Constraints on Magma Pressure Distribution During Long Range Lateral Propagation of Giant Radial Dyke Swarms

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Giant dyke swarms are important but enigmatic components of magma transport in the Earth and terrestrial planets. Although widely documented on Earth, Venus, and Mars as extending laterally for 100–1,000 s of kilometers from their magma sources, the reasons for this extraordinary lateral propagation are not known.

Underground mining impact on groundwater in Kuye River Basin, China: A coupling model study

open access: yesRiver, Volume 4, Issue 1, Page 106-115, February 2025.
The Kuye River Basin has experienced a rapid depletion of groundwater due to the increased coal production. In this study, by introducing the empirical equations derived from the three zone theory in the coal mining industry in China as a boundary condition, a calculation model was developed by coupling the soil and water assessment tool and visual ...

Towards a new generation of fluvial facies models for the interpretation of ancient deposits, based on inter‐annual peak discharge variance of modern rivers

open access: yesSedimentology, Volume 72, Issue 1, Page 275-329, January 2025.
ABSTRACT Fluvial facies models based on river planform are flawed and not fully fit for purpose. An alternative approach to classifying fluvial deposits is based on river discharge characteristics. A recent paper showed that the co‐efficient of variance of annual peak discharge (CVQp) correlates well with the characteristics of preserved alluvium for a

Geochemical Constraints on the Generation of Coalbed Methane in the Weizhou Area, South‐Central Ningxia, NW China: Insights From Stable Isotopes and Organic Petrology

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
Amid growing global clean energy demand, coalbed methane (CBM) in the coal‐rich Weizhou area holds great development value. This study explores Weizhou CBM′s geochemical traits and genesis via analyzing gas compositions (Shanxi and Taiyuan Formations), stable isotopic distributions (δ13C1, δD, δ13CO2, and δ15N), and their burial depth variations ...
