Continental basalts commonly show ocean island basalts (OIB)-like geochemical
compositions, and their origin is geochemically linked to metasomatism of the big mantle …

Barium isotopes have been increasingly applied to trace igneous processes, but the
applications are hindered by the lack of equilibrium Ba isotope fractionation factors between …

Waters coproduced with hydrocarbons from unconventional oil and gas reservoirs such as
the hydraulically fractured Middle Devonian Marcellus Shale in the Appalachian Basin, USA …

Barium and its isotopes are receiving growing interest in their capacity to record the variation
of the oceanic biological pump through geological timescales. Nonetheless, only little is …

Barium (Ba) isotopes are a promising new tracer for riverine freshwater input to the ocean
and marine biogeochemical cycling. However, many processes that affect Ba cycling at …

This study presents a practical method for high precision Ba isotope measurement of barite
using the Na2CO3 exchange reaction and 135Ba–136Ba double-spike method by MC-ICP …

To investigate the potential of using Barium (Ba) isotopes to trace recycled crustal materials,
we report high-precision Ba isotopic compositions for 22 well-characterized samples of …

Mechanisms underlying barite precipitation in seawater and the precise depths of barite
precipitation in the water column have been debated for decades. Here we present a …

Marine shales, the most common lithology in the stratigraphic record, represent an archive of
long-term changes in sediment production, weathering intensity, and seawater chemistry …

We present a monthly resolved stable Ba isotope record (δ 138 Ba coral) of a young fossil
coral (Porites) from the eastern side of the Andaman Islands (NE Indian Ocean), which grew …
