STRATIGRAPHIC REVISION OF THE MIOCENE TREALLA LIMESTONE (CAPE RANGE, WESTERN AUSTRALIA): IMPLICATIONS FOR AUSTRALASIAN FORAMINIFERAL BIOSTRATIGRAPHY

摘要

Outcrops of Miocene coral-rich limestones mapped as Trealla Limestone are widespread along the coast of north-west Western Australia. Despite their central importance in Australian Miocene stratigraphy, the age of these outcrops is poorly constrained as they were only dated in their type area, and as the age assignation was based only on off-centred sections of sparse planktonic foraminifera and a broad correlation based on larger benthic foraminiferal species.
