Ocean Drilling Program Leg 193 drilled two sites at the PACMANUS hydrothermal field, Snowcap and Roman Ruins. We investigated electrical properties of core samples recovered from these sites to study the effect of hydrothermal ...

Raoul Volcano in the northern Kermadec arc is typical of volcanoes in oceanic subduction systems in that it is composed mainly of low-K high-Al basalts and basaltic andesite. However, during the last 4 ka Raoul Volcano has ...

Compositional heterogeneity (56–64 wt% SiO2 whole-rock) in samples of tephra and lava from the 1986 eruption of Augustine Volcano, Alaska, raises questions about the physical nature of magma storage and interaction beneath ...

Dehydration experiments on basaltic, andesitic and dacitic glasses with 1.1, 0.7 and 1.0 wt.% total water, respectively, were performed at 400-675 °C and 0.1 MPa. The dehydration rates were measured by in situ infrared ...
