Trace fossils from the Baltoscandian erratic boulders in SW Poland

open access: yesAnnales Societatis Geologorum Poloniae, 2017
Many well preserved trace fossils were found in erratic boulders and the fossils preserved in them, occurring in the Pleistocene glacial deposits of the Fore-Sudetic Block (Mokrzeszow Quarry, Świebodzice outcrop). They include burrows ( Arachnostega gastrochaenae , Balanoglossites isp., ? Balanoglossites isp., ?

From Highlands to Henge: Refining the Provenance and Transport Pathways of Stonehenge's Altar Stone

open access: yesJournal of Quaternary Science, Volume 41, Issue 6, Page 888-895, August 2026.
ABSTRACT The Altar Stone, the 6000 kg central sandstone megalith at Stonehenge in southern England, is suggested to have originated from the Orcadian Basin in northeast Scotland, some 700 km away. However, its source location within this large basin remains unresolved and its mode of transport uncertain.

The Length of Martian Crater Rays and Their Relation to Lunar Cold Spots

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Impact‐generated crater rays are well‐documented on the Moon, with most appearing as high‐albedo streaks extending radially from a crater's center. On Mars, however, crater rays are significantly rarer and discernible only through thermal imaging due to their lower thermal inertia compared to surrounding terrain.

Subsurface Structure and Morphometry of the Wrinkle Ridges in the Late Amazonian Volcanic Unit on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Wrinkle ridges are widespread compressional tectonic features on Mars and are important records of the planet's global contractional history. However, their formation, evolution and subsequent modification by other geologic processes remain poorly constrained.

East Greenland Caledonides: stratigraphy, structure and geochronology: Lower Palaeozoic stratigraphy of the East Greenland Caledonides [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2004
The Lower Palaeozoic stratigraphy of the East Greenland Caledonides, from the fjord region of North-East Greenland northwards to Kronprins Christian Land, is reviewed and a number of new lithostratigraphical units are proposed. The Slottet Formation (new)

Evaluation of Submersible Pressure Transducers for Streamflow Monitoring in Small Streams

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 4, August 2026.
ABSTRACT Compact streamgages requiring minimal infrastructure and equipped with submersible pressure transducers (PTs) are increasingly used to monitor small streams, yet disparate implementations obscure their accuracy under real‐world conditions.

LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1847-1860, August 2026.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

The Last Glacial Maximum (LGM) glacier network of the Valsugana area (south-eastern European Alps and Prealps, NE Italy) [PDF]

open access: yesEiszeitalter und Gegenwart
We present new chronological and palaeoclimatological constraints on the evolution of the Valsugana glacier network (south-eastern European Alps) during the Last Glacial Maximum (LGM). The detection of ice-marginal sediments and landforms, related to the

A STEP IN STONE. ONTOLOGIES OF PODOMORPHIC PETROGLYPHS IN SOUTHERN SCANDINAVIAN BRONZE AGE

open access: yesOxford Journal of Archaeology, Volume 45, Issue 3, Page 330-348, August 2026.
Summary During the Bronze Age, a particular type of podomorphic petroglyph was produced on the outcrops by the sea in southern Scandinavia. In this text, their distribution, organization and articulation are analyzed in the Mälaren region of central‐eastern Sweden.

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

open access: yesJournal of Quaternary Science, Volume 41, Issue 5, Page 702-715, July 2026.
ABSTRACT The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...
