Small outcrops of leucitite lavas, estimated to cover 114 km² and with a volume probably not exceeding 3km³, are found within an area from central New South Wales into Victoria, extending for 640 km with a max width of 90km (Cundari 1989).
The lavas rest unconformably on a basement consisting of Paleozoic geosynclinal sediments and granites and at one locality, at least, overlie Cenozoic sediments.
