Abstract
Appinitic and syenitic intrusive masses occupy an explosion-breccia pipe which formed as the result of explosions of gases rising ahead of a volatile-rich basic magma. Transfusion of quartzite, as described by Reynolds (1936) from Colonsay, may be the origin of the syenitic masses and syenitic veins.
