Full description

A magnetotelluric survey of the Olary and Broken Hill domains, near the South Australian and New South Wales border, was conducted in 2007. Data were collected at 18 sites with a site spacing of 10 km, using five low frequency MT instruments. The data loggers were set to collect data at a rate of 10 Hz, which was averaged to 1 Hz before processing. Instruments were deployed at each site for approximately three days. Data were processed and inverted to produce three 2D resistivity profiles. Inversion profiles that cross the Mundi Mundi Fault show an order of magnitude increase in crustal resistivity moving from the Olary to Broken Hill domain, suggesting the Mundi Mundi Fault represents the boundary between the Olary and Broken Hill domains.
