The 2700 Road zeolite occurrence is within volcanic rocks of Eocene age which crop out to the west of the Fraser fault and which are correlative with similar rocks of the Kamloops Group to the east of the fault. These volcanics comprise an overlap assemblage within the Intermontane belt.

Rhyolitic tephra of the 2700 Road showing is northwest trending and is exposed over an area about 50 metres by 500 metres. The showing consists of bentonite-rich ash layers grading upwards into well bedded crystal and lapilli tuff. X-ray diffraction analysis of the tuff has identified clinoptilolite-heulandite group zeolites.
