Bulletin 57: Early Cretaceous sediments reveal a story of prolonged cold climate, glaciations, oscillating sea level and tectonic changes by Dr Neville Alley and Stephen Hore (2022).

South Australia has the only physical evidence of an Early Cretaceous glacial period in marine and terrestrial outcrops in the northern Flinders Ranges.

Bulletin 57 is the culmination of detailed geological research over many years, supported by the Geological Survey of South Australia (GSSA). It highlights evidence of an Ice Age during the Early Cretaceous, a time when we previously thought the planet was hot and humid.

This work contributes to an evolved understanding of our planet's geology through:
surveys of rock outcrops
new and time-proven analytical processes
literature research
rigorous testing of existing theories.

Which revealed:
a story of a prolonged cold climate
potential pathways for future critical elements to accumulate in the sediments.
