Burpala



Burpala is an alkaline massif of 220km² in the northern Baikal area, Russia. Syenite pegmatites, nepheline syenites, microcline-quartz-albite-aegirine-riebeckite dykes are intruded in sedimentary volcanogenic rocks. The intrusion is zoned, from the outside being granosyenites, quartz syenites, peralkaline syenites, and pulaskites. Fenitisation is common.
Part of the mineral list is from the „Encyclopedia of Minerals“.
