Euler rotations in plate-tectonic reconstructions

Euler rotations describe the motions of rigid plates on a sphere and can be used to perform paleogeographic reconstructions and to compare paleomagnet ic data from different continents. The properties and mathematical equation s for these rotations are summarized. Subroutines and example programs in T urbo Pascal that perform Euler rotations and calculate angular velocities a nd relative plate velocities are presented. (C) 1999 Elsevier Science Ltd.
