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 ...

Drainage Divide Migration in Response to Asymmetric Uplift at Eastern Qinling, China

Terra Nova, EarlyView.
ABSTRACT Drainage divide migration shapes landscape, sediment patterns, and biodiversity, which is affected by a variety of factors. While geomorphic index and numerical simulations have been employed to investigate divide migration, previous studies ignore the present‐day vertical velocity field.

Intermittent Brittle and Ductile Deformation as Recorded by Dating of Ultramylonites and Pseudotachylytes in Extending Continental Crust (Ivrea‐Verbano Zone, Italy)

Terra Nova, EarlyView.
ABSTRACT Mylonites and pseudotachylytes play a crucial role in defining the rheology of extending continental crust. In this context, determining the age of brittle‐ductile deformation is fundamental to understanding the rifting evolution stages. Here, we investigate the Premosello Shear Zone, an extensional structure of the Ivrea‐Verbano lower crust ...

Magnetostratigraphy and Source Characterisation Across the Early Miocene Unconformity, Northern Rocky Mountains, USA

Terra Nova, EarlyView.
ABSTRACT The early Miocene unconformity (EMU) formed during a transition in the tectonic regime of western North America that coincided with faunal diversification. The Railroad Canyon section in the northern Rocky Mountains provides a complete geologic record around this event. Our new magnetostratigraphic study in combination with published U‐Pb ages
