Summary

A recent bore-hole through the Shiant Isles picrite established the existence of 45 feet more of the picritic facies, and also the lower margin of the silt, at a point almost vertically below the exposed 35 feet previously investigated. In the light of new field and laboratory information the pieritic facies is briefly re-examined and its origin discussed.
