Basin Research, Volume 38, Issue 3, May–June 2026.This study integrates post‐stack seismic attributes with a CNN‐based workflow to characterize sub‐seismic deformation in shale gas reservoirs. A near‐linear correlation is established between seismic characterization methods and borehole deformation counts.

Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA
Groundwater, Volume 64, Issue 3, Page 335-349, May/June 2026.Abstract Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to learn about the distribution and controls on deeper groundwater. In sedimentary basins across the United

Upper Ordovician formations in the Maysville area, Kentucky [PDF]
, 1966 Upper Ordovician strata in the Maysville area, Kentucky, are divided into five formations. The basal Kope Formation is overlain by the Fairview Formation. Above the Fairview are two newly defined map units, the Grant Lake Limestone and the overlying Bull Fork Formation. The Preachersville Member of the Drakes Formation overlies the Bull Fork.

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 311-336, May 2026.ABSTRACT This study investigates garnet–clinopyroxene double‐layered coronae in a metagabbronorite from the high‐grade metamorphic Gföhl Unit (Bohemian Massif). The coronae formed at the interfaces between relic magmatic orthopyroxene, still preserved in the cores of the coronae, and the plagioclase‐rich rock matrix.

First report of an aulaceratid stromatoporoid from the Ordovician of Baltica [PDF]
Estonian Journal of Earth SciencesThe aulaceratid stromatoporoids first appeared in the late Middle Ordovician and had achieved a worldwide distribution in tropical to subtropical shallow-marine environments by the Late Ordovician; however, their presence in Baltica has not been ...

Fascinating single‐cell red algae: models for evolution and adaptation
New Phytologist, Volume 250, Issue 3, Page 1424-1437, May 2026.Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

A reconnaissance geochemical drainage survey of the Criffel-Dalbeattie granodiorite complex and its environs [PDF]
, 1977 Regional geochemical reconnaissance by stream sediments and panned concentrates was undertaken over an area of 850 km 2 of south-west Scotland. Rocks of Ordovician to Permian age are exposed within the area but the major part is occupied by the ...
