Pine Creek - Kombolgie VTEM AEM Survey, NT, 2009 Final Data (P1195)

Brief description

During 2008 and 2009, and under the Australian Government's Onshore Energy Security Initiative, Geoscience Australia acquired airborne electromagnetic (AEM) data over the Pine Creek Orogen of the Northern Territory. The survey area was split into three areas for acquisition. VTEM data was acquired in the Kombolgie area east of Kakadu National Park (this data set) between August and November 2008. TEMPEST data was acquired west of Kakadu National Park with the area split in two to facilitate the use of two aircraft: the Woolner Granite area in the north was acquired between October and December 2008; and the Rum Jungle area adjoining to the south, was acquired between October 2008 and May 2009. The main purpose of the surveys was to provide additional geophysical / geological context for unconformity style uranium mineral systems and thereby promote related exploration. The survey data will also provide information on depth to Proterozoic/Archean basement, which is of general interest to explorers, and will be used as an input into ground water studies in the region. The data are available in two parts: - Part A, which consists of Grids (4MB) + Multiplots (85MB) + Report (8MB) + Waveform (43 MB) is available as a free download - Part B, which consists of Part A [Grids (4MB) + Multiplots (85MB) + Report (8MB) + Waveform (43 MB)] plus Line data. Together they are too large for web downloading and therefore Part B is only available, on DVD.
