Scientific ReportsSulfur (S), an essential volatile in subduction zone magmatism, exhibits higher solubility in aqueous fluids compared to silicate melts. Despite its importance, the partitioning of S between aqueous fluids and silicate melts under the conditions of ...

Coral Paleoclimate Perspectives Support the Role of Low‐Latitude Forcing on the 4.2 ka BP Event
Geophysical Research Letters, 2023 The 4.2 ka BP Event is an abrupt climate change that might have contributed to the collapse of ancient civilizations and marks the transition between the mid‐ and late‐Holocene.

The Depositional Record, EarlyView.Emblematic of global coral‐reef ecosystem decline, the coral ecosystem‐engineer Acropora palmata is now rare throughout much of the western Atlantic. We report for the first time, a significant record of late‐Holocene A. palmata populations that existed from ~4500 to 375 years before present in the Dry Tortugas, FL, USA.

Geochemistry of silicate-rich rocks can curtail spreading of carbon dioxide in subsurface aquifers [PDF]
Nat. Commun. 5:5743 (2014), 2014 Pools of carbon dioxide are found in natural geological accumulations and in engineered storage in saline aquifers. It has been thought that once this CO2 dissolves in the formation water, making it denser, convection streams will transport it efficiently to depth, but this may not be so.

Dynamical geochemistry of the mantle [PDF]
Solid Earth, 2011 Abstract. The reconciliation of mantle chemistry with the structure of the mantle inferred from geophysics and dynamical modelling has been a long-standing problem. This paper reviews three main aspects. First, extensions and refinements of dynamical modelling and theory of mantle processing over the past decade. Second, a recent reconsideration of the

EarthN: A new Earth System Nitrogen Model [PDF]
, 2018 The amount of nitrogen in the atmosphere, oceans, crust, and mantle have important ramifications for Earth's biologic and geologic history. Despite this importance, the history and cycling of nitrogen in the Earth system is poorly constrained over time ...

The Depositional Record, EarlyView.The Upper Permian Castile Formation of the Delaware Basin, a 515.3 m (1690.6 ft) thick deep‐water evaporitic sequence dominated by anhydrite and halite, is the focus of this study. This study's sedimentological and geochemical analysis of cores from the basin's centre and margin reveals that dynamic reflux of deep hypersaline brines significantly ...

The Depositional Record, EarlyView.A classical peripheral foreland basin is bounded longitudinally by a pair of marginal ocean basins (DeCelles & Giles, 1996). The WTFB sediments transfer to adjacent marginal ocean basins. The western Taiwan foreland basin (WTFB) is regarded as a classical peripheral foreland basin, longitudinally bounded by the southern Okinawa Trough (SOT) to the ...
