Micropalaeontological examination of limestone samples from the North Basin, Western Australia

This report describes the findings of a micropalaeontological examination of a small collection of limestones from Cape Range, Rough Range and Learmonth Aerodrome, Northwestern Australia. The collection is characteristic of the Tertiary deposits of the North West Basin. The majority of the limestones belong to the "f" stage (Middle Miocene) of the Netherlands East Indies "letter" classification but the shelly limestone from Rough Range, in the absence of zonal Miocene foraminifera is regarded as Lower Pliocene. A detailed palaeontological description of these samples is given in this report.
