40. Baxter - Middle Miocene Sediments

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 – 400696. Watson Creek, two kilometres east-south-east of Baxter railway station.
Access:Henderson Road.
Ownership:Private land.
Geomorphology:Chapman (1921) reported a ‘sandy ironstone band …..crossing Watsons Creek….half a mile west of the Baxter Railway station’. The bed contained fossil casts and was subsequently described by Keble (1950) as a sandy claystone, and positioned by him as '1.3 miles east-south-east of Baxter railway station’. The outcrop has not been located in the field during this survey.
Significance:Regional. The stratigraphical position of these beds has not been exactly determined, but they are regarded by Jenkin (1974) as the probable equivalents of the Balcome Clay. The site represents the only documented outcrop of this formation in the study area.
Management:Class 2. Extensive filling or construction activities that obscure the creek channel should not be permitted.
