History of Helidon Sandstone
Sandstone is typically a sedimentary rock, where through the movement of water sand was deposited and compacted though pressure of overlying deposits and cemented by the precipitation of minerals within the pore spaces between sand grains. Sandstone is compiled mainly of quarts grains cemented together by calcite, clays and silica, formed in a low pressure and low temperature environment.
Sandstone quarries are believed to have started emerging around the same time as the Ipswich to Toowoomba railway line which was built in 1866. Opening the area to an array of farming and mining opportunities, the first quarries in the area were government owned and run. The sandstone extracted from these first Helidon quarries were the building blocks to some of Brisbane’s most iconic buildings many now holding world heritage listings.
