Linking palaeo‐wildfire to depositional environmental and ecological dynamics of an Early–Middle Pennsylvanian fluvial‐tidal transition zone—Palynology and pyrolysis evidence

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

Trace element geochemistry of peridotites from the Izu-Bonin-Mariana Forearc, Leg 125

open access: yes, 1992
Trace element analyses (first-series transition elements, Ti, Rb, Sr, Zr, Y, Nb, and REE) were carried out on whole rocks and minerals from 10 peridotite samples from both Conical Seamount in the Mariana forearc and Torishima Forearc Seamount in the Izu ...

Numerical solution of degenerate stochastic Kawarada equations via a semi-discretized approach

open access: yes, 2018
The numerical solution of a highly nonlinear two-dimensional degenerate stochastic Kawarada equation is investigated. A semi-discretized approximation in space is comprised on arbitrary nonuniform grids.

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an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents.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 ...
