| The unit comprises a thinly laminated heterolith of mudstone and fine-grained sandstone. |
| This facies consists of distinctly laminated mudstone, with a minor component of siltstone and very fine-grained sandstone. |
| The sedimentary lenses are composed of limestone, sandstone, siltstone, mudstone, shale, chert and well-bedded calci-turbidite. |
| The Elgee Siltstone consists of massive red siltstone, sandstone and green mudstone. |
| As coccolith content increases the calcareous mudstone passes transitionally to a coccolith limestone. |
| North of the Burd Gol zone there is a small area of interbedded marine mudstone and limestone which reportedly contain Carboniferous fossils. |
