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.

Australia is the world's largest exporter of coal (35% of international trade), iron ore, lead, diamonds, rutile, zinc and zirconium, second largest of gold and uranium, and third largest of aluminium. [55] Japan was the major purchaser of Australian mineral exports in the mid-1990s. [31]
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 ...
Australia has been mining bauxite since the early 1960s and is a major economic player in worldwide bauxite mining. It is the largest producer of bauxite in the world, producing 31% of global production in 2016. Australia is also the largest exporter and second highest producer of alumina worldwide, with 17% of global production. [2]

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 ...
Southbound view of the M1 Pacific Motorway carved through sandstone at Berowra. Six kilometres of sandstone and shale lie under Sydney. In Sydney sandstone, the ripple marks from the ancient river that brought the grains of sand are distinctive and easily seen, telling geologists that the sand comes from rocks formed between 500 and 700 million years ago far to the south.
