Lines in this cover show where gravity oe aeromagnetic data have beenmodelled to constrain subsurface structure. Gravity andmagnetic signatures result from deep structure, such as might be athypocentral depths of earthquakes. We show only the lines for whichinterpretations or models are publically available. In gravmag_all,extent of the lines outside the study boundary is retained;in gravmag the lines have been clipped to the study boundary.
