Time constraints on the formation of lithospheric mantle beneath cratons: a re-Os isotope and platinum group element study of peridotite xenoliths from northern Canada and Lesotho, [PDF]
Understanding the generation and evolution of cratonic lithospheric keels requires detailed knowledge of their age, timescale of formation, and the relationship between the crust and mantle part of the lithosphere.

Ridge Migration and Plate Boundary Readjustments at the Rodriguez Triple Junction
Abstract The Rodriguez Triple Junction (RTJ) marks the intersection of the Indian Ocean's three principal mid‐ocean ridges and is a type locality for Ridge‐Ridge‐Ridge triple junctions. A local seismic network was deployed for 8 months to monitor seismicity around the RTJ and the adjacent Central Indian Ridge (CIR).

An Equivalent Source Method for Modelling the Lithospheric Magnetic Field Using Satellite and Airborne Magnetic Data [PDF]
We present a technique for modelling the lithospheric magnetic field based on estimation of equivalent potential field sources. As a first demonstration we present an application to magnetic field measurements made by the CHAMP satellite during the ...

Geomagnetic data from the GOCE satellite mission
The Gravity field and steady-state Ocean Circulation Explorer (GOCE) is part of ESA’s Earth Explorer Program. The satellite carries magnetometers that control the activity of magnetorquers for navigation of the satellite, but are not dedicated as science

Abstract The North Qiangtang Block occupies a pivotal position within the eastern Tethyan realm, and its paleogeographic reconstruction is critical for constraining Tethyan geometry and evolution. However, its Late Paleozoic paleogeography and Paleo‐Tethyan Ocean–continent configuration remain controversial due to limited reliable age‐constrained ...

Abstract We present the results of the first geological mapping of the western half of the Eminescu Quadrangle (H09) on Mercury. Multiple data sets from the NASA MESSENGER Mercury Dual Imaging System instrument were used to produce a geological map covering the area between 72°E and 108°E longitude and 22.5°N and 22.5°S latitude.
