Evaluating the performance of machine-learning-based phase pickers when applied to ocean bottom seismic data: Blanco oceanic transform fault as a case study [PDF]

arXiv
Machine-learning-based phase pickers have been successfully leveraged to build high-resolution earthquake catalogs using seismic data on land. However, their performance when applied to ocean bottom seismic (OBS) data remains to be evaluated. In this study, we first adopt three machine-learning-based phase pickers - EQTransformer, Pickblue, and ...

Low Viscosity of Peridotite Liquid: Implications for Magma Ocean Dynamics

Geophysical Research Letters
Transport properties of silicate melts control magma ocean dynamics on the early terrestrial planets and rocky exoplanets. Here we calculate the viscosity (transport of momentum) of peridotite liquid at potential magma ocean conditions (0–159 GPa, 2,200 ...

Effects of mineral mode and textural variation on the seismic anisotropy in lithospheric mantle: an example from Horoman peridotites

Earth, Planets and Space
We performed a numerical analysis of seismic velocities in mantle peridotite using the elastic constants and crystallographic preferred orientations (CPOs) of olivine, orthopyroxene, and clinopyroxene. Proportions of olivine in the samples ranged from 50

Report on an open dataset to constrain the Balmuccia peridotite body (Ivrea-Verbano Zone, Italy) through a participative gravity-modelling challenge

Swiss Journal of Geosciences
The Balmuccia peridotite exposes relatively fresh mantle rocks at the Earth’s surface, and as such it is of interest for geologists and geophysicists. The outcrop is a kilometre-scale feature, yet its extent at depth is insufficiently imaged.
