Fintry Hills Lava Member is part of the [[Clyde Plateau Volcanic Formation]].<br />
=== Name ===<br />
Previously named the Fintry Hills Group (see Francis et al., 1970)<ref name="Francis70">Francis, E H, Forsyth, I H, Read, W A, and Armstrong, M. 1970. The geology of the Stirling district. ''Memoir of the Geological Survey of Great Britain'', Sheet 39 (Scotland)</ref>.<br />
<br />
=== Lithology ===<br />
The Fintry Hills Lava Member consists predominantly of plagioclase-macrophyric basalt lavas (‘Markle’ type) with a fairly high proportion of microporphyritic basalts and rare basaltic-trachyandesite (mugearite). Tuff occurs locally at (NS 6409 8794).<br />
<br />
=== Stratotype ===<br />
The type area is in the highest parts of the Fintry Hills, north-east of Glasgow (NS 6369 8867 to NS 6321 8911) (Francis et al., 1970)<ref name="Francis70"></ref>.<br />
<br />
=== Lower and upper boundaries ===<br />
The basal basalt of the member lies apparently conformably or disconformably on trachybasalt of the [[Shelloch Burn Lava Member]]. The upper boundary is eroded but not exposed.<br />
<br />
=== Thickness ===<br />
More than 122 m. The top of the member is eroded.<br />
<br />
=== Distribution and regional correlation ===<br />
The member is restricted to the Fintry–Touch Block (Francis et al., 1970)<ref name="Francis70"></ref> and specifically to the Fintry Hills, north-east of Glasgow. These rocks crop out across the hilltops of the central part of the Fintry Hills (NS 6369 8867 to NS 6321 8911).<br />
<br />
=== Age ===<br />
Mid Visean (Arundian to Asbian).<br />
