The Earth's Greatest Porous Media
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

Gamma Rays Signal the Vulnerability of Forest to Extreme Drought
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Extreme drought and heat are driving forest die‐off globally, yet regional‐scale mapping of subsurface water storage capacity, governing forest vulnerability, remains a major challenge. Here, we demonstrate that airborne gamma‐ray spectrometry (GRS) of potassium (40K) decay provides a powerful proxy for subsurface constraints on water ...

An occurrence of Lower Palaeozoic rocks within the Precambrian terrain near Sukkertoppen
Rapport Grønlands Geologiske Undersøgelse, 1966 An occurrence of Lower Palaeozoic rocks within the Precambrian terrain near Sukkertoppen, West Greenland, was discovered in 1965 by Caj Kortman and Jens Gothenborg working under fil. mag. L. Keto for Kryolitselskabet Øresund AIS, Copenhagen. The material was kindly placed at the disposal of the writer for further study.

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China
Geological Journal, Volume 61, Issue 8, Page 2258-2278, August 2026.Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1463-1480, August 2026.Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.
