TL;DR: Inverse convection models have identified two prominent seismic anomalies on the recovered Farallon plate as mentioned in this paper, and these seismic anomalies coincide palaeogeographically with the restored positions of the Shatsky and Hess conjugate plateaux as they subducted beneath North America.

TL;DR: In this article, the electronic environment of the Fe nuclei in two silicate perovskite samples, Fe_(0.05)Mg/(0.95)SiO_3 (Pv05) and Fe(0.9)Si O_3(Pv10), were measured to 120 GPa and 75 GPa, respectively, at room temperature using diamond anvil cells and synchrotron Mossbauer spectroscopy (SMS).

TL;DR: The sound velocities of (Mg_(16)Fe_(84))O have been measured to 121 GPa at ambient temperature using nuclear resonant inelastic x-ray scattering in situ using synchrotron Mossbauer spectroscopy as mentioned in this paper.

TL;DR: In this article, the effect of electronic environment of the iron sites on the sound velocities were tracked in situ using synchrotron Mossbauer spectroscopy, and it was shown that only a small amount of iron-rich (Mg,Fe)O can greatly reduce the average sound velocity of an assemblage.

TL;DR: The geometry and properties of the Cocos plate beneath central Mexico are determined from the receiver functions (RFs) utilizing data from the Meso America Subduction Experiment (MASE) as discussed by the authors, where the subducting oceanic crust is shallowly dipping to the north at 15° for 80 km from Acapulco and then horizontally underplates the continental crust for approximately 200 km to the Trans-Mexican Volcanic Belt (TMVB).
