Breccia, angular clasts of Carboniferous limestone (dolostone) set in a red-brown, very fine-grained, clayey sandstone matrix. |
| Definition of Lower Boundary: |
The lower boundary is where breccia unconformably overlies dolostone of the Carboniferous Limestone; it may also conformably overlie red mudstone/siltstones/sandstones of the Gunthorpe Member, but this relationship has not been observed. |
| Definition of Upper Boundary: |
The upper boundary is where typically red-green mudstones, siltstones or sandstones of the Gunthorpe Member overlie breccia. |
