Seeing more of the Nullarbor basement

摘要

As part of the Western Australian Government's Royalties for Regions Exploration Incentive Scheme (EIS), the Geological Survey of WA (GSWA) has released the Seemore airborne geophysical survey. This is the first of a series of surveys at 200 metre line spacing that will cover the Eucla Basin. At half the usual spacing of GSWA's regional surveys, this latest release gives a remarkably detailed picture of Proterozoic basement rocks buried beneath sand and the relatively thin Cenozoic limestones of the Nullarbor Plain.
