Abstract

The Australian Crustal Elements dataset delineates upper crustal elements, primarily based on composite geophysical domains, each of which shows a distinctive pattern of magnetic and gravity anomalies. These elements generally relate to the basement, rather than the sedimentary basins. Boundaries between these elements are interpreted to mark crustal-scale changes in composition or structural pattern, or both. Where feasible, these boundaries are chosen to emphasise their correlation with the outcropping boundaries of geological provinces.

Lineage

Crustal element interpretation of current gravity and magnetics image data was digitised initially in Microstation (Integraph) and subsequently ported into Arcinfo, dictating the gravity, magnetic and resultant polgyon coverage of crustal elements. Attributes were added to the polgon and arc coverages after this. Gravity data 1.National Gravity Database derivative integrated ' 2.5km (91.5 minute) gridded format' 2.Contoured Bouger anomaly contour maps plotted at ' 1:2 500 000 scale' 3.Enhanced images of Bouger anomalies at 1:5 000 000 scale Magnetics data 1.National Magnetics Database derivative 1:1 000 000/1:2 500 000 ' scale contour maps' 2.Various scale anomaly images 3.Magnetic Anomaly 1:5 000 000 scale map of Australia, showing ' gradient enhanced residuals of total intensity'
