Treasures of the Serra da Jiboia (Bahia, Brazil): a new species of Racinaea and an overview of the local Bromeliaceae flora

Nordic Journal of Botany, Volume 2026, Issue 10, October 2026.
Serra da Jiboia, located in the south‐central region of Bahia, represents an important ecotone between the Atlantic Forest and the Caatinga and harbors high floristic diversity and numerous endemic species. The Bromeliaceae family, well represented in the region, stands out for its ecological importance and adaptability to various microenvironments ...

Thermochemical Structure of the Superior Craton and Environs: Implications for the Evolution and Preservation of Cratonic Lithosphere

Geochemistry, Geophysics, Geosystems
The Archean Superior craton was formed by the assemblage of continental and oceanic terranes at ∼2.6 Ga. The craton is surrounded by multiple Proterozoic mobile belts, including the Paleoproterozoic Trans‐Hudson Orogen which brought together the Superior

Geochemical criteria for identifying diamond-bearing areas [PDF]

E3S Web of Conferences
The paper demonstrates that diamondiferous objects may be pinpointed even by the middle-scale geochemical surveys. Relevant criteria were developed to identify and classify such objects by their prospectivity.

Sensitization of OSL Signals in Quartz and Provenance Implications: Insights From Multi‐Spectroscopic Analysis of Quartz From Multiple Geological Settings

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Quartz optically stimulated luminescence (OSL) sensitivity and electron spin resonance (ESR) signals have been empirically proposed as indicators of sediment provenance. OSL sensitivity is defined as luminescence produced per unit dose (Gray: Gy) per unit mass (mg).

Gold metallogeny associated with craton destruction: A geophysical perspective from the North China Craton

Ore Geology Reviews, 2016
Abstract Currently ranking as the largest producer of gold in the world, China's gold reserves are spread over 200 major gold deposits and several minor deposits. A large part of these belong to the late Mesozoic gold deposits in the North China Craton (NCC) that occur along craton margins, as well as within the cratonic interior in reactivated paleo

Late Mesozoic Intracontinental Deformation in the Northern Margin of the North China Craton: A Case Study From the Shangyi Basin, Northwestern Hebei Province, China

Frontiers in Earth Science, 2021
During the late Mesozoic, the East Asian continent underwent a complex tectonic history due to multiple episodes of plate convergence. How the crust responds to the multiple plate convergence in the North China Craton (NCC) remains unclear.

The Dense MORB Fraction Controls the Dynamic Stability and Hydration Potential of the Mantle Transition Zone

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The mantle transition zone (MTZ; ∼410–660 km depth) is a major reservoir of water and mid‐ocean ridge basalt (MORB)‐like materials, yet how composition and hydration regulate its physical stability remains unclear. Using geodynamical modeling, we examine the joint effect of water content and dense MORB fraction on the density, viscosity, and ...

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...
