This layer shows a depth slice from a 3D resistivity model of the crust derived from an inversion of the AusLAMP NSW long period MT data.

This vector contains the flight lines from the MinEx Collaborative Research Centre (CRC) Cobar Airborne Electromagnetic (AEM) survey. This survey was a collaboration between the Geological Survey of NSW and Geoscience Australia

Depth to the Mohorovičić discontinuity (Moho) interpreted and modelled by Geognostics with support from government and industry. The Moho surface is the boundary between the Earth's crust and the upper mantle. The depth to moho is a representation of the thickness of the Earth's Crust. This moho surface is derived from seismic, gravity and other geophysical datasets.

The Geochemistry (Whole Rock) data set contains information about the chemistry of rocks sampled in New South Wales and held by the Geological Survey of NSW (GSNSW). The data has been captured from analyses conducted by the GSNSW and from other work including academic research & collaborative projects, mineral exploration reports and geoscientific publications. The database contains geochemical analyses on nearly 27,000 rock samples which have been collected from field work and drilling activities which date back to the nineteenth century. There are also a small number of assay & hydro-geochemical results. It is an important dataset as the whole rock analysis of rocks for major and trace elements allows classification of the lithology of a rock and provides insight into the conditions in which the rocks formed as well as their economic potential.

Total heat flow at surface model (2023) created by Geognostics with support from government and industry. This model is the sum of all heat-flow contributions (mantle heat flow, lower crustal heat flow, upper crustal radiogenic heat flow and sedimentary heat flow). This is modelled using a bottom up approach starting from the mantle and calculating upwards: Qtotal = Qmantle + Qlowercrust + Qupper crust + QSediments Basement composition and terranes dominate total heat flow, especially where sediment cover is thin. Where sediments are thick then these sediments mute the basement signatures. The total heat flow patterns closely follow upper crustal radiogenic heat production.

Depth to the Lithosphere–Asthenosphere Boundary (LAB) modelled by Geognostics with support from government, academia and industry. The LAB surface is the base of the ridgid lithosphere and the top of the ductile asthenosphere. In geothermal terms it marks a thermal and mechanical tranisition in the Earth at a temperature of 1330 °C. This surface is modelled using themal modelling (mantle heat flow, crustal heat production, thermal conductivity, Moho depth and lithospheric structure) seismic tomography, magnetotellurics, global and regional geodynamic models and tectonic context.
