Trubitsyn V.P.; Mooney W.D.; Abbott D.H. (2003)Two-dimensional convection models with moving continents show that continents profoundly affect the pattern of mantle convection. If the continents are wider than the wavelength of the con-vection cells (~3000 km, the ...

Abbott D.H.; Drury R.; Mooney W.D. (1997)An understanding of the formation of new continental crust provides an important guide to locating the oldest terrestrial rocks and minerals. We evaluated the crustal thicknesses of the thinnest stable continental crust ...

Abbott D.H.; Isley A.E. (2002)We use time series analysis to compare the impact histories of the Earth and Moon with the record of mantle plume activity. We use events with errors in their ages of =<150 Ma. The terrestrial and lunar impact records, ...

IMPLICATIONS OF THE TEMPORAL DISTRIBUTION OF HIGH-MG MAGMAS FOR MANTLE PLUME VOLCANISM THROUGH TIME Isley A.E.; Abbott D.H. (2002)We compile a 3.7-b.yr.-long time series of ultramafic and mafic rocks including extrusives and shallow intrusives (dikes and sills). We infer that peaks in the time series represent mantle plume events. Rocks erupted from ...

Abbott D.H.; Isley A.E. (2002)We define the characteristics of plume events that can be called superplumes. Using the surface area of the smallest oceanic plateau generated during the Cretaceous superplume era, we define a cutoff surface area for ...
