Magnetotelluric survey data acquired in association with the L189 Gawler-Curnamona-Arrowie Deep Crustal Seismic Survey over the Gawler Craton. This survey was a collaborative project with the University Of Adelaide and was funded through the Onshore Energy Security Program. The aim of the survey was to produce a two-dimensional image of electrical conductivity structure of the crust and upper mantle over the Gawler Craton. This information is complementary to the reflection seismic and gravity data acquired along the 08GA-G1 traverse.

Data quality

Lineage:

These data were acquired using Bartington 3-axis fluxgate sensors for long-period measurements and KMS LIC-120 land induction coil magnetometers for broadband measurements. Data were recorded on PR 6-24 Portable Earth Data recorders with GPS timing synchronisation. This equipment was supplied by AuScope.

Data was processed in Geoscience Australia to EDI files and modeled using WingLink software.

Positional accuracy:

Calculated location from GPS measurements acurate to less than 25 metres
