Where to find Peanut Wood Jasper
Western Australia
The primary and most well-known source of Peanut Wood Jasper is the Kennedy Range in Western Australia, particularly from the Cretaceous Birdrong Shale formation. It is often found as river-worn pebbles and cobbles.
Collecting tips
- Look for distinctive patterns. The most defining characteristic is the 'peanut' or oval-shaped markings against a darker background. These are unmistakable once recognized.
- Check for hardness. As a form of jasper (quartz), it will be hard (Mohs 6.5-7) and will scratch glass.
- Examine for wood grain. Even though it's silicified, faint remnants of the original wood grain might be visible in the darker matrix, especially on unpolished surfaces.
- Consider the geological context. It is found in ancient marine sedimentary environments, often associated with shale or sandstone formations that once contained driftwood.
