Orientation of the eruption fissures controlled by a shallow magma chamber in Miyakejima
Frontiers in Earth Science, 2016 Orientation of the eruption fissures and composition of the lavas of the Miyakejima volcano indicate tectonic influence of a shallow magma chamber on the distribution of eruption fissures.

A 5-km-thick reservoir with > 380,000 km3 of magma within the ancient Earth's crust
Scientific Reports, 2022 Several recent studies have argued that large, long-lived and molten magma chambers may not occur in the shallow Earth’s crust. Here we present, however, field-based observations from the Bushveld Complex that provide evidence to the contrary.

Magmatic karst reveals dynamics of crystallization and differentiation in basaltic magma chambers
Scientific Reports, 2021 An understanding of magma chamber dynamics relies on answering three important yet highly controversial questions: where, why, and how magma chambers crystallize and differentiate.

Geometry of the magma chamber beneath Damavand volcano (N Iran) from a joint study of gravity and magnetic data [PDF]
International Journal of Mining and Geo-EngineeringImaging the intra-sediment magma chamber in the Damavand region, northern Iran, is beyond the resolution of the local seismic observations. Gravity anomalies can precisely image the lateral extension of magma reservoir.
