Researchers discuss the evidence on the Trendall Locality ridge

Strelley Pool Chert: How did it form?

The Strelley Pool Chert in the Trendall area marks a quiet era of some millions of years between two volcanic episodes. The chert - a fine-grained sedimentary rock - appears to have been laid down in a normal marine environment - a lagoon or shallow sea with a microbial reef system.
