Rapid magmatic processes drive persistently active volcanism

IN43D-0108: Magmatic volatiles as an amplifier of centrifugal volcanism

Millisecond fluctuations in length of day over multiple decades may induce fluctuations in flow of magma to the surface. We propose that the same magmatic volatiles that greatly amplify volcanic eruptions can also amplify these minute magmatic fluctuations sufficiently to be detected in sea surface temperature.

Magmatic Processes : Physicochemical Principles

The viscosities of eight melt compositions in the System albite-H20-F20_1 have been determined at high pressure and temperature. Measurements were performed using the falling sphere method at 1000-1600°C and 2.5 to 22.5 kbar. Fluorine and water strongly decrease the viscosity of albite melt at all pressures and temperatures investigated. The viscosity of a fluorine-bearing albitic melt decrease...

Mud volcanism: Processes and implications

Mud volcanoes can be large and long lived geological structures that morphologically resemble magmatic volcanoes. Because of their capricious behaviour and their spectacular morphology and landscapes, mud volcanoes have attracted attention since antiquity. More recently, mud volcanoes have become the focus of extensive studies for natural science research, including geologists and biologists. M...

Magmatic processes that produced lunar fire fountains

[1] Reanalysis of the Apollo 15 A, B, and C green glass beads from slide 15426,72, led to the discovery of patchy, highly vesicular glass rims adhering to beads. These rims are high in S and Ni and low in MgO, but otherwise compositionally similar to the green glasses. We find that these rims represent a unique melt composition that places constraints on lunar magmatic processes. Combining the ...
