This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.
This dataset is produced by the Seamless Geology project. The data represents the surface geology, including surficial unconsolidated deposits and outcropping (or near-outcropping) bedrock, geological unit contacts, faults and shear zones. The project was compiled in stages, based on the structural zones of Victoria (2006-2014).
Some of the supplied data contains geological lithology and age information which is a complex relationship (ie. one to many). Geological units may have multiple lithologies or event ages. This relationship is established in the ESRI MXD file found in the ESRI Geodatabase ver 9.3 folder. To apply this to the shapefile/mapinfo files requires software that is capable of creating a one to many relationship between fields. This can be established between the GEOGRAPHIC field (in any shapefile/mapinfo with a GEOLUNIT prefix in the name) and the GEOGRAPHIC field in either/or both the GEOLOGICALAGE and LITHOLOGY tables.
To provide a seamless geological interpretation of the surface geology of Victoria. Geometry and attribution will be reconciled at scale and across scales for 1:50 000 and 1:250 000. Geology of suitable quality collected in the pre-digital era (e.g. 1 to 1 mile maps) will supplement the more recent data in the 50k or 250k layers. The project will generalise the reconciled 50k geological mapping into the 250k geology.
No description on the lineage of the datasets was provided. Comprehensive metadata is available at the feature class level within the dataset.
