Tasmania Magnetics (RTP-1VD)
Tasmania aeromagnetics, sharpened to show gold-controlling structures.
What it shows
An aeromagnetic image covering Tasmania, flown from aircraft, that maps the magnetism of the rocks below, including under soil and cover where nothing shows at the surface. This is the reduced-to-pole first vertical derivative of the national magnetic grid, a processed version that centres each anomaly over its source and sharpens the edges so faults, shear zones, intrusion margins and ironstone stand out as lines and patterns. These structures are where fluids moved and gold can sit. It is the national-resolution grid covering Tasmania; a finer state survey may be added later. It is a picture map, so it is look-only: tapping, recolouring and filtering are not available. Read it alongside geology to trace a fault or contact into new ground.
Putting this on your map
Taking a layer from the Library onto a stack, and tuning how it draws, is a short guided tour on your own map.
