During the past 20 years, numerous oceanographic surveys have mapped the age of the ocean floor in great detail (NGOC data bank). Recently, two separate studies have compiled these results and have produced maps illustrating the age of the ocean basins on a global scale (Sclater and Parsons, 1981; Larson et al., 1985). This work has been done with the realization that in order to make accurate plate tectonic reconstructions, an accurate map of the age of the ocean floor is required. This report compares these two compilations and presents a new set of Mesozoic and Cenozoic plate reconstructions based on the magnetic isochrons of Larson et al.
