Summary:Lower Carboniferous volcanic rocks from S Kintyre comprise transitional to mildly alkaline basalt, basaltic hawaiite, hawaiite, mugearite, benmoreite and trachyte. The compositional range can largely be explained by fractional crystallization of the observed phenocryst phases under polybaric conditions. Basaltic rocks from Kintyre and Arran in the Scottish Highlands province are isotopically distinct from their counterparts in the Midland Valley and Southern Uplands. This distinction is believed to be mantle- rather than crust-derived and implies long-term separation of the two mantle source regions. [R.A.H.]
