Mount Cedric is a complex vent, 400 metres long by 200 metres wide, intruded into sandstone of the Permian Hardman Formation. There are two major intrusive centres, a satellite vent on the southern margins, and another 200 metres to the west.
The pyroclastic deposit is well bedded clast supported lapilli tuffs of fine grained vesicular olivine-leucite lamproite, up to 10 mms across, and 10% shale and siltstone wall rock clasts.
Centre One has an outer zone of xenolith bearing fine grained olivine-leucite lamproite, and inner similar but with no xenoliths. It represents a series of pulses from the same magma.
Centre Two has intruded into Centre One. It consists of a partial cone sheet of columnar jointed xenolith bearing olivine-leucite lamproite, surrounded by an irregular mass of olivine-diopside-potassic richterite-leucite lamproite, and a small centre plug of diopside-olivine-leucite lamproite. The core of Centre Two has a distinctive olivine rich rock, containing abundant corroded olivine macrocrysts up to 4 mms across.
