Abstract
Xenoliths of Appin limestone occur in the Ballachulish granodiorite at an outcrop southwest of Kentallen station, near Loch Linnhe, western Scotland. Potash-rich pyroxene-bearing rocks have been developed around the inclusions by transfer of silicon, aluminum, iron, and sodium from the magma, and of calcium from the xenoliths. The modified magma, enriched in potash, crystallized as a potassic syenite.
