Geological rock types polygons (1:100,000)

Brief description

The data contains primary geological data, namely outcropping/sub-cropping geological rock units.

This layer has been superseded by the Seamless Geology layer - SG_GEOLOGICAL_UNIT_50K

The dataset is part of the geological mapping dataset, which includes datasets representing geological rock units and boundaries, structural lines, miscellaneous lines and points, miscellaneous polygons, metamorphism, and placer deposits.

The data have been collected by the Geological Survey of Victoria. Data have typically been captured in projects covering 1:100,000 mapsheets, and have typically been recorded in the field by hand at 1:25,000 then prepared for hard copy printing at 1:50,000.
