Eaglesham Lava Member (EMLA), Dunlop-Eaglesham Block, Carboniferous, Midland Valley of Scotland[edit]

The Eaglesham Lava Member is part of the Clyde Plateau Volcanic Formation.

Name[edit]

Previously named the Eaglesham lavas. See MacPherson and Phillips (1997)[1]; Phillips and MacPherson (1996)[2]; MacPherson et al. (2000)[3].

Lithology[edit]

The Eaglesham Lava Member is dominated by alkali basalt, but also includes basanite and feldspar-phyric trachybasalt. One trachytic flow is known.

Stratotype[edit]

The type area is the Dunlop–Eaglesham moors between Glasgow, Kilmarnock and Hamilton, in the eastern part of the area between Newton Mearns (NS 5750 5180) and Eaglesham (NS 5360 5570).

Lower and upper boundaries[edit]

The base is apparently conformable on the Moyne Moor Lava Member that consists predominantly of trachybasalt but may locally be unconformable.

The member is overlain by the Dumdruff Hill Lava Member. The contact is considered conformable.

Thickness[edit]

Up to 250 m.

Distribution and regional correlation[edit]

Dunlop–Eaglesham moors between Glasgow, Kilmarnock and Hamilton, in the eastern part of the area between Newton Mearns (NS 5750 5180) and Eaglesham (NS 5360 5570).

Age[edit]

Mid Visean (Arundian to Asbian).
