The Upper Burdekin Basalt extents web service delivers province extents, detailed geology, spring locations and inferred regional groundwater contours for the formations of the Nulla and McBride Basalts. This work has been carried out as part of Geoscience Australia's Exploring for the Future program.

Hydrochemistry data for Australian groundwater, including field and laboratory measurements of chemical parameters (electrical conductivity (EC), potential of hydrogen (pH), redox potential, and dissolved oxygen), major and minor ions, trace elements, nutrients, pesticides, isotopes and organic chemicals. < <b>Value: </b>The chemical properties of groundwater are key parameters to understand groundwater systems and their functions. Groundwater chemistry information includes the ionic and isotopic composition of the water, representing the gases and solids that are dissolved in it. Hydrochemistry data is used to understand the source, flow, and interactions of groundwater samples with surface water and geological units, providing insight into aquifer characteristics. Hydrochemistry information is key to determining the quality of groundwater resources for societal, agricultural, industrial and environmental applications. Insights from hydrochemical analyses can be used to assess a groundwater resource, the impact of land use changes, irrigation and groundwater extraction on regional groundwater quality and quantity, assess prospective mineral exploration targets, and determine how groundwater interacts with surface water in streams and lakes. <b>Scope: </b>The database was inaugurated in 2016 with hydrochemical data collected over the Australian landmass by Geoscience Australia and its predecessors, and has expanded with regional and national data. It has been in the custodianship of the hydrochemists in Geoscience Australia's Minerals, Energy and Groundwater Division and its predecessors.

As part of the first phase of the Exploring for the Future (EFTF) program, depth estimates have been compiled across the North Australian Craton (NAC) in the Estimates of Geological and Geophysical Surfaces (EGGS) database. These depth estimates are ultimately intended to be used to build national-scale models of Australia’s geological cover sequences. EGGS contains depth estimate points of chronostratigraphic era boundaries derived from multiple geological and geophysical datasets. This includes points from the interpretation of airborne electromagnetic (AEM) and magnetotelluric (MT) datasets, as well as from magnetic modelling. Surface and solid geology maps, and formation tops data for groundwater, petroleum and mineral boreholes are linked with the Australian Stratigraphic Units Database (ASUD) to provide chronostratigraphic context for the depth estimates. Following on from work completed across the NAC, the structure of the EGGS database has been re-designed to better enable users to extract additional key information required to build 3D models, and abide by the FAIR (Findable, Accessible, Interoperable, Reusable) data principles. For example, EGGS now identifies points associated with a significant (era-scale) chronostratigraphic unconformity – such as where the Cenozoic overlies Paleozoic or older rocks – enabling better interpolation between points in gridded cover surfaces. We are extending our EGGS coverage to the south, along the Eastern Resources Corridor, including over the Cooper Basin. Newly added data from this area includes magnetic depth estimates from targeted magnetic inversion modelling, interpretation of the AusAEM Eastern Resources Corridor survey data, and compilation of well formation tops across South Australia, Victoria and New South Wales. These data will be used to generate a 3D depth to cover model over the Eastern Resources Corridor and contribute towards building a national-scale geological architecture model.
