“The area of the survey covers a space of about 400 km by 400km, and we generate models of the Earth that extend to 400 km. Thus, our outputs are a cube of data!

Our top view shows the topography of the surface with the Flinders Ranges and the Barrier Ranges in lighter green colours, and the deeper parts of the basin are almost at sea level in blue. The black line shows the geological extent of the Curnamona Province which is the old piece of geological crust that has existed for more than 1 billion years.

Below the topography and down to 400 km, we show electrical resistivity; red colours show zones that conduct electricity well, blue regions are insulators. Like a dice, we can spin the cube to show various faces, slice the cube along faces, and can restrict views to just smaller ranges of values.”
