Structural Characterization of the Taltal Segment in Northern Chile Between 22°S and 26°S Using Local Earthquake Tomography
-  24 May 2024
Key Points
Seismic catalog reveals forearc activity and slab dip variations. Vp anomalies in the oceanic plate are related to mid-depth seismic events
Velocity models uncover anomalies in Salar de Atacama and Taltal ridge that might influence seismicity distribution and hydration changes
Shallow low Vp/Vs (<1.75) correlate with ore deposits; deep high Vp/Vs (>1.80) suggest fluids and melting for the Lastarria volcanic complex
Combustion Completeness and Sample Location Determine Wildfire Ash Leachate Chemistry
-  21 May 2024
Key Points
Stalagmites record past fire activity through changes in inorganic and organic chemistry sourced from ashes
Wildfire ash leachate chemistry will aid interpretation of proxy fire data
Results show that inorganic chemistry varies with burn severity and sample location, and the pyrogenic biomarker signal is less clear
Characterizing Natural Hydrogen Occurrences in the Paris Basin From Historical Drilling Records
-  21 May 2024
Key Points
Natural hydrogen exploration in former oil and gas province
Use of the Optical Character Recognition algorithm to optimize processing of a large drilling report database
Indices for a potential H2 system (source, migration, trap) in the Paris Basin
Sphalerite Records Cd Isotopic Signatures of the Parent Rocks in Hydrothermal Systems: A Case Study From the Nayongzhi Zn–Pb Deposit, Southwest China
-  19 May 2024
Key Points
S isotopic variations caused by Rayleigh fractionation between sulphide and reduced S; Cd isotopic variations inherited from source rocks
Zn/Cd ratios and Cd isotopic compositions reveal that Zn and Cd were dominantly derived from basement rocks
The Nayongzhi deposit was formed by mixing between metal-rich and reduced sulfur ore-forming fluids
Morphology‐Dependent Magnetic Properties in Shallow‐Water Ferromanganese Concretions
-  16 May 2024
Key Points
Magnetic minerals within shallow water Fe-Mn concretions can provide valuable environmental information about their formation
Magnetic properties are linked to specific growth patterns in Baltic Sea Fe-Mn concretions
Spheroidal and crust/discoidal concretions are dominated by biogenic and pedogenic magnetic phases, respectively
Sulfide Melt Wetting Properties in Earth's Mantle: New Constraints From Combined 2D and 3D Imaging
-  15 May 2024
Key Points
The mobility of mattes is enhanced by majoritic garnet at sub-lithospheric depths
The combination of 2D and 3D methods improves our understanding of liquid percolation in the Earth's mantle
Origin of Philippine Sea Basins During Subduction Initiation in the Western Pacific
-  14 May 2024
Key Points
New dating indicates that a major part of the oldest Philippine Sea Plate basins formed after c. 51 Ma
Ocean crust of the oldest Philippine Basins is affected by the Oki-Daito mantle plume
Onset of spreading of the West Philippine Basin could have been triggered when the Oki-Daito plume hit the base of preexisting lithosphere
Delamination Magmatism in Eastern Anatolia: A Geochemical Perspective
-  14 May 2024
Key Points
During Neo-Tethyan subduction, pyroxenite-bearing domains formed by melt intrusion into the lower lithosphere beneath Eastern Anatolia
The pyroxenite-bearing domains resulted in gravitational instabilities and led to the foundering of the lithosphere in the Late Miocene
The regional post-collisional volcanics represent the melts derived both from asthenospheric and delaminated lithospheric mantle domains
Geomagnetic Field Intensity During the First Millennium BCE From Royal Judean Storage Jars: Constraining the Duration of the Levantine Iron Age Anomaly
-  13 May 2024
Key Points
Archaeomagnetic intensity data from 32 groups of pottery in Israel dated between the 7th and the 1st centuries BCE
The second generation of the Levantine Archaeomagnetic Curve (LAC.v.2.0) covering the last three millennia BCE
The new data constrain the duration of the Levantine Iron Age Anomaly (LIAA) from 1100 BCE to 550 BCE
Magmatic Controls on Volcanic Sulfur Emissions at the Iceland Hotspot
-  13 May 2024
Key Points
Maximum eruptible S contents (ppm S) are estimated for 73 Icelandic eruptions based on melt inclusion data
Pre-eruptive S contents are mostly controlled by sulfide saturation during both melting and crustal magmatic differentiation
Icelandic basalts often erupt at compositions close to a compositional maximum in sulfide solubility, leading to relatively high S emissions
