Abstract
The GIS is based on the "Mount Isa Inlier and Environs" 1:500 000 scale map (published in 1987), which was digitised and verified against geochemical and mineral deposit point data. A series of interpretative geological and geochemical coverages were derived from these map data and point datasets such as ROCKCHEM, OZCHRON, and MINERAL DEPOSITS. Geophysical byte images provide broad regional views showing the concealed extent of the province.

Lineage
The source of the data was the 'Mount Isa Inlier and Environs' 1:500 000 scale map (published in 1987), which was digitised and verified against Geochemical and Mineral Deposit point data. Geological coverages based on the 1:500 000 geological map were geology, faults, folds, lineaments and frame. Derived geological coverages were solid geology, inlier outline, tectonic subdivisions and metamorphic zones. Coverages derived from AGSO's whole rock geochemistry database derived the average whole rock data within each polygon. Two sets of coverages are available, one as only sampled polygons having a value, and two all polygons have a value with the value for unsampled polygons being the average value for that unit. Several interpretive geological coverages are included in which geological units are classified according to dominant rock type, mineralogy, sedimentary sequence, granite type etc. Geophysical byte images from AGSO regional database are gravity and magnetics.
