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.
