Location:

993480. Four kilometres west of Buchan.

Abstract:

Exposures of Snowy River Volcanics and Yellow Waterholes Fault.

Access:

Davidsons Lane.

Ownership:

Crown land and private land.

Geology:

Yellow Waterholes Creek has excavated a meandering channel along the Yellow Waterholes Fault. This fault divides the Snowy River Volcanics into the older Timbarra Formation, and the younger Gelantipy Formation. A thin crush zone associated with this fault is exposed in Davidson Lane (A). Fine grained white sandstones, interbedded with tuffs are exposed to the east of the fault and at the junction of Yellow Waterholes Creek and Davidson Lane. Pink and grey rhyodacites are exposed in the creek channel. Further downstream, poorly exposed rhyolites show flow banding (C), and an andesite flow outcrops (D). The inclusion of these latter rocks in the Gelantipy Formation has been questioned by several writers as the almost total absence of ferromagnesium minerals has been regarded elsewhere as a diagnostic characteristic of the Gelantipy Formation.

Significance:

Local. Although exposures are poor, outcrops in the area display the major rock types comprising the Gelantipy Rhyodacite.

Management:

Access to the site should be maintained and formalized with the owners of private land in the area.
