Abstract
Synopsis: The geochemistry of the Lewisian and Moinian of the Borgie area is compared and contrasted. Using various element plots (TiO 2 /SiO 2 ,TiO 2 /total Fe, CaO/Y, CaO/Ce, Rb/Sr), it is shown that the Moinian and Lewisian are clearly distinguishable. Furthermore the Borgie Lewisian can be divided into Scourian and Laxfordian areas on the basis of characteristic element ratios (K/Rb, K/Sr, K/Ba, Rb/Sr, Ba/Rb), the wider implications of which are briefly discussed.Keywords
