The PI will update and analyze paleomagnetic data for the               last five million years to carry out robust statistical analyses                on the polarity asymmetry problem and to determine the origin of                the latitudinal variation of paleosecular variation.  Preliminary               analyses indicate that there is some discernible polarity                       asymmetry for the mean field ata (and only mean field data).                    The possibility that this asymmetry is due to thermal electric                  effects in the seismic D" region will be examined.  Analyses of                 the present field using procedures analogous to those used by                   paleomagnetists in paleosecular variation studies of lava flows                 indicate a method by which for the first time the dipole and                    quadrupole families of dynamo theory can be distinquished by                    analyzing paleomagnetic data.  Detailed analyses will be carried                out using an updated data set for rocks with ages less than five                million years.  If successful for this period of time, the                      methods will be applied to updated data going back in time to                   the Cretaceous.
