This download package contains the 2015 Pedirka Basin Seismic Mapping project. The data is available in ASCII, Petrosys and Shapefile formats. This dataset contains grid and contour files of depths and isopachs to significant seismic horizons over the Pedirka Basin in South Australia and the Northern Territory, along with the associated fault and polygon files. Seismic Horizons -------------------- CP – Top Crown Point Fm. P – Top of Permian Sediments PU – Top Purni Fm. Z – Top Basement Horizons Mapped --------------------- CPd – Top Crown Point Fm. Depth Pd – Top Permian Sediments Depth PUd – Top Purni Fm. Depth Zd – Top Basement Depth CPi – Crown Point Fm. Isopach PUi – Purni Fm. Isopach PZi – Permian to Basement Isopach Depths are in metres below MSL datum. Grid, Contour, Fault & Polygon format details can be found in the file pedirka_format.pdf. Data projected in LAMBERT Conformal Conic - Southern Hemisphere Projection - Lambert Conformal Conic (SA Lambert) Spheroid - GRS80 Datum - GDA94
