Where is Sodalite Found in Australia?

Sodalite is a rich royal blue mineral that is prized for its color and ornamental uses. While it can be found in many parts of the world, some of the highest quality sodalite specimens come from Australia. Here is an overview of where sodalite deposits can be located across the Australian continent.

Northern Territory

Some of the most significant sodalite deposits in Australia are found in the Northern Territory. The Borroloola region hosts rich sodalite veins cutting through nepheline syenite rocks. Major mining activities in the area excavated large quantities of gem-quality sodalite crystals in the 1980s and 1990s. While commercial mining has declined, the area remains a top source for Australian sodalite mineral specimens for collectors.

Smaller sodalite deposits have also been found farther south near the Umbrawarra Gorge in the Northern Territory. These locations produce sodalite ranging from transparent to translucent with vivid blue hues.

South Australia

The Mount Painter area in the Flinders Ranges of South Australia holds sodalite deposits near the Arkaroola Wilderness Sanctuary. This sodalite often forms masses and veins within granite pegmatites. Sodalite from this area tends to be more opaque and richly colored than other Australian deposits. Some gemmy material can also be found within these sodalite-bearing pegmatites.

Additional minor sodalite occurrences have been noted across southern and western regions of South Australia. These are generally small veins and have not been commercially developed.


A recently discovered sodalite deposit was identified at Blue Mountain near Mount Isa in northwest Queensland. This sodalite is found as veins and masses cutting through nepheline syenite. The material ranges from transparent to translucent with intense blue coloring. The Blue Mountain sodalite find shows promising potential as a new productive deposit of fine Australian sodalite.

Isolated occurrences of sodalite have also been found scattered across eastern and northeastern Queensland. These are typically small deposits that have not been exploited commercially. More extensive exploration across Queensland may uncover additional significant sodalite locations.

Western Australia

The Landor area near Mount Magnet in Western Australia hosts sodalite as a accessory mineral found in some pegmatite bodies. Large crystals are rare, but small granular masses showing the characteristic sodalite blue color can be found. While not a major source, Landor provides some contribution to Australia’s overall sodalite deposits.

Additional minor sodalite pegmatites have been identified across the Pilbara and Kimberley regions of Western Australia as well. However, no major commercial mining activities have been established for sodalite in these locations.

In summary, the Northern Territory currently stands as Australia’s premier source for fine sodalite mineral specimens, with additional deposits across South Australia and Queensland continuing to produce material for collectors. Ongoing exploration across the continent may reveal new sources of this prized royal blue mineral. For now, determined rockhounds have their best chances finding fine Australian sodalite in the remote Northern Territory.
