Borehole Logging Lithological Classification in Carbonatite‐Hosted Niobium Deposit Integrating Geophysical and Geochemical Data With Self‐Organizing Maps

open access: yesGeophysical Prospecting, Volume 74, Issue 3, March 2026.
ABSTRACT Lithological classification from borehole data remains challenging in geologically complex alkaline–carbonatite systems, where compositional overlap and gradual transitions between lithotypes limit conventional interpretation methods. This study presents an integrated and automated workflow for drill‐core lithological classification using self‐

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

Depositional Interplay Between the Ancestral Rocky Mountains and Ouachita–Marathon–Sonora Orogenies: Insights From Provenance Records in the Late Palaeozoic Marfa Basin, West Texas, USA

open access: yesBasin Research, Volume 38, Issue 2, March/April 2026.
Provenance records from the late Palaeozoic Marfa Basin in West Texas reveal the transition from the Ancestral Rocky Mountains to the Ouachita–Marathon–Sonora orogenies during the early Permian in SW Laurentia. ABSTRACT The Marfa Basin in West Texas is a late Palaeozoic synorogenic depocenter associated with regional deformation linked to the Ancestral

Quantifying Multi‐Source Sediment Supply in a Tropical Foreland Basin (Oligocene‐Miocene Nyalau Formation, Borneo)

open access: yesBasin Research, Volume 38, Issue 2, March/April 2026.
Detrital zircon unmixing identifies three sediment sources for the Oligocene–Miocene Nyalau Formation, including a previously unrecognised syn‐depositional component characterised by Oligocene–Miocene volcanic zircons and Neoproterozoic populations absent from established sources.
