Granite is a natural stone that has been used by humans for more than 300 million years, from everyday tools in the Neolithic era to modern-day buildings and monuments. It is a popular material due to its strength, durability, and resistance to weather conditions. In Australia, granite can be found in various forms, such as Ruby Red, Paradise Blue, and Adelaide Black, and is mainly produced and exported from South Australia. The state's granite production leads the country, with quarries located on the northern Eyre Peninsula and the eastern Mount Lofty Ranges.

South Australia is Australia's largest producer of granite
Today, South Australia exports much of its granite production as raw blocks weighing up to 30 tons. The state is home to Australia's largest granite quarries, which are located at Black Hill near Mannum. The quarries produce an igneous rock of gabbroic composition, which is marketed as Austral Black Granite or Imperial Black Granite.
The granite quarries on the Eyre Peninsula are located in plutons of anorogenic Hiltaba Suite granite of Mesoproterozoic age. These granites are characterised by their red or pink colour, which is caused by the presence of abundant minute iron oxide inclusions within the plagioclase and K-feldspar. The best-known granite from this region is Calca Red Granite, which has been quarried near Streaky Bay since 1975.
In addition to the Eyre Peninsula quarries, South Australia also has granite quarries in the eastern Mount Lofty Ranges and the South-East of the state. The state's granite production has been enhanced by advancements in granite processing technology, particularly in diamond sawing and computer control systems. These advancements have made granite a more affordable material for domestic applications such as tiles and benchtops.

Granite quarries in Australia market stone as Imperial Black Granite or Austral Black Granite
South Australia is Australia's largest producer of granite, with quarries on the northern Eyre Peninsula and in the eastern Mount Lofty Ranges. The state's granite production has increased dramatically over the past 60 years, with modern multi-storey buildings using thin external granite panels as cladding over steel load-bearing frames. This shift in building technology has made granite a more affordable and popular choice for domestic applications such as tiles and benchtops.
Australia's largest granite quarries are found at Black Hill near Mannum, where the stone mined is technically an igneous rock of gabbroic composition. Despite not being true granite, the rock is marketed as Imperial Black Granite or Austral Black Granite, depending on the visibility of igneous layering in the final product. The Black Hill quarry is primarily operated by Granites of Australia, which owns three additional granite quarries in New South Wales: Riverina, Mudgee, and Steel Grey granites.
The Eyre Peninsula is known for its distinctive red and pink granites, caused by abundant minute iron oxide inclusions within the plagioclase and K-feldspar. The most well-known variety is Calca Red granite, which has been quarried near Streaky Bay since 1975. Other varieties produced in the region include Desert Lilac, Desert Ruby, and Desert Rose.
In addition to South Australia, granite can be found in various other parts of the country, including Western Australia, eastern Australia, and Tasmania. The granite-related mineral system is present throughout much of Australia and is associated with a range of critical commodities and deposits.

Granite is used for outdoor applications like paving, landscaping and pool coping
Granite is a popular choice for outdoor applications such as paving, landscaping, and pool coping. Its natural beauty, durability, and strength make it an excellent material for these purposes. With its ability to withstand temperature fluctuations and resist wear and tear, granite is a long-lasting option for outdoor areas.
Granite pavers can be used to create stunning patios, walkways, courtyards, and pool areas. They come in various colours, from pink to black, allowing for creative design options. For example, using a contrasting colour to edge a walkway or adding a ""wow"" factor around a swimming pool. Granite's natural stone characteristics make it ideal for pool coping, as it can withstand extreme weather conditions, including heat, rain, and snow.
In addition to its aesthetic and functional benefits, granite is also a "green" material. Unlike concrete pavers, which contribute to landfill waste, granite pavers can be recycled or reused. This makes it a more sustainable option for outdoor applications.
South Australia, particularly the quarries on the northern Eyre Peninsula, is a significant source of granite in Australia. The state has a long tradition of stone production and usage due to its deficiency in timber. The distinctive red or pink colour of the granite from this region is caused by the presence of iron oxide inclusions within the plagioclase and K-feldspar.
Overall, granite is a versatile and durable material that adds value and elegance to outdoor spaces. Its natural beauty and strength make it a popular choice for landscaping, paving, and pool coping applications. With proper sealing and care, granite can withstand the test of time and provide a timeless look to any outdoor area.
