The geologic history of the Australian continental mass is extremely prolonged and involved, continuing from the Archaean to the recent. In a gross pattern, continental Australia grew from west to east, with Archean rocks mostly in the west, Proterozoic rocks in the centre, and Phanerozoic rocks in the east.
The BMR was a geological survey with the main objective was the systematic geological and geophysical mapping of the continent as the basis for informed mineral exploration. [6] Geoscience Australia's activities have expanded and today it has responsibility for meeting the Australian Government's geoscience requirements.
The colour is pale grey with mineral white feldspar, milky grey quartz, black biotite, and with hornblende rich xenoliths. Minor minerals are apatite and zircon. The surrounding Pittman formation rocks have been metamorphosed in a contact aureole to hornfels and spotted schist. A magnetic high matches the location indicating the presence of ...
Mining in Australia has long been a significant primary sector industry and contributor to the Australian economy by providing export income, royalty payments and employment. Historically, mining booms have also encouraged population growth via immigration to Australia , particularly the gold rushes of the 1850s.

Ore was carted to South Australia by camel trains, wagons and pack mules. A major secondary source of income became apparent, with extremely high silver grades recovered, including native silver, and other rare silver minerals present in abundance. Open-pit mining of silver oxide ores was the norm from 1885 to 1898, with local smelting. From ...
The natural history of Australia has been shaped by the geological evolution of the Australian continent from Gondwana and the changes in global climate over geological time. The building of the Australian continent and its association with other land masses, as well as climate changes over geological time, have created the unique flora and ...
The Prominent Hill Mine is a major copper, silver, and gold mine in north west South Australia, 130 km south-east of Coober Pedy, which was developed by Oxiana Limited, later to become OZ Minerals, and now owned by BHP. The deposit is an iron oxide copper gold style mineralisation.
