Xenolith localities are scarce in Scandinavia, none being known in Denmark or in Finland. The chapter therefore only deals with Sweden and Norway. This region is divided, roughly equally, into a Precambrian craton and the Caledonian orogenic belt (approx 500- 350 m.y.). Most of the xenolith localities are of two general types: alkaline lamprophyres associated with carbonatites, and basaltic dykes, plugs and diatremes related to rifting processes. The first type includes the Kalix dykes (approx 1600 m.y.) and the central complexes at Fen and Alno, both approx 600 m.y. old. The basaltic localities include dyke swarms and plugs in S Sweden and SW Norway (approx 225 m.y.), and Quaternary basaltic volcanoes and diatremes of NE Spitsbergen. A third type of occurrence is represented by xenolith-bearing hornblende gabbro dykes in N Norway, which were intruded into the base of the crust during the Caledonian orogeny (approx 500 m.y.). -J.M.H.
