The Sleat and Torridon Groups

  • Chapter

Abstract

These two groups, as explained in the Introduction to Chapter 8, form a conformable sequence roughly 200 Ma younger than the Stoer Group. They seem to have originated during a later episode of extension across the same rift system which had earlier received the Stoer Group. The petrography and geochemistry of the younger sediments show, however, that the source area was quite different and the climate much wetter. This difference in climate fits the palaeolatitudes deduced from palaemagnetism—15° for the Stoer Group but 30–50° for the Torridon Group (Smith et al, 1983).
