The Origin of Carbonate Magmas Predating and Accompanying Main‐Phase LIPs Eruptions

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Some large igneous provinces (LIPs) are associated with precursory carbonatite eruptions. Models for precursory carbonatites invoking partial melting of a carbonate metasomatized lithosphere appear implausible, given the long time needed for heat conduction from the plume head.

Lithospheric boundaries on the eastern Siberian platform

open access: yesASEG Extended Abstracts, 2001
The regional mapping of large lithospheric blocks can provide guidance for mineral exploration, because such large-scale structures, and particularly the boundaries between them, may control the emplacement of several types of large ore bodies. This study uses a combined analysis of potential-field geophysical data and mantle petrology, to map major ...

Enhanced Solar Radiation Attenuation in the Arctic Shelf Driven by Warming‐Induced Terrestrial Inputs

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Arctic warming accelerates permafrost thaw and coastal erosion, increasing terrestrial material transport to the ocean. Using Moderate Resolution Imaging Spectroradiometer (MODIS) data (2002–2023), we report a widespread increase in the diffuse attenuation coefficient Kd(490) across Arctic shelves since 2018, notably in the Laptev and Kara ...

THERMAL HISTORY OF THE GULI PLUTON (NORTH OF THE SIBERIAN PLATFORM) ACCORDING TO APATITE FISSION-TRACK DATING AND COMPUTER MODELING

open access: yesГеодинамика и тектонофизика, 2020
We present the first results of fission-track dating of apatite monofractions from two rock samples taken from the Southern carbonatite massif of the world’s largest alkaline ultrabasic Guli pluton (~250 Ma), located within the Maymecha-Kotuy region of ...

Microfluidic Engineering of Chitosan‐Coated Nanoemulsions for Controlled Release and Stability in Space Pharmaceutics

open access: yesAdvanced Materials Technologies, Volume 11, Issue 12, 18 June 2026.
Microfluidic engineering enables the fabrication of chitosan‐coated, melatonin‐loaded nanoemulsions with controlled release and enhanced physicochemical stability for space pharmaceutics. Interfacial biopolymer coating modulates droplet behavior under accelerated thermal stress and simulated microgravity.
