|Location||Keilor - 035290. Shires of Melton and Bulla. Valley of Jacksons Creek 9 km northwest of Keilor.|
K3 - Silurian sediments (S) underlying Newer Volcanics (V), Jacksons Creek Valley, Organ Pipes National Park.
|Access||Organ Pipes Road off Calder Highway.|
|Ownership||Crown land (National Park)|
|Site Description||(A brief statement only is given as there is ample material available from the managing authority of the site - the National Parks Service.)|
|The valley of Jacksons Creek exposes steeply dipping fossiliferous Silurian sedimentary rocks overlain by flows of Newer Volcanics basalt. Structural features such as bedding and jointing are clearly displayed at several localities as is the contact between the formations. Erosional and depositional features of the valley (both relict and active) are also evident.|
|Significance||State. The site is an excellent example of structure of the Silurian sediments and the Newer Volcanics and of the burial of a former landscape lave flows. It provides a clear display of the processes of valley incision by the major tributary of the Maribyrnong River.|
Class 1. Continued application of current management principles by the National Parks Service is adequate to maintain the qualities of the site.
