Study on Uranium Occurrence State of Sandstone-Type Uranium Deposits in Qianjiadian Region, Songliao Basin, China

IOP Conference Series: Earth and Environmental Science, 2020
Abstract The Qianjiadian uranium deposit is located in the southwest margin of Songliao basin. In this paper, electron probe, energy spectrum, back scattering analysis, scanning electron microscopy and other experimental methods are used to study uranium occurrence form and uranium mineral type in Qiandaidian uranium deposit. The results

Rethinking Collinearity in Self‐Organizing Maps: Evidence From Geophysical Data Classification

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract This study examines the impact of collinearity on unsupervised machine learning algorithms (UMLAs), specifically Self‐Organizing Maps (SOMs), for detecting lithological boundaries in geophysical data. Using a multi‐scale experimental framework that includes bivariate isotropic clusters, geologically complex Noddy simulations, and real‐world ...

Reservoir characterization and potential of the old red sandstone around the inner moray firth, NE Scotland [PDF]

, 1993
Old Red Sandstone deposition in North East Scotland occurred during Devonian times within the Orcadian Basin, a northeast-southwest elongated structure. The basin formed in an extensional tectonic regime that resulted from gravitational collapse of over ...

Subduction Initiation Volcanism Leading to Development of the Talkeetna Arc, Lower Shuyak Formation, Kodiak Archipelago, Alaska

Tectonics, Volume 45, Issue 4, April 2026.
Abstract Our understanding of subduction initiation remains limited by the difficulty of making direct observations of geologically recent examples. In the geologic record, supra‐subduction zone ophiolites are often interpreted to record syn‐initiation slab rollback and upper plate extension. Unfortunately, many ophiolites are decoupled from records of

Geochemistry of Mudstones/Silty Mudstones from the Qigequan Formation and Shizigou Formation in Yuejin-II Area, Southwestern Area of the Qaidam Basin: Implications for Sedimentary Environment and Sandstone-Type Uranium Mineralization

, 2022
The Qaidam Basin has been the focus of sandstone-type uranium prospecting since the 1950s. In recent years, relying on the uranium geological survey project supported by the China Geological Survey, and the cooperation with the Qinhai oil company ...

Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.
