Brokenhillite is a rare mineral that is only found in the far-western regions of New South Wales in Broken Hill, Australia.

The tetrahedral silicates are inosilicates with octahedral dispersal around the islands bonding with oxygen ions.

Ultimately, brokenhillite has broken up disordered stacking due to the inosilicate structure.

Brokenhillite is found in Broken Hill, New South Wales, Australia in a mine with a wide variety of other minerals present.

The hexagonal shape and brown color make it distinguishable especially when a phenomenon called pleochroism occurs when light shines through and it becomes translucent white or yellow.
