Abstract
A new 460 km long transect combines 6-12 fold explosive and 60 fold vibroseis data, proving that it is possible to re-use old, low fold seismic data by utilizing new processing techniques. We demonstrate comparability in resolution of reprocessed dynamite and new vibroseis data. Reprocessing of the dynamite data using a vertical stacking technique that simulates DMO corrections, followed by detailed velocity analysis, has resulted in an improved seismic section that images dipping structures not detected in the original processing.A new 460 km long transect combines 6-12 fold explosive and 60 fold vibroseis data, proving that it is possible to re-use old, low fold seismic data by utilizing new processing techniques. We demonstrate comparability in resolution of reprocessed dynamite and new vibroseis data. Reprocessing of the dynamite data using a vertical stacking technique that simulates DMO corrections, followed by detailed velocity analysis, has resulted in an improved seismic section that images dipping structures not detected in the original processing. Several deep penetrating shear zones in the Broken Hill block dip mostly to the SE, and link to a shallow thrust belt located further to the west. Because of the large depth of penetration, these shear zones may have conducted fluids from deeper levels, which has important implications for mineral exploration.
