39. Langwarrin - Silurian Outcrop

This information has been developed from one or more of these publications:

  • Sites of Geological and Geomorphological Significance in the Westernport Bay Catchment (1984) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay (1988) by Neville Rosengren.
  • Sites of Environmental Significance in the Flood Plain of the Upper Yarra Valley Region (1983) by Neville Rosengren, Douglas Frood and Kim Lowe (as part of a study of Sites of Environmental Significance by the University of Melbourne for the then Upper Yarra Valley and Dandenong Ranges Authority).
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:Baxter – 390725. Railway cutting 500 metres south of Langwarrin railway station and road cutting on McLelland Drive (also known as Boundary Road) south of Robinsons Road.
Image: Sites of Significance Westernport Bay
Folded and faulted Silurian sediments along McLelland Drive (Boundary Road), Langwarrin, Site 39.
Access:McLelland Drive.
Ownership:Crown Land.
Geology/Geomorphology:Shales, mudstones, and thin sandstone beds are exposed in the cuttings. The beds in the railway cutting strike north-north-west and dip eastwards at 45°. Keble (1950) reported fossils including graptolites which indicated a lower Silurian age. The beds in the road cutting are gently folded and are faulted in the northern section of the exposure.
Significance:Regional. The outcrop lies close to the top structural axis of the Mornington Peninsula and is of interest to demonstrate the position of the Silurian strata in relation to that axis.
Management:Class 2. Activities that caused the outcrop to be obscured should not be permitted.
