Abstract
The Coompana Project is a collaborative project between Geoscience Australia and the Geological Survey of South Australia, co-funded by Geoscience Australia’s Exploring for the Future Programme and the South Australian Government’s PACE Copper Initiative. The Coompana Project aims to provide new precompetitive geological, geophysical and geochemical data in the under-explored Coompana Province in South Australia. The pre-drilling geophysics program was undertaken to assist the drilling process by reducing the uncertainty associated with intersecting the targeted stratigraphy. Seismic data were acquired at eight proposed drilling sites for the Coompana Drilling Program in February 2017. Seismic data were collected using vertical and horizontal geophones. An accelerated weight-drop source was tested with metal and plastic strike plates. The plastic strike plate was preferred and used for all sites. Vertical geophone P-wave data were collected at all sites. At most sites fan shots from approximately 100 m perpendicular to the centre of the geophone spread were recorded. Far offset refractions shots were also recorded. Horizontal geophone S-wave data were acquired at five sites, including fan shots approximately 100 m perpendicular to the centre of the spread. The data release includes all seismic data recorded as SEG-2. The associated meta-data includes the a copy of the observer’s logs and coordinates files. The coordinates are presented as text files output for geophone station and source locations from the RTK or Garmin GPS systems. A README.txt file explains the ID column in the coordinates text files and details about the coordinates files. The shot and geophone station locations are also provided in KML format. The data acquisition is described in the supporting document: J. Holzschuh, M. Nicoll, S. R. B. McAlpine, M. Pawley, R. Dutch and T. Wise 2018.
