Tasmania Geology
Tasmania rock units, with the faults and contacts that control gold.
What it shows
Surface geology for Tasmania at 1:250,000, from Mineral Resources Tasmania, painted in the survey's own per-unit colours. The coloured areas are rock units (lithology). The lines are mapped faults and contacts. It is the statewide map, so it covers the whole island. Read geology first, as it shows why gold sits where it does: faults are where fluids moved and gold dropped, and contacts between rock types often mark the same boundaries. Tap a unit for its name and age, or a line for the structure type. Use it to follow a favourable rock or a fault in the direction it runs, 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.
