Historical information

This specimen was recovered from Adelong, NSW. The initial discovery of gold at Adelong by a Mr Williams took place in 1857. Much of the area is underlain by granitic rocks, while at Adelong itself a prominent norite intrusive body occurs. To the west of Adelong is a belt of intermediate to mafic igneous rocks and sediments which extends from Batlow in the south to at least as far north as the Snowy Mountains Highway. Around 26 tonnes of gold was found at the Adelong goldfield from its discovery in the 1850s until the last miners left in the 1940s.

Pyrite has the formula of FeS2 and forms as an isometric (cube) form. It is a common occurring material and is often mistaken for gold, now colloquially known as ‘fool’s gold’. Pyrite that has strongly crystallised is considered stable, but the mineral has the potential to oxidise and decay.

Significance

This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.

Physical description

Pyrite is iron sulphide (also known as “fool's gold”) which is commonly found in slates.
