The predominent areas of both the Chapel Hill and Jupiter Creek diggings and now set aside as fossicking areas, for futher details contact PIRSA.
The Old Echunga Diggings comprise a number of locations on a 12km x 5km area. The gold was found and recovered from the quartz reefs in the Adelaide Geosyncline sediments (Aldgate Sandstone, Woolshed Flat shale/Burra group) and from alluvial deposits in the Tertiary and Quaternary formations.
Some of the names listed in the Chapel Hill Diggings include;

|Cambrian-Ordovician443.8 - 541 Ma||Cambrian-Ordovician intrusive and metamorphic terranes|
Intrusive and metamorphic terranes
Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
|Cryogenian635 - 720 Ma||Neoproterozoic sedimentary rocks |
Predominantly sedimentary rocks; includes sedimentary rocks of low metamorphic grade and diapiric breccias
|Cryogenian635 - 720 Ma||Emeroo Subgroup|
sedimentary siliciclastic; synthesis of multiple published descriptions
