| Lithological Description: |
The Neilston Lava Member consists of alkali basalts with minor basanite in the lower part and trachybasalt in the upper. |
| Definition of Lower Boundary: |
The base is apparently conformable on the Moyne Moor Lava Member, which consists predominantly of trachybasalt, but it might locally be unconformable. |
| Definition of Upper Boundary: |
The Member is overlain by the trachytic Harelaw Lava Member. The contact is unconformable. |
| Thickness: |
