New South Wales Geology
New South Wales rock units, with the faults and contacts that control gold.
What it shows
Seamless surface geology for New South Wales at 1:250,000, from the Geological Survey of NSW, in the survey's own per-unit colours. The coloured areas are rock units (lithology). The lines are mapped faults, the contacts between units, and thin marker beds and dykes. 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, lithology 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.
