Post-Acadian metamorphism in the Appalachians

open access: yes, 1988
Well-documented post-Acadian metamorphism occurs at three locales along the eastern flank of the Appalachians, where it has affected Avalonian basement and/or Carboniferous cover.

Metasomatites of medium and mafic composition from Nyaschevo massif (Ilmeny Mauntains, South Urals)

open access: yesЛитосфера, 2015
The results of the study of mediosiliceous and mafic metasomatites located in ultramafic and mafic rocks Nyaschevo massif presents in the paper. The texthural and structural features of these rocks allow to attribute them to tectonites - protomylonites and

Cretaceous–Palaeogene Plate Boundary Evolution at the Pacific Margins of Zealandia and West Antarctica

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Improved satellite‐derived gravity data support updated interpretations and models of ancient plate boundaries and plate motions affecting Zealandia and West Antarctica. The models combine to confidently resolve hundreds of kilometres of Late Cretaceous–Eocene motion between the Pacific and Lord Howe plates, confirming that plate circuit constructions ...

MetaMorphe [PDF]

open access: yes, 2015
The creative promise of 3D digital fabrication tools is tremendous. However due to the wide range of tools and interfaces, a common static file format called STL is used for sharing designs. While customization tools add creative handles to these digital models, they are often constrained to pre-configured parameters limiting the creative potential of ...

The Earth's Greatest Porous Media

open access: yesPerspectives 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?

Impact of Wildfire‐Emitted Black Carbon on Snowmelt Across Western North America

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Wildfires are a major source of black carbon (BC) and their increasing frequency and intensity have enhanced BC deposition onto snowpack across western North America, which accelerates snowmelt and triggers multiple feedbacks that can substantially alter atmospheric composition and regional hydrology. Using the Weather Research and Forecasting

Carryover effects in amphibians: Approaches, drivers, metrics, and detection

open access: yesEcological Monographs, Volume 96, Issue 4, November 2026.
Abstract Carryover effects—where early‐life experiences influence performance at later stages—have become an important concept in ecological research. These effects can occur across life history stages and are particularly intriguing in organisms with complex life cycles, especially when different stages occupy distinct ecological niches.
