Where to find Mookaite Jasper
Kennedy Range, Western Australia
The primary and virtually exclusive source of Mookaite Jasper is the Mooka Creek area within the Kennedy Range of Western Australia. It is found in weathered outcrops of the Windalia Radiolarite formation.
Collecting tips
- Geological Context. Mookaite is found in specific geological formations, particularly the Windalia Radiolarite. Understanding the stratigraphy of the Kennedy Range is crucial for professional prospecting.
- Weathered Outcrops. It is typically found in weathered exposures where the softer surrounding rock has eroded away, leaving the more resistant silicified Mookaite behind. Look for colorful fragments on the surface.
- Color and Pattern Recognition. Familiarize yourself with the characteristic color palette and swirled or banded patterns of Mookaite to distinguish it from other cherts or jaspers.
Quick Check
- Color:
- Red, yellow, cream, white, burgundy, brown, often swirled or banded.
- Luster:
- Dull to waxy.
- Streak:
- White (due to its silica composition).
