Abstract

In the southern Inner Hebrides Malin Sea region between Scotland and Ireland, a sequence of metasedimentary rocks, known as the Colonsay Group, is in contact with an older deformed igneous complex regarded as basement and termed the Rhinns Complex (Fig. 19). Early workers correlated the basement with the late Arclhaean Lewisian Complex of NW Scotland and the Outer Hebrides (Wilkinson 1907; Cunningham-Craig et al. 1911; Bowes & Hopgood 1975; Macintyre et al. 1975). However, more recent work has shown that the basement rocks are quite different from Lewisian rocks and comprise a deformed, Palaeoproterozoic (1.9 1.7 Ga) alkaline igneous complex (Muir 1990; Muir et al. 1992)
