==Abstract==

The possibility of a link between asymmetrical Earth?s expansion and Polar Motions is   investigated, searching for possible mechanisms of inner and/or surface material displacement, which   can lead to the observed Chandler Wobble (CW; eulerian free oscillation) and its secular drift. While a   main result of this work is the individuation of the possible cause of PM in the diffuse emplacement of   new mass in and under the triple point zones, the problem of the continuous excitation of the CW is   still not resolved, and only a qualitative argument is proposed. The result is found that the PM?s actual   parameters can be prolonged in the geological past, reproducing with satisfactory approximation the   more reliable True Polar Wander path up to 100 Ma, and its slowing down and inversion of walk   around 50 Ma.
