AMONG the alkaline igneous rocks of Ayrshire are two groups of minor intrusions the age and genetic relations of which have aroused considerable interest in the past. The ‘kylites’ and ‘crinanites’ of Tyrrell1 were originally classified together and were thought to be differentiates of the same magma, but later work by the Geological Survey (MacGregor2) has suggested that this may not be the case.
