Dataset: CLM - Main Range volcanics



The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

This shapefile shows the extent of the Main Range Volcanics in the CLM bioregion. It is compiled from several data sources, including Qld and NSW surface geological maps and well data. In many areas, the exact extent is not well constrained, as this bedrock unit is covered by younger rocks or sediments. Where this is the case, the available data have been combined with geological expert knowledge to infer the likely extent in the subsurface.

Dataset History

The shapefile is based on the digital 1:100000 surface geology map sheet (Qld Geological Survey) and 1:250000 surface geological map obtained from the Clarence-Moreton SEEBASE project in NSW (see lineage). The final shapefile has been created from all sources and expert knowledge in GoCAD.
