Layer 03 Great Artesian Basin base of Mackunda Formation and equivalents surface

Full description

Layer 03 Base of Mackunda Formation and equivalents surface

Surface produced for the Great Artesian Water Resource Assessment (GABWRA) by Geoscience Australia (http://www.ga.gov.au). This surface was created for 3D visualisation of the Base of Mackunda Formation and equivalents.

The surface is available in the following formats
1. GOCAD surface (.ts)
2. ESRI grid
3. ASCII grid (.grd)

Use limitations:
1. GOCAD surface requires program capable of reading GOCAD *.ts (triangulated surface) files
2. ASCII grid data requires re-interpolation by end-user resulting in minor differences to accompanying GOCAD *.ts surface

Statement: SOURCE DATA: Stratigraphic picks were sourced from exploration and stratigraphic drilling documented in PEPS-SA (South Australian Department for Manufacturing, Innovation, Trade, Resources & Energy, 2011), QPED database (Geological Survey of Queensland, 2010) and GABLOG database (Habermehl 2001). Seismic interpretation of Senior and Associates (1997) was used for contour constraints. BOUNDARIES: The layer boundary was modified from Habermehl and Lau (1997) / Welsh (2000) PROCESSING: For details on data processing, refer to "The three-dimensional visualisation of the Great Artesian Basin: A report to the Australian Government from the CSIRO Great Artesian Basin Water Resource Assessment" Nelson G. et. al 2012 REFERENCES: 1.
