Hotspots and Mantle Plumes' Some Phenomenology
- N. Sleep
- Environmental Science, Geology
- 10 May 1990
The available data, mainly topography, geoid, and heat flow, describing hotspots worldwide are examined to constrain the mechanisms for swell uplift and to obtain fluxes and excess temperatures of…

Carbon dioxide cycling and implications for climate on ancient Earth
The crustal Urey cycle of CO2 involving silicate weathering and metamorphism acts as a dynamic climate buffer. In this cycle, warmer temperatures speed silicate weathering and carbonate formation,…
Cenozoic magmatism throughout east Africa resulting from impact of a single plume
- C. Ebinger, N. Sleep
- GeologyNature
- 22 October 1998
The geology of northern and central Africa is characterized by broad plateaux, narrower swells and volcanism occurring from ∼45 Myr ago to the present. The greatest magma volumes occur on the…

Emergence of a Habitable Planet
Abstract
We address the first several hundred million years of Earth’s history. The Moon-forming impact left Earth enveloped in a hot silicate atmosphere that cooled and condensed over ∼1,000 yrs. As…
