Neoproterozoic magmatic evolution of the southern Ouaddaï Massif (Chad)
This paper presents new petrological, geochemical, isotopic (Nd) and geochronological data on magmatic rocks from the poorly known southern Ouaddaï massif, located at the southern edge of the so-called Saharan metacraton. This area is made of greenschist

Bismuth‐Based Photocatalysts for Water Remediation: Design Strategies, Mechanisms, and Challenges
This review highlights representative design strategies for bismuth‐based semiconductor photocatalysts in solar‐driven water purification. Emphasis is placed on electronic structure regulation, oxygen‐vacancy engineering, and interfacial coupling to enable efficient full‐spectrum light utilization, improved charge separation, and selective oxidation in

Is there a Grenvillian basement in the Guerrero-Morelos Platform of Mexico?
In the Guerrero-Morelos platform (Guerrero State, Mexico) the adakitic rocks of Early Tertiary age contain abundant hornblende-rich tonalite xenoliths. Zircon crystals have been concentrated from both adakites and xenoliths, and dated using in-situ U-Pb ...

Magmatism has profoundly influenced the evolution of the geosphere, hydrosphere, atmosphere, and biosphere in back-arc basins. However, the timing of the magmatism in the Okinawa Trough (OT) is not well constrained by the age spectra of zircons.
