Abstract
THE Precambrian crystalline basement of northwest Scotland, the Lewisian, has been described by various authors1,2. Sutton and Watson3 defined two distinct metamorphic episodes in the Lewisian, the Scourian and the later Laxfordian, both of which occurred before the deposition of the Precambrian Torridonian Sandstone. The absolute age of these Precambrian rocks has not been determined, however.
