Deep explosive volcanism on the Gakkel Ridge and seismological constraints on shallow recharge at TAG active mound
… at the site. The morphology and distribution of volcaniclastic deposits observed on the seafloor at depths of ~3800 m, greater than the critical point for steam generation, are consistent with having formed by explosive discharge of magma and CO2 from source vents. Microearthquakes recorded on a …

Probing the interior of an active volcano: Three-dimensional seismic tomography at Montserrat
… that make up the island, the slower surrounding volcaniclastic deposits and pelagic sediments, and the underlying upper crust. Analysis of field recordings and synthetic waveforms calculated with a viscoelastic finite-difference method indicates that the high-velocity cores correspond to a …

Characterization of a volcanically impacted, overfilled continental rift basin within the southeastern Jemez Mountains, New Mexico
… with about 550 m of lava and primary pyroclastic deposits and minor fluvial sediments. As a result, little or no coarse-grained epiclastic sediments were shed from adjacent footwall highlands and deposited into the basin along its margins, which is a trait of conventional rift basin models. …
