A Millennium of Coastside Occupation. Micromorphological Insights From the Indigenous Site of Las Estacas Cave, Tenerife

Geoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT The archaeological site of Las Estacas Cave (NW Tenerife, Canary Islands) preserves some of the earliest human occupations in Tenerife, dating to the 2nd century CE, spanning the entire pre‐European time range up to the 15th century. Using soil micromorphology, this study applies a geoarchaeological approach to reconstruct site formation ...

Developing a Non‐Destructive Sourcing Method for Glassy Andesite and Basalt Artifacts

Geoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT Glassy andesite and basalt are volcanic rocks often valued as a lithic raw material by ancient people. Crucial to examining trade and migration routes of ancient communities is lithic sourcing based on geochemical comparisons of artifacts and known quarry outcrops.

Reconstructing the Holocene explosive eruptive history of the Erciyes volcano (Turkey) using proximal and distal tephra records

Journal of Quaternary Science, Volume 41, Issue 4, Page 645-659, May 2026.
ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...

Mid‐Infrared Compositional Spectral Parameters for the Lunar Thermal Mapper Instrument Onboard Lunar Trailblazer

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract The Lunar Trailblazer mission launched in February of 2025 with the goal of characterizing lunar surface water through a targeted campaign. One instrument on the mission, the Lunar Thermal Mapper (LTM), was tasked with measuring the surface temperature to compare with maps of the form and abundance of water on the lunar surface.

Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.

Identification of Obsidian Sources on Milos, Greece

Bulletin of the Geological Society of Greece, 2018
Obsidian, a natural volcanic glass, was used extensively in ancient times because of its quality as a raw material for sharp blades. As such, obsidian is of high interest for provenancing studies, since reliable provenancing can provide information about trade routes, extension of territory, long-distance contacts and the mobility of prehistoric ...
