Brief description

This map of the Australian region shows the present day spreading asymmetry of the oceanic lithosphere. The spreading asymmetries are based on determining the percentage of crustal accretion between pairs of adjacent seafloor spreading isochrons by dividing the angular distance between them by the half-stage rotation angle.

Lineage

Grey areas indicate regions that are floored by continental or transitional crust or areas where the age or nature of the crust is unknown. White dots indicate locations of hotspots.


Resolution = 6 minute x 6 minute
Magnetometer data collected from ship track data is interpolated to densely spaced grids using a computer program Intertec developed at the University of Sydney.
