This record contains the results of a project to develop a comprehensive GIS package focussed on the igneous rocks of northern Queensland (16.5 to 21 degrees S, 142.0 to 147.75 degrees E). The contracted work was undertaken as a joint project between the Australian Geological Survey Organisation (AGSO), Placer Exploration Ltd and the Queensland Department of Minerals and Energy (QDME). The aims of the contract work111were to: - Digitise all available geological maps of north Queensland and construct a multi-layeredGIS package of the igneous rocks of the designated region. - Characterise all igneous units in the region based on available petrographic and geochemical data (e.g. igneous type, degree of oxidation, degree of fractionation), andincorporate this classification as an ARC/INFO database. - Incorporate AGSO's ROCKCHEM and MINLOC data as ARC/INFO databases. - Fully document the GIS package, including a comprehensive bibliography of allclassified igneous rock units of the region.
