Effects Of Subduction History On Mantle Convection: Implications For True Polar Wander And Dynamic Topography
… convection models and compares predictions of True Polar Wander (TPW), the geoid, and dynamic topography to observations. We explicitly calculate past mantle states using TERRA forward global geodynamic models that assimilate two different global plate reconstructions: a widely used model we …

Moving hotspots
… mantle of the Earth relative to the spin axis (true polar wander) or with a motion of the hotspot within the Earth’s mantle. Therefore, the possibility was studied whether true polar wander can be responsible for the difference between the paleomagnetic data and the present-day latitude of the …

Volatile Ice Deposits in Lunar Polar Regions and Their Sources
… results are produced without the use of the true polar wander theory. In addition to analysing water transport, this work simulates other volatiles observed in the LCROSS impact ejecta plume (H2S, CO2, NH3, CH3OH, C2H4). Analysis of volatile species simulations suggest photodissociation rates …

Palaeozoic Palaeomagnetism of South-Eastern Australia
… but remains largely unknown. Among the apparent polar wander (APW) paths published for Gondwana in the last few decades, large discrepancies exist (sometimes up to thousands of kilometres). The mid Palaeozoic segment of the APW path is particularly problematic, and two primary schools of thought …
