Abstract

Alkaline syenites from the Ruri Hills in Western Kenya are described, and the hypothesis advanced that their present constitutions have been developed partly by replacement. The syenites occur as dykes and small plugs associated with ring complexes of carbonatites which, together with agglomerates, largely form the hills, and are presumed to be congeneric with an ijolite mass at Usaki.
