Mineral physics of the mantle [PDF]

open access: yes, 1995
The last few years have seen intense interest in the global environment and climate change, and with it an increasing appreciation for the interactions between the atmosphere, biosphere, oceans and the solid earth.

Sr-Nd-Pb-Hf isotope results from ODP Leg 187: Evidence for mantle dynamics of the Australian-Antarctic Discordance and origin of the Indian MORB source [PDF]

open access: yes, 2002
New high precision PIMMS Hf and Pb isotope data for 14–28 Ma basalts recovered during ODP Leg 187 are compared with zero-age dredge samples from the Australian-Antarctic Discordance (AAD).

Mantle structure and tectonic history of SE Asia [PDF]

open access: yes, 2015
Seismic travel-time tomography of the mantle under SE Asia reveals patterns of subduction-related seismic P-wave velocity anomalies that are of great value in helping to understand the region's tectonic development.

Mantle transition zone thickness beneath Ross Island, the Transantarctic Mountains, and East Antarctica

open access: yesGeophysical Research Letters, 2008
The thickness of the mantle transition zone beneath Ross Island, and parts of the Transantarctic Mountains and East Antarctic Craton has been mapped using data from the 2000–2003 Transantarctic Mountain Seismic Experiment to determine if, as indicated by

Earthquake in central Italy and velocities structure of the mantle

open access: yesГеофизический журнал, 2018
A three-dimensional P-velocity model of the European mantle built on the Taylor approximation made it possible to analyze the velocity structure of the mantle under the Mediterranean and, in particular, under Central Italy, to a depth of 2500 km. It is

Investigation of Petrological Characteristics of The Upper Mantle in Hadji-Abad Ophiolitic Complex (South of Iran): Based on Mineral Chemistry [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2021
The mantle peridotites of the Hadji-Abad ultramafic complex in Hormozgan province, show some petrological evolutions of the upper mantle of southern Iran. The complex includes harzburgite, lherzolite, dunite and chromitite.

P-wave velocities of the upper mantle of the Tethysalpine geosynclines

open access: yesГеофизический журнал, 2020
The aim of the work is to calculate the velocity distribution of the longitudinal seismic waves (VP) in the upper mantle at depths from the discontinuity M to 400 km.

Atlas of the underworld: Slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity [PDF]

open access: yes, 2018
Across the entire mantle we interpret 94 positive seismic wave-speed anomalies as subducted lithosphere and associate these slabs with their geological record.

Characterization of Viscous Dissipative Heating in the Earth's Mantle Caused by Surface Forces

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Viscous dissipative heating has long been discussed as a heat source in solid celestial bodies experiencing exogenic forces such as tidal forcing or surface loading.
