Time Variance in Snowmelt Partitioning: A Mechanistic Modeling Approach to Explore the Role of Catchment Structure and Pre‐Snow Rainfall

open access: yesWater Resources Research, Volume 62, Issue 1, January 2026.
Abstract Understanding how snowmelt is partitioned into different hydrologic flowpaths/storages—and how this partitioning varies over time—is essential for predicting water availability and quality under climate variability. In this study, we examine the time‐variance of snowmelt partitioning patterns (SPP) in response to interannual variations in ...

MULTIDISCIPLINARY APPROACH TO STUDY MIGMATITES: ORIGIN AND TECTONIC HISTORY OF THE NASON RIDGE MIGMATITIC GNEISS, WENATCHEE BLOCK, CASCADES CRYSTALLINE CORE, WA, USA

open access: yesEarth Sciences Research Journal, 2008
The Nason Ridge Migmatitic Gneiss of the Cascades Core is a migmatitic unit comprising concordant pelitic schist and gneiss, amphibolite, and tonalite gneiss, and cross cutting tonalite, quartz-rich granitoid, and pegmatite. There are several generations

The Neoproterozoic Throssell Range Group, Western Australia: A Peri‐Marginal Continental Basin in Rodinia and Its Implications for the Centralian Superbasin

open access: yesBasin Research, Volume 38, Issue 1, January–February 2026.
This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

Ultrahigh‐Temperature Metamorphism and Near‐Isobaric Cooling of Garnet‐Orthopyroxene Granulite Xenoliths in the Sancheong Anorthosite, Yeongnam Massif, Korea

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 1, Page 20-46, January 2026.
ABSTRACT Elevated heat flow associated with mafic magmatism in accretionary orogens has often been proposed as a driving mechanism for (ultra)high‐temperature (UHT) metamorphism and anatexis. The Sancheong–Hadong complex, located in the southern Yeongnam Massif, Korea, consists of a ca.

Sm-Nd isotopic systematics of the ancient Gneiss complex, southern Africa [PDF]

open access: yes
In order to shed some new light on the question of the absolute and relative ages of the Ancient Gneiss Complex and Onverwacht Group, a Sm-Nd whole-rock and mineral isochron study of the AGC was begun.

Characterisation of Underground Organs as a Basis for Estimating Rhizome Resprouting Potential: The Case Study of Two Invasive Reynoutria Taxa (Polygonaceae)

open access: yesWeed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT The Japanese knotweeds (Reynoutria japonica complex; Polygonaceae) are characterised by a highly efficient vegetative propagation. Their resprouting capacity is associated with rhizomes, whose nodal structure distinguishes them from non‐regenerative roots.

Speculations on nature and extent of Archean basement in Labrador as indicated by SR, ND and PB isotopic systematics of proterozoic intrusives [PDF]

open access: yes
The Sm-Nd and Rb-Sr isotopic compositions of mid to late Proterozoic (approximately 1.6 to 1.1 Ga) massif-type anorthosites and mafic intrusives in the eastern Canadian shield are correlated with geographic location.
