Indicio de vermiculita en el skarn magnésico (aposkarn flogopitico de la garrechosa (Santa Olalla; Huelva)

, 1981
Los skarns magnésicos de "La Garrenchosa" muestran tres etapas en su evolución. Primero, una etapa de alta temperatura con desarrollo tanto de exoskarns de tipo "frente" entre el magma y la roca de caja dolomítica así como de tipo bimetasomático entre el

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

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...

Skarns and Skarn Deposits

, 1992
Skarn deposits occur throughout the world and have been mined for a variety of elements. This paper describes the basic stages of skarn formation and the main causes of variation from the general evolutionary model. Seven major classes of skarn deposits (

KNaCaSi4O10 Obtained From Crystallization Experiments in the Quaternary System K2O–Na2O–CaO–SiO2

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
The compound KNaCaSi4O10 has been identified in crystallization experiments of glasses in the quaternary system K2O–Na2O–CaO–SiO2 and has undergone structural characterization. Vibrational spectroscopic data have been acquired and interpreted using density functional theory (DFT) calculations.

Quantifying Vein Network Permeability in Dehydrated Serpentinites Using Thermodynamics and Generative AI

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Fluids released from subducting hydrated rocks influence volcanism, tectonics, and geochemical cycling, but the mechanisms of fluid escape in subduction zones remain poorly understood. We address this issue by investigating the Erro‐Tobbio meta‐serpentinites (ET‐MS), Italy, exhumed serpentinite rocks that preserve extensive dehydration vein ...

Rare Earth Elements in Plants of the Peak Range Volcanics (Queensland), Australia Exploration Target: A Biogeochemical Prospecting Tool

Ecological Research, Volume 41, Issue 1, January 2026.
The Peak Range Volcanics in central Queensland, Australia is naturally enriched with REEs (Rare Earth Elements). Fieldwork was conducted to analyse REEs in plant species occurring in this area. ABSTRACT Rare Earth Elements (REEs) are critical for high‐tech technologies in the green energy transition.

Two stages of skarn formation in the Hämmerlein tin-skarn deposit, western Erzgebirge, Germany

, 2017
The Hämmerlein Sn-skarn deposit of the western Erzgebirge is hosted in early Palaeozoic schists and gneisses and is closely associated with one of the most voluminous granite intrusions of the Erzgebirge, the Eibenstock granite.
