Fig. 8: Schematic model of the formation and melt ascent processes of petit-spot and DAP volcanoes.

From: The mantle structure below petit-spot volcanoes

Fig. 8

The majority of petit-spot melt at least plausibly ascend as carbonatitic melt after carbonatite/silicate immiscibility. The melts excluding DAPs stack in the middle or lower asthenosphere. The sources are originated from asthenosphere with recycled materials.
