| Lithology description: "Light grey, thin bedded limestones" The formation is composed predominantly of light 12 grey, slightly dolomitic, micritic mudstones with interbeds of bioclastic packstone. Members 1 and 3 can be discriminated from Member 2 by their irregular bedding and rubbly- or nodular-weathering appearance. Member 1 is much more fossiliferous than the other two. | |
