Cargelligo 100K maps
and Ungarie1:100 000 geology maps
First edition Cargelligo, Hillston, Merriwagga, Tullibigeal, Rankins Springs and Ungarie 1:100 000 geology maps are now available. Essentially 'fact maps' over part of the western Lachlan Orogen and Murray Basin, they define outcropping areas of Palaeozoic rock, infer subsurface structure and detail components of the regolith.
The Hillston and Merriwagga maps overlap the eastern edge of the Murray Basin and are dominated by Cainozoic alluvial and aeolian sediments and ridges of Late Devonian sedimentary rock.
Outcrop on the Rankins Springs map includes spectacularly folded Late Devonian sedimentary rocks, Siluro-Devonian silicic volcanic rocks and tin-tungsten-bearing Silurian granite.
The Cargelligo map is dominated by prominent ranges of Siluro-Devonian submarine to subaerial silicic volcanic rocks of the Rast Trough, Devonian shelf sedimentary rocks and mineralised Ordovician metasedimentary rocks.
The Tullibigeal and Ungarie maps are notable for containing Silurian granites hosting tin and tungsten, and deformed gold-bearing Ordovician metasedimentary sequences.
The new products complement the previously published Cargelligo1:250 000 geology map and Cargelligo Explanatory Notes.
