K9 - Silcrete and Newer Volcanics, Jacksons Creek.

Site Description
On the southern valley slopes of the Maribyrnong River, a small disused quarry exposes a section of Silurian sediments underlying Older Volcanics basalt. Above the Older Volcanics are sandy sediments, indurated to silcrete, and overlying these are flows of Newer Volcanics basalt.

Significance
Regional The site is an example of a geological contact and a substantial outcrop of sub-basaltic silcrete. It is an uncommon example of both Older and Newer Volcanics exposed in the one section.

Management
The slope should be left in existing condition to allow display of the geological features described.
