A Physically Based Storage‐Runoff Relationship for Steep Hillslopes and Its Application to Distributed Flood Modeling

open access: yesWater Resources Research, Volume 62, Issue 11, November 2026.
Abstract Kinematic wave models are widely used to represent hillslope runoff in distributed hydrological models. However, their simplified descriptions often prevent the effective use of observed soil hydraulic parameters during calibration. To address this limitation, we derived a new analytical storage–runoff relationship that explicitly incorporates

Onset of Thrusting at ca. 23 Ma in East Kunlun Mountains, Northern Tibet, Recorded by Syntectonic Strata

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The timing of Cenozoic deformation in the East Kunlun Mountains, northern Tibet, is crucial for understanding plateau growth but remains disputed due to the scarcity of direct chronological constraints on specific tectonic structures. Here, we present a high‐density‐sampling magnetostratigraphic record from the Xiaohongshan section, interior ...

The Magnetic Signature of Shear Zones in Marbles and Experimental Simulations

open access: yesGeoscience Data Journal, Volume 13, Issue 4, October 2026.
This dataset explores how strain, microstructure, texture and magnetic susceptibility interact in natural and experimental shear zones. It includes data from low‐ and high‐temperature marble shear zones and analogue experiments simulating different deformation regimes.

Diagnosis of the Transition from Rock to Soil in a Granodiorite

open access: yesJournal of Geotechnical and Geoenvironmental Engineering, 2004
This paper describes an attempt to develop a method to define when granodiorite loses its properties as a rock and transforms into soil material. The research program approached the problem from a mechanistic point of view by comparing the pore water pressures generated during isotropic compression with the apparent—and micro—porosities, in terms of a ...

Petrology of the Kesengawa Granodiorite, Kitakami Mountains, Northeast Japan [PDF]

open access: yes, 1978
The Kesengawa granodiorite mass, a representative Cretaceous granitoid intrusive of the Kitakami mountain region, is divided into a basic and an acidic rock group.

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 4, Page 725-752, October/December 2026.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Pre‐Eruptive Volatiles and Magma Storage Depth for the 2018 Eruption at Mount Veniaminof, Alaska

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Mount Veniaminof is a frequently active, open‐system arc volcano on the Alaska Peninsula, part of the Alaska‐Aleutian arc. Mount Veniaminof's September–December 2018 eruption began with small lava flows and culminated in a larger explosive event in November that produced a 450 km long continuous ash plume—one of the volcano's most significant ...

Geochronology and Petrogenesis of Ahetala Granodiorite in South Tianshan Orogenic Belt, Xinjiang: New Constraints on the Tectonic Evolution of the South Tianshan Ocean

open access: yes, 2022
The Ahetala granodiorite is located in the western section of the South Tianshan Orogenic Belt (STOB), which is of great significance regarding the dispute on the closing date of the South Tianshan Ocean (STO) and the tectonic evolution of STOB.
