Lower Flow Moss Lava Member (LFMLA), Dunlop-Eaglesham Block, Carboniferous, Midland Valley of Scotland[edit]

The Lower Flow Moss Lava Member is part of the Clyde Plateau Volcanic Formation.

Name[edit]

Previously known as the Flow Moss lavas (lower). See MacPherson and Phillips (1997)[1]; Phillips and MacPherson (1996)[2]; MacPherson et al. (2000)[3].

Lithology[edit]

The Lower Flow Moss Lava Member consists of alkali basalt and subordinate basanite.

Stratotype[edit]

The type area is the Dunlop–Eaglesham moors between Glasgow, Kilmarnock and Hamilton, limited to the southern part of the area between Stewarton (NS 4200 4500) in the west and Craufurdland Water (NS 510 448) in the east.

Lower and upper boundaries[edit]

The nature of the base is unknown but may be unconformable on the Inverclyde Group or older strata.

The member is overlain by and interbedded with the Moyne Moor Lava Member in the western part of the area of occurrence. Elsewhere, where locally known, a thick bole is developed on the uppermost flow at (NS 510 448) and the Upper Flow Moss Lava Member rests on this.

Thickness[edit]

Not stated.

Distribution and regional correlation[edit]

Dunlop–Eaglesham moors between Glasgow, Kilmarnock and Hamilton, limited to the south of the area between Stewarton (NS 4200 4500) in the west and Craufurdland Water (NS 510 448) in the east.

Age[edit]

Mid Visean (Arundian to Asbian).
