GIS datasets
The Geological Survey of Queensland (GSQ) compiles GIS information packages that feature major regional studies reports. However, if errors are fixed or maps are updated after their release, the packages are not usually updated to reflect those changes. It may therefore be advantageous to purchase both the GIS information package and digital geological mapping data which contains more up-to-date information.
While GIS were built using now superseded versions of ESRI and MapInfo software, the shape and tab files are still compatible. ESRI versions were assembled using ArcView 3.2, so when ArcView (.apr) project files are imported into ArcMap, the colour symbolisation of geological units does not completely convert. There may also be issues with workspace (.wor) files in MapInfo.

North Queensland gold and base metals study
The North Queensland gold and base metals study was conducted in two stages. The first stage covered the Georgetown (Etheridge and Croydon) region and the second stage covered the Charters Towers region.
The reinterpretation of data for these regions involved a desktop analysis using geophysical data acquired through original mapping, followed by limited field checking of significant geological revisions.
Stage 1: Georgetown (November 2002)
The North Queensland Gold and Base Metals Study, Georgetown, is an integrated digital geological information package for the Georgetown area.
The Georgetown area is most prospective for epithermal gold systems, the Broken Hill type base metal mineralisation model, Kidston-Mount Leyshon type gold model, and possibly Carlin style mineralisation.
What data is included?
Datasets in the product include:
- geology and explanatory notes
- mineral occurrences
- geophysical images
- interpreted magnetic lineaments
- whole rock geochemistry
- geological field observations
- historic exploration tenure
- solid geology interpretation (excluding alluvium, soils, regolith and Mesozoic age rocks).
Data coverage
The data covers the following 1:100,000 map sheets:
- Lyndbrook
- Bullock Creek
- Croydon
- Gilbert River
- Forest Home
- Georgetown
- Mount Surprise
- Saint Ronans
- Prospect
- Esmeralda
- North Head
- Forsayth
- Einasleigh
- Conjuboy
- Pelham
- Bellfield
- Gilberton
- Lyndhurst
- Burges
- Etherdale
- Mount Norman
- Hampstead.
Data format
The data is supplied in both ArcView and MapInfo formats.
Stage 2: Charters Towers (November 2003)
The North Queensland Gold and Base Metal Study, Charters Towers, is an integrated digital geological information package for the Charters Towers area.
The Charters Towers area is most prospective for mesothermal granite-hosted veins (Charters Towers), intrusive-related, breccia-hosted (Mount Leyshon), and mesothermal multiphase vein (Nolan's-Sarsfield) gold deposit styles and volcanic-hosted massive sulphide deposit styles (Highway, Reward and Thalanga).
What data is included?
Datasets in the product include:
- geology (surface and basement) and explanatory notes
- mineral occurrences
- geophysical images
- interpreted magnetic lineaments
- geological field observations
- whole rock geochemistry
- exploration geochemistry sample locations
- topographic map themes
- historic exploration tenure
- basement geology interpretation (excluding alluvium, soils, regolith and some Mesozoic age rocks).
Data coverage
The data covers the following 1:100,000 map sheets:
- Conjuboy
- Valley of Lagoons
- Kangaroo Hills
- Ingham
- Palm Islands
- Burges
- Clarke River
- Ewan
- Rollingstone
- Townsville
- Chudleigh Park
- Wandovale
- Maryvale
- Hillgrove
- Dotswood
- Mingela
- White Mountains
- Lolworth
- Homestead
- Charters Towers
- Ravenswood
- Pentland (part of).
Data format
The data is supplied in both ArcView and MapInfo formats.
