Application of Bingham statistics to a paleopole data set

paleopole locations are few and far between, paleo-magnetists have had no choice but to connect the poles by straight lines, which at best may reflect a highly smoothed path Fig 1a In addition, if the ages of the poles are poorly known, the younging direction of the path may be poorly constrained Paleomagnetic poles are typically plotted


PALEOMAGNETIC POLES - Geosciences

Paleomagnetism: Chapter 7 122 Calculation of a pole position is a navigational problem in spherical trigonometry that uses the dipole formula (Equation (1 15)) to determine the distance traveled from observing locality to pole position

complicates the definition of a confidence interval for the obtained paleopole locations, and previously estab-lished methods cannot be applied [3,8] Therefore, we will here choose a confidence limit corresponding to three times the minimum misfit as a threshold for ad-missible paleopole locations

declination= 43°, inclination= -3° (α95= 12°) The paleopole position for the 1 76 Ga age is 45°N, 199°E (A95=10°) We also present a possible continental reconstruction for ~1 77 Ga, which shows some similarities with previously published models, but due to the lack of poles at this age, we cannot adequately test a complete reconstruction

paleopoles: meaning origin definition - WordSense Dictionary

The term paleomagnetic pole implies that the pole position has been determined from a paleo- magnetic data set that has averaged geomagnetic secular variation and thus gives the position of the rota- tion axis with respect to the sampling area at the time the ChRM was acquired
