K10 Keilor - Dry Creek/Maribyrnong River Confluence

This information has been developed from the publications:

Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren

Sites of Geological and Geomorphological Significance in the Shire of Otway (1984) by Neville Rosengren.

Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports. See the Earth Science Heritage section of the Geological Society of Australia website (external link) for details of geological heritage reports, and a bibliography.

Location Access Ownership	Keilor - 096246. Former City of Keilor. Valley of Dry Creek extending 300 m upstream from the confluence of the Maribyrnong River. Annandale Road. Private land and some Crown land	K10 - Unconformity between Silurian sediments (S) and Red Buff Sand, Maribyrnong River/Dry Creek, Keilor.
Site Description	Geological sections exposed along the stream banks and in quarries, show a sequence (from bottom up) through Silurian sediments, cemented sub-basaltic sediments, Older Volcanics, Tertiary sediments and Newer Volcanics. The valleys of the streams have been partly infilled with alluvial terraces and these are particularly well developed in the Keilor area.
	The terraces have yielded important archaeological material and have been investigated and mapped in considerable detail. A number of radiocarbon dates of materials contained in the terraces has been published. The archaeological significance of these sites has not been evaluated in this report.
Significance:	Regional. The site provides an excellent display of the geological materials of the Maribyrnong River valley. There is a particularly good exposure of the unconformity at the top of Silurian sediments.
Management:	Class 2. The geological sections that are stable (not in danger of collapse or slumping) should be retained. Advice on conservation of significant archaeological features at the site should be obtained.
