Product description:Download The downloadable version of this report is supplied in PDF format. Introduction The Seamless Geology project has created seamless geological data at 1:250 000 scale across the entire state of Victoria, and seamless coverage at 1:50 000 scale of areas that have been mapped in detail. Eastern Victoria was the last region to be remapped for the project. The area covered included the Tabberabbera Zone, Omeo Zone, Deddick Zone, Kuark Zone and Mallacoota Zone (all within the Lachlan Fold Belt), and the younger rocks lying on top of these Palaeozoic tectonic zones. In creating a seamless geological map of Victoria, numerous map edge mismatches had to be addressed, often involving renaming of geological units as well as redrawing of unit boundaries based on airborne geophysics, aerial photos and topographic maps. Some units that cross into New South Wales had diff erent names on each side of the border and these have been renamed appropriately. Owing to time and budget constraints, there was no fi eldwork carried out for the project work in eastern Victoria. This means that several units have been given new names, following stratigraphic naming procedures, but type sections or localities have not been nominated. In addition, some areas, such as the Mallacoota Zone, need much more fieldwork to redress the inconsistencies between previously mapped intrusive units and the radiometric and magnetic data.
