Implicit Neural Representation to Improve the Resolution of 3D Electrical Resistivity

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Electrical resistivity tomography (ERT) is a subsurface imaging geophysical technique. Traditional ERT inversion methods, such as smoothness‐constrained least‐squares approaches, often suffer from discretization artifacts when reconstructing electrical resistivity from resistance measurements.

OSL Characteristics of Sandstone-type Uranium Deposits Soil and Optimization of Measurement Process

Yuanzineng kexue jishu
Sandstone-type uranium deposits are recognized as the main type for uranium exploration and mining in China, owing to their large reserves and ease of extraction. However, some of the sandstone-type uranium deposits are covered by thick overburden layers

REE/trace element characteristics of sandstone-type uranium deposits in the Ordos Basin [PDF]

Chinese Journal of Geochemistry, 2006
The major elements, trace elements and REEs were analyzed on the samples collected from the sandstone-type uranium deposits in the Ordos Basin to constrain the mechanism of uranium enrichment. The total REE amount ranges from 36.7 to 701.8 μg/g and the REE distribution patterns of the sandstone-type uranium samples are characterized by LREE enrichment ...

Exhumation History of the Sangre de Cristo Range, Colorado, From Mid‐ to Low‐Temperature Thermochronology: New Insights Into Laramide Contraction and Oligocene–Miocene Extension in the Northern Rio Grande Rift, USA

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Sangre de Cristo Range in southern Colorado records a complex tectonic history that includes Late Cretaceous–Eocene Laramide contraction and Oligocene–Quaternary Rio Grande rift extension. We present new thermochronologic data (40Ar/39Ar, fission‐track, (U‐Th)/He) and thermal history models that provide insight into this polyphase history ...

Ore Zoning, Geochemistry and Genesis of Iron Mineralization in Hormuz Volcano-Sedimentary Sequence, Larak Island, South of Bandar Abbas

Journal of Economic Geology, 2023
Iron mineralization has occurred in Larak Island, located 30 km south of Bandar Abbas, within the Persian Gulf, in the Zagros structural zone. Stratigraphically, Larak Island dominantly consists of the Late Proterozoic Hormuz volcanic-sedimentary series,

Thermal and Structural Reconstruction of an Eroded Foreland Basin: Central Appalachian Basin, USA

Basin Research, Volume 38, Issue 4, July–August 2026.
New low‐temperature thermochronology and modelling reveal a complex thermal history for the central Appalachian Basin. Results indicate Carboniferous exhumation of the fold‐thrust belt and Mesozoic heating in the foredeep linked to the Rome Trough. Deeply buried Devonian source rocks were consequently pushed past the peak oil and gas windows.

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

Journal of Quaternary Science, Volume 41, Issue 5, Page 770-783, July 2026.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.
