Heterostructure‐Engineered Conductive MOFs Coupled with MoSe2@MXene Framework for Efficient and Selective Lithium Extraction from Salt Lake Brine via Capacitive Deionization

Advanced Science, Volume 13, Issue 17, 23 March 2026.
This schematic illustrates a capacitive deionization (CDI) system for the selective extraction of lithium from salt‐lake brine. The system employs a cathode fabricated from the Fe‐THBQ@MoSe2@MXene composite alongside an activated carbon (AC) anode. Upon applied voltage, the cathode demonstrates high efficiency in capturing Li+ ions while effectively ...

Exploration and Petrogenesis of Corundum-Bearing Pegmatites: A Case Study in Migif-Hafafit Area, Egypt

Frontiers in Earth Science, 2022
A net of pegmatite veins crosscut gneiss and dismembered ophiolitic ultramafic rocks are abundant in the Migif-Hafafit culmination area, South Eastern Desert, Egypt. Some of these pegmatites are corundum-bearing.

Growth and Chemical Evolution of the Kohistan Arc Crust, Northern Pakistan, Western Himalayas

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil arcs which expose the middle‐lower crust have the potential to shed light on active arc processes because magmatic rocks from the entire history of the arc can be examined. We present new geochemical data from the middle crust of the Kohistan Arc and use existing geochemical and geochronological literature data from this arc to ...

The effect of F on the density of haplogranite melt [PDF]

, 1993
The densities and thermal expansivities of F-bearing haplogranitic glasses and liquids have been investigated using a combination of scanning calorimetry and dilatometry. F2O-1 reduces the density of haplogranitic liquids (at 750 °C) from 2.295 + 0.006 g/

The Paleo‐Tethys Suture Zone in the Afghan Hindu Kush‒Pamir: Geo‐Thermochronology, Geochemistry, Tectonics

Tectonics, Volume 45, Issue 3, March 2026.
Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

Newly Discovered Triassic Lithium Deposits in the Dahongliutan Area, NorthWest China: A Case Study for the Detection of Lithium-Bearing Pegmatite Deposits in Rugged Terrains Using Remote-Sensing Data and Images

Frontiers in Earth Science, 2020
Rare metals, such as lithium and cobalt used in rechargeable batteries, have increased in value as demands for them escalates. Concentrations of lithium-bearing minerals are found in closed-basin brines, granitic pegmatites, and associated granitic rocks

On the identification of Ti-Ta-Nb-oxides in “wiikites” from Karelia [PDF]

, 2018
Purpose. With respect to the nature of Ti-Ta-Nb-oxides, which are included in the mineral associations that have historically gone by the now outdated name of “wiikites”, there is no unanimity of opinion.

Multi‐Method Geochronology and P‒T Modeling Unravels the Thermo‐Tectonic History of the Rudall Province, Western Australia

Tectonics, Volume 45, Issue 2, February 2026.
Abstract The Rudall Province (RP) is a Paleo‐Mesoproterozoic belt that records numerous overprinting tectono‐metamorphic events. Situated on the eastern edge of the West Australian Craton (WAC), the RP represents a key area for understanding the Proterozoic assembly and subsequent tectonic history of Western Australia.
