[Geodynamics] Hotspots and true polar wander at the Fall AGU Meeting

[Richard G. Gordon]

Dear colleagues,

Please consider submitting an abstract about your research into motion 
between hotspots, true polar wander, mantle convection, paleomagnetic 
apparent polar wander paths, or related topics to the following session:

GP008: Motion Between Hotspots and True Polar Wander

In a convecting planet, mantle plumes and their surface manifestations, 
hotspots, doubtless are in relative motion. Past estimates of rates of 
motion between hotspots span an enormous range, however, from as low as 
~3 mm/yr to as high as ~80 mm/yr. Paleomagnetic investigations have 
established that some hotspots have moved significantly relative to the 
spin axis, which was originally interpreted as evidence for true polar 
wander, the motion of the entire solid Earth relative to the spin axis. 
Some later investigations have argued that the motion records true polar 
wander while other investigations argue that it records motion of 
hotspots relative to one another and relative to the deep mantle. 
Recently new evidence has been presented supporting both relatively slow 
motion between hotspots on the one hand and rapid motion between 
hotspots on the other. We encourage submissions related to any and all 
aspects of these phenomena.
