Becker T.W.; Kellogg J.B.; Ekström G.; O'Connell R.J. (2003)We present global models of strain accumulation in mantle flow to compare the predicted finite-strain ellipsoid (FSE) orientations with observed seismic anisotropy. The geographic focus is on oceanic and young continental ...

Kellogg J.B.; Jacobsen S.B.; O'Connell R.J. (2002)We present an extension of the conventional geochemical reservoir model for the evolution of the Earth's crust-mantle system in which we calculate not only the mean isotopic ratios, but also the distribution of those ratios ...

Becker T.W.; Kellogg J.B.; O'Connell R.J. (1999)Geochemical models have frequently divided the mantle into depleted upper and undepleted lower mantle reservoirs, usually taken as indication for a layered style of convection. This is difficult to reconcile with seismological ...

Rudnick R.L.; McDonough W.F.; O'Connell R.J. (1998)Global compilations of surface heat flow data from stable, Precambrian terrains show a statistically significant secular change from 41±11 mW/m2 in Archean to 55±17 mW/m2 in Proterozoic regions far removed from Archean ...
