Victorian Aquifer Framework - Lower Tertiary Basalts (b)- Thickness of Basalt

Thickness of Lower Tertiary Basaltsandnbsp; - LTBb - 112 -andnbsp;\r\n\r\nThe thickness of the and#39;phase 2and#39; basalts aquifer is determined by subtracting the depth of the base layer from the depth of the surface layer. As the geological components vary within and between aquifers, this is not an indication of volume or yield.andnbsp;\r\n\r\nThe Victorian Aquifer Framework (VAF) was developedandnbsp;by the Department of Sustainability and Environmentandnbsp;(DSE, nowandnbsp;DELWP) to provide a consistent approach to defining, naming and numbering the commonly accepted aquifers, aquitards and geological layers that make up Victoriaand#39;s groundwater systems. It is intended to assist in the sustainable management of groundwater resources in Victoria and provide the framework for mapping aquifers and aquitards across the State.\r\n\r\nThe 3D numeric surfaces (grids) of each layer have been styled and converted to GeoTIFF by the VVG project to optimise them for display and querying on the web.andnbsp;
