Brief description

Airborne electromagnetic (AEM) data measure variations in the conductivity of the ground by transmitting an electromagnetic signal from a system attached to a plane or helicopter. Depending on the AEM system used and the sub-surface conditions, AEM techniques can detect variations in the conductivity of the ground to a depth of several hundred metres. The responses recorded are commonly caused by the presence of electrically conductive materials such as salt or saline water, graphite, clays and sulphide minerals. Value: Data used for interpreting the geologic structure of the subsurface. This work can be used for the assessment of resource potential. Scope: Systematic coverage of large portions of the Australian continent.
