Lineage:
This is the first edition of a 1:100 000 geological map of Gove (6273) and part of Arnhem (6173). This 1st edition map used the earlier 1:250 000 scale maps of Arnhem Bay (SD 53-03) and Gove (SD 53-04) 1:250 000 map data as a base. This was complemented by geological mapping fieldwork, literature research, thin section petrography, geochemical analysis, geochronology, structural analysis, and geophysical interpretation. This was complemented by fieldwork, literature research, thin section petrography, geochemical analysis, geochronology, structural analysis, and geophysical interpretation.
Mapping combination of 30 cm resolution, colour aerial photographs flown in 2013 and Google Earth imagery.
The dataset is comprised of several layers including outcrop lithology, faults, folds, linear features, geochronology, structural data, and mineral occurrences.
Positional Accuracy: 15 to 100 metres
Spatial Resolution: Mapped at 1:25,000 to produce 1:100,000 map
Attribute Accuracy:
Variable, high accuracy of attributes in areas visited (ie most outcropping geology), lower accuracy in those areas not visited. The geochronological data comes from samples analysed by geochronologists from Geoscience Australia, NTGS, researchers and analytical laboratories operating in collaboration with NTGS, and from published literature; dataset has been checked against the original source. All mineral occurrences are attributed by metallogenic geologists with experience in the Northern Territory; some attributes (eg model) are interpretative rather that descriptive. Geochemical analysis is performed by laboratories to set standards. Standard uncertainty on structural measurements is 1 degree. Compass directions are quoted with respect to Grid North.
