A hypothesis for Proterozoic-Phanerozoic supercontinent cyclicity, with implications for mantle convection, plate tectonics and Earth system evolution [PDF]

open access: yes, 2015
We present a conceptual model for supercontinent cycles in the Proterozoic-Phanerozoic Eons. It is based on the repetitive behavior of C and Sr isotopes in marine carbonates and U–Pb ages and εHf of detrital zircons seen during the Neoproterozoic ...

Mesoproterozoic paleogeography: Supercontinent and beyond [PDF]

open access: yes, 2013
A set of global paleogeographic reconstructions for the 1770–1270 Ma time interval is presented here through a compilation of reliable paleomagnetic data (at the 2009 Nordic Paleomagnetic Workshop in Luleå, Sweden) and geological constraints.

Palaeomagnetic, geochronological and geochemical study of Mesoproterozoic Lakhna Dykes in the Bastar Craton, India: Implications for the Mesoproterozoic supercontinent [PDF]

open access: yes, 2013
Palaeomagnetic analysis of the Lakhna Dykes (Bastar Craton, India) yields a palaeopole at 36.6°N, 132.8°E, dp=12.4°, dm=15.9°, and the U--Pb zircon age obtained from one of the rhyolitic dykes is 1466.4±2.6 Ma (MSWD=0.21, concordia age based on two ...

SGLOBE‐Q2D: A Global 2‐D Model of Fundamental and Higher Mode Rayleigh Wave Attenuation From a Large Amplitude Data Set

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract We present SGLOBE‐Q2D, a global upper mantle model of frequency‐dependent Rayleigh wave attenuation with uncertainties. We use a data set of ∼ ${\sim} $10 million fundamental and higher mode (up to 4th overtone) Rayleigh wave amplitude measurements with wave periods T∼ ${\sim} $38–275 s.
