Stirling Range, Australia
The Stirling Range is a 60-km long range of hills in southwestern Australia, about 330 km SE of Perth. It is built up of a ca 1.6 km thick Paleoproterozoic sequence of siliciclastic sediments, the Stirling Range Formation. The sediments, mostly sandstones and shales, were deposited between 1.8 and 2 Ga ago along an ocean-facing shoreline influenced by storms, long-shore currents, and tidal currents. The rocks were subjected to low-grade metamorphism about 1.2 Ga ago. The Stirling Range Formation houses a fossil biota of disk-shaped and trace-making organisms, the Stirling Range Biota.
