# Hatches Creek Region, Northern Territory 1:100 000 geological map, Special

## Identification

Abstract:

GIS dataset for the Hatches Creek Region 1:100 000 outcrop geology map sheet.

These data are a digital version of information depicted on the printed map from the 1:100 000 Geological Series produced by the Bureau of Mineral Resources (BMR), now Geoscience Australia (GA) and the Northern Territory Geological Survey (NTGS).

The Hatches Creek Region Geology 1:100,000 Map has been modified to conform to the current NTGS Data Dictionary and symbology standards.

## Data Quality and Status

Lineage:

The geological maps are a depiction of information acquired from interpretation (mostly air photography), field observation, and subsequent investigation (e.g. sample analysis for age and rock-type determination). Some detail may have been generalised, repositioned, or omitted from the primary data for cartographic purposes. Maps were compiled from Airphoto interpretation, Landsat TM interpretation, fieldwork, literature research, thin section petrography, geochemical analysis, geochronology and geophysical interpretation.

The dataset is comprised of several layers including outcrop lithology, faults, folds, linear features, geochronology, structural data, and mineral occurrences.

Positional Accuracy: ± 200 metres

Spatial Resolution: Data digitized from scanned image of the Geology of the Hatches Creek Region 1:100 000.

Attribute Accuracy:

Variable, high accuracy of attributes in areas visited (ie most outcropping geology), lower accuracy in those areas not visited. Data is checked visually on plots and for topological consistency using in-house routines and MapInfo software. As much as possible, every effort has been made to ensure that the accuracy and standards of the source maps have been maintained.

The NTGS modified data conforms to current NTGS Data Dictionary, file naming conventions and symbology standards.

In some cases (e.g. the age, name and genealogy of stratigraphic units), information may be outdated and may also be inconsistent between map sheets. The latest information is often available in various GA and/or NTGS databases, e.g. the GA Stratigraphic Names database, but this has not been incorporated into NT geology map sheets at this time.

The frequency of measured sites on maps, e.g. dips of bedding etc., is a reasonable indicator of field activity/verification. More information can be found in Explanatory Notes which were produced in conjunction with the geological maps.
