This is an annual map edition that shows australia's nickel resources - March 2009 edition.

Australia's global nickel endowment on geological regions. Global nickel is the aggregate of past production from a region plus current resources.

Map showing the location of publicly available Gravity data updated to May 2011

These charts show the seven elements of the Earth's magnetic field for the Australian region, as calculated from the year 2000 revision of the Australian Geomagnetic Reference field model at epoch 2000.0(AGRF00)

Sheet 1 shows copper resources of geological regions. Sheet 2 shows styles and ages of copper deposits.

The Australia Epoch 1995.0 geomagnetic field chart maps the main geomagnetic field and its secular variation in the Australian region between 1995 and 2000 . The chart is derived from the Australian Geomagnetic Reference Field model (AGRF) of the same epoch. From 1990 to 2005 the AGRF has been updated at five yearly epochs. A main field model is produced for each five yearly epoch, along with a prospective secular variation model to extend the life of the model. The AGRF model represents the Earth's main magnetic field originating from the core and the broad scale crustal field. The AGRF does not model short term variations of the magnetic field with time, such as those caused by solar activity or ionspheric currents. The AGRF is derived from vector magnetic data from ground level, aircraft and satellite surveys as well as the network of geomagnetic observatories and repeat stations run by Geoscience Australia and neighbouring countries. (This chart is now superseded.)
