• The Seismic Signatures of Recently Formed Impact Craters on Mars 

  Schmerr, Nicholas; Banks, Maria; Daubar, Ingrid (Journal of Geophysical Research Planets, 2019-09)

  We investigated the seismic signatures of recent impact crater clusters on Mars that would be recorded by the InSight Seismic Experiment for Interior Structure (SEIS) seismometers. We used a database of 77 measured and ...

• Characterization of the regional, crustal, and global distribution and abundance of the heat producing elements and their geoneutrino flux 

  Wipperfurth, Scott Alan (2019)

  The amount and distribution of radiogenic power generation from the heat producing elements (HPE) U, Th, and K in the Earth is not well constrained. Compositional estimates of these elements vary by a factor of three in ...

• Origin of the anomalous sulfur isotope composition of the Rustenburg Layered Suite (Bushveld Complex), South Africa 

  de Assis Magalhaes, Nivea Maria (2019)

  The 2.06 Ga Bushveld Magmatic Province (BMP) hosts the largest platinum group element (PGE) reserve of the world that occurs mainly as sulfide-rich layers within the Rustenburg Layered Suite (RLS), and also in mineralized ...

• Stabilizing Effect of High Pore Fluid Pressure on Slip Behaviors of Gouge-bearing Faults 

  Xing, Tiange; Zhu, Wenlu; French, Melodie; Belzer, Ben (2019)

  We conducted experiments to investigate the influence of pore fluid pressure on the frictional strength and slip behavior of gouge bearing faults. Saw-cut porous sandstone samples with a layer of gouge powders placed between ...

• Constraints on Seismic Anisotropy in the Mantle Transition Zone from Long-Period SS Precursors 

  Huang, Quancheng; Schmerr, Nicholas; Waszek, Lauren; Beghein, Caroline (2019)

  The mantle transition zone (MTZ) of Earth is demarcated by solid-to-solid phase changes of the mineral olivine that produce seismic discontinuities at 410 and 660 km depths. Mineral physics experiments predict that wadsleyite ...
