COLD CRATONIC ROOTS AND THERMAL BLANKETS: HOW CONTINENTS AFFECT MANTLE CONVECTION

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 ...
CONTINENTS AS LITHOLOGICAL ICEBERGS: THE IMPORTANCE OF BUOYANT LITHOSPHERIC ROOTS

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 ...
EXTRATERRESTRIAL INFLUENCES ON MANTLE PLUME ACTIVITY

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 ...
THE INSTENSITY, OCCURRENCE, AND DURATION OF SUPERPLUME EVENTS AND ERAS OVER GEOLOGICAL TIME

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 ...
