eastern edge of the West Australian Craton (WAC), the RP represents a key area for understanding the Proterozoic assembly and subsequent tectonic history of Western Australia.
