Biogeochemical characterization of micritized carbonate grains in the shallow‐marine Al‐Kharrar Lagoon (Red Sea, Saudi Arabia)

Sedimentology, EarlyView.
ABSTRACT Micritization of marine carbonate grains is an early diagenetic process involving the alteration of the original carbonate fabric and the formation of cryptocrystalline textures through cycles of dissolution and reprecipitation. Microorganisms play a significant role in this process, actively contributing to the formation of constructive and ...

The Chamrousse Ophiolite (Western Alps, France): Relict of a Devono‐Carboniferous Ocean

Terra Nova, EarlyView.
ABSTRACT The Chamrousse ophiolite (Western Alps, France) is one of the best‐preserved Variscan relicts of Cambro‐Ordovician oceanisation within the northern Gondwana margin. This study presents new in situ U–Pb isotope analyses on zircon grains from that ophiolite, revealing that the oceanic stage in Chamrousse has occurred 150 Ma later than estimated.

Schist Belts of the Benin‐Nigeria Shield Reveal a Neoproterozoic History

Terra Nova, EarlyView.
ABSTRACT Belts of metasedimentary rocks (schist belts) in the Benin‐Nigeria Shield (BNS) are investigated for the first time using U–Pb dating and Lu‐Hf isotope analysis of detrital zircons. We report maximum depositional ages that place their deposition firmly in the Neoproterozoic and link them with strata in the Dahomey Belt, the central African ...
