Data set for "Isotopic evidence for multiple recycled sulfur reservoirs in the Mangaia mantle plume"
In compliance with AGU's journal, "Geochemistry, Geophysics, Geosystems" we have uploaded the data collected for our manuscript titled "Isotopic evidence for multiple recycled sulfur reservoirs in the Mangaia mantle plume".
Isotopic Evidence for Multiple Recycled Sulfur Reservoirs in the Mangaia Mantle Plume
(American Geophysical Union, 2020-10-06)
Mangaia, an ocean island in the Cook-Austral volcanic chain, is the type locality for the HIMU mantle reservoir and has also been shown to exhibit evidence for recycled sulfur with anomalous δ34S and Δ33S that has been ...
RE-OS AND OXYGEN SYSTEMATICS OF VARIABLY ALTERED ULTRAMAFIC ROCKS, NORTH CAROLINA
This study focuses on the origin and modification of six ultramafic bodies located in the Blue Ridge Province of North Carolina. The bodies consist mainly of harzburgites and dunites with associated chromites. Some of the ...
SULFUR ISOTOPE CHARACTERIZATION OF MANTLE RESERVOIRS SAMPLED BY OCEAN ISLAND BASALTS
Ocean islands are volcanic islands in the middle of oceans that are formed when magma deep inside the Earth buoyantly rises to the surface and erupts as basaltic lava (termed Ocean Island Basalt, OIB). Geochemical ...
Planetary Seismology using Single-Station and Small-Aperture Arrays: Implications for Mars and Ocean Worlds
Studying geophysical station deployment on Earth is essential preparation for future geophysical experiments elsewhere in the solar system. Here, I investigated how single-station seismometers and small-aperture seismic ...
The Deployment of the Seismometer to Investigate Ice and Ocean Structure (SIIOS) in Northwest Greenland: An experiment to study icy ocean world seismic deployments
In anticipation of future spacecraft missions to icy ocean worlds, the Seismometer to Investigate Ice and Ocean Structure (SIIOS) was funded by NASA to prepare for seismologic investigations of these worlds. During the ...
Characterizing 3-dimensional Melt Distribution and Anisotropic Permeability in Sheared Partially Molten Rocks
With increasing shear strain, initially homogeneously distributed melt can segregate into an array of melt-rich bands, flanked by melt-poor regions. To address how the formation of these melt-rich bands affects the transport ...
THE GEOCHEMICAL BEHAVIOR OF SCANDIUM DURING FRACTIONAL CRYSTALLIZATION AND IMPLICATIONS FOR ORE FORMATION
Demand for scandium is increasing due to the use of scandium-aluminum alloys in the aerospace and sporting goods industries, and in solid-oxide fuel cells. Scandium deposits are associated with mafic intrusions and laterites, ...
Inference of Mass Anomalies in Planetary Interiors Using a Bayesian Global Gravity Field Inversion
Knowledge about the interior density distribution of a planetary body can constraingeophysical processes and reveal information about the origin and evolution of the body. Properties of this interior distribution can be ...
INSIGHTS TO THE GENETICS, AGE AND CRYSTALLIZATION OF GROUP IC AND IIC IRON METEORITES
Siderophile element isotopic compositions and abundances were determined for the IC and IIC iron meteorite groups to assess whether the members of each group can be related by crystal-liquid fractionation models, constrain ...
