| Lithological Description: |
[Obsolete: use FMLA]
The Upper Flow Moss Lava Member consists of alkali basalts and subordinate basanites and ankaramites. |
| Definition of Lower Boundary: |
The base is apparently unconformable on the Harelaw Lava Member, which consists of trachytic lavas, and the volcaniclastic rocks of the Gowk Stane Member. A thick bole formed on the top flow of the Lower Flow Moss Member marks the contact with this underlying member. |
| Definition of Upper Boundary: |
The Member is overlain unconformably by the Kirkwood Formation (Strathclyde Group). |
| Thickness: |
Not known. |
| Geographical Limits: |
Dunlop-Eaglesham moors between Glasgow, Kilmarnock and Hamilton, widespread area between Neilston (NS 440 560) in the northwest and Darvel (NS 610 390) in the southeast. |
