Abstract The closure of the Paleo‐Tethys Ocean was one of the most important global geological events which formed the framework of the East Asian continent during the early Mesozoic. The Longmu Co‐Shuanghu suture zone is considered to record closure of the main basin of the Paleo‐Tethys Ocean.

Abstract Marine carbonate carbon isotopes (δ13C), over orbital to multi‐million‐year timescales, provide critical insight into the carbon cycle connecting Earth's atmosphere, lithosphere, hydrosphere and biosphere. However, the influence of astronomical forcing on deep time carbon cycle dynamics remains poorly constrained.

Abstract The Cretaceous–Eocene island arc of Hispaniola is currently shortened between the Bahamas carbonate platform to the north and the thickened crust of the Caribbean Large Igneous Province (CLIP) to the south. Within this transpressional setting, the 15–22‐km‐thick, ∼100‐km‐wide Beata Ridge (BR), the thickest portion of the CLIP, acts as a ...

Abstract This study highlights the need to re‐evaluate energy transfer in the upper thermosphere at high latitudes through analysis of 9‐year measurements of neutral wind (u) from a Fabry‐Perot interferometer and ion velocity (v) from a Dynasonde in Tromsø, Norway.

Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.
