Impact Crater Hydrothermal Systems Support Rapid Microbial Enrichment and Diverse Metabolic Potential

open access: yesGeobiology, Volume 24, Issue 6, November/December 2026.
ABSTRACT Impact crater hydrothermal systems, formed after asteroid and comet impacts, have been proposed as promising habitats for life on early Earth and as key targets in the search for life on planetary bodies such as Mars, since they provide liquid water and active geochemical turnover.

U-Pb Dating of Silicic Volcanic Rocks of the Eastern Coromandel Peninsula [PDF]

open access: yes, 2012
The eastern Coromandel Volcanic Zone (CVZ) is an area of predominantly andesite-dacite-rhyolite volcanism which was erupted and subsequently hydrothermally altered in parts during the Late Miocene to Early Pleistocene.

Refractory Metakaolin Geopolymers: Achieving High Mechanical Strength and Near‐Zero Shrinkage After Exposure to 800°C

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 11, November 2026.
ABSTRACT Metakaolin‐based geopolymers are candidate binders for refractory and fire‐resistant components because they combine ceramic‐like thermal stability with low‐temperature processing. Their use is still restricted by a trade‐off: Formulations that develop high strength shrink substantially near 800°C, while formulations that remain dimensionally ...

U-Pb age and Hf-Nd-Sr-Cu-S isotope systematics of the Binyuda and Dyumtaley ore-bearing intrusions (Taimyr, Russia)

open access: yesЛитосфера, 2016
We present for the first time U-Pb age data and Hf-Nd-Sr-Cu-S isotope signatures for lithologies and associated sulphide ores from the Binyuda and Dyumtaley ultramafic-mafic intrusions located in the limits of the Taimyr Peninsula (Russian Arctic ...

6‐Month Clinical Evaluation of Reduced Dentin Etching Time Using Universal Adhesives in Noncarious Cervical Lesions: A Double‐Blind Randomized Clinical Trial

open access: yesJournal of Esthetic and Restorative Dentistry, Volume 38, Issue 11, Page 2163-2176, November 2026.
ABSTRACT Objectives To evaluate the effect of reduced dentin etching time on the clinical performance of two universal adhesive systems in noncarious cervical lesions (NCCLs). Methods A total of 144 NCCLs restorations were randomly placed in 36 participants according to four experimental groups: SUP5 (Scotchbond Universal Plus adhesive [pH ≈2.5–2.7 ...

Position of the Lhasa Terrane and Two‐Stage Crustal Shortening During the India–Asia Collision

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The paleolatitudinal change of the Lhasa Terrane is critical for estimating the timing of the India–Asia collision and associated syn‐to post‐collisional crustal shortening, but its paleoposition is highly debated. Here we present integrated geochronologic and paleomagnetic results from the Lower Eocene Nianbo Formation in the Linzhou Basin ...

Onset of Thrusting at ca. 23 Ma in East Kunlun Mountains, Northern Tibet, Recorded by Syntectonic Strata

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The timing of Cenozoic deformation in the East Kunlun Mountains, northern Tibet, is crucial for understanding plateau growth but remains disputed due to the scarcity of direct chronological constraints on specific tectonic structures. Here, we present a high‐density‐sampling magnetostratigraphic record from the Xiaohongshan section, interior ...

Red Coloring of Glaze by Manganese-Zircon Purple Pigment [PDF]

open access: yes
Red coloring of glaze by mixing three kinds of zircon-based pigments was studied. The zircon-based pigments used in the glaze have chemical and thermal stabilities in comparison with other ceramic pigments.
