The Rabbitkettle Formation is a geologic formation in the Yukon, comprising thin bedded silty and occasionally siliciclastic limestones deposited in deep (below storm wave base) waters.{{cite journal |last1=Pratt |first1=Brian R. |title=An Ibexian (Early Ordovician) trilobite faunule from the type section of the Rabbitkettle Formation (southern Mackenzie Mountains, Northwest Territories) |journal=Canadian Journal of Earth Sciences |date=October 1988 |volume=25 |issue=10 |pages=1595–1607 |doi=10.1139/e88-152}}{{cite web|url=http://paleoarchive.com/literature/Bruton1984-07-Barnes-EustaticEventsCanada.pdf |title=Early Ordavieian eustatic events in Canada |website=paleoarchive.com|access-date=21 May 2023}} It preserves fossils dating back to the Ordovician period.

According to it:

• Starts in the Late Cambrian; ends in late Tremadoc
• reaches 750m in thickness
• transitional slope facies
• Alternation of black calcareous mudstones and grey, burrowed wackestones
