Zebra Rock Siltstone

3D Model

Locality: Kununurra, Western Australia

Size: 12 x 7 x 3 cm

Description: This distinctive reddish-brown and white-banded sedimentary rock from the east Kimberley of Western Australia is called ‘zebra rock’ or ‘zebra stone’. The totally unique Zebra Rock has been placed at 600 million years in the upper Proterozoic era or Pre-Cambrian period. The only known deposits in the world have been discovered in the East Kimberly region.

The colour banding of zebra rock probably formed by the rhythmic precipitation of Hematite rich bands during the alteration of the rock by percolating fluids (fluids migrating through the rock).

On front is a oil painting made by Gary Johnston. He uses the smooth, sanded surface of the zebra-striped stone as a canvas for intricate depictions of native Kimberley birds.
