Coupled authigenic Mg silicate and carbonate precipitation in saline lakes of the Salar de Atacama, Northern Chile

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Sediments, unlithified and lithified microbial mats in the Salar de Atacama, are formed by similar pathways involving coupled precipitation of authigenic Mg silicate and calcium carbonate. Differences in products reflect differences in the initial distribution of organic biomass.

Soil Organic Matter Stabilization by Polyvalent Cations in a Buried Alkaline Soil

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Buried paleosols can store large quantities of organic carbon (C), much of which persists for millennia due to isolation from surface processes that promote decomposition. Subsoil organic matter (SOM) persistence is often enhanced by mineral associations and ionic conditions—particularly high clay content and polyvalent cations—that limit ...

Semidiaphanam Tremuli Narcissuli Ideam Lacteam1: Ehrenfried Walther von Tschirnhaus (1651–1708) and His Determined Search for the Porcelain Principle

open access: yesArchaeometry, Volume 68, Issue 1, Page 120-131, February 2026.
ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...
