Magma mingling : Die hydrodynamische Genese magmatischer Dispersionen
… Silikatschmelzen treten im gesamten Spektrum magmatischer Aktivität auf. Dabei kann es sowohl zu Magma mingling-, als auch zu Magma mixing-Prozessen kommen. Magmatische Enklaven und Dispersionen sind dabei Zeugen der ehemaligen Interaktion und Vermischung der beteiligten Schmelzen. Diese …

Significance of magma mingling and mixing during the formation of the host-rock successions of Archean massive sulfide deposits in the Noranda camp, Abitibi subprovince, Quebec, The
… cryptodome is best explained by a process of magma mingling. Mingling presumably occurred through synchronous emplacement of the felsic feeder of the cryptodome and a mafic dike along a synvolcanic fault. The host rock succession of the Quemont deposit primarily comprises coherent rhyolite and …

The consequences of gas slug ascent in a stratified magma on Strombolian eruption dynamics
… ascent through relatively low-viscosity magma within the volcanic conduit. However, this paradigm was forged when the complex rheology of the magma at Stromboli, the model-type volcano for this activity, was still poorly constrained. Textural and petrological evidence has recently …

Geochemical and petrological investigation into the magmatic system at Soufrière Hills Volcano, Montserrat.
… Hills Volcano, Montserrat exhibit evidence for magma mingling, related to the intrusion of mafic magma at depth. The processes of mass transfer and flux of material involved in the interaction between mafic and silicic magmas are crucial for understanding eruption dynamics. Detailed textural, …

Intense Shallow Magma Sediment Mingling within Dikes at Guffey Butte Maar, Idaho
The interactions between magma and shallow unconsolidated sediments on the way to the surface influences the eruption behavior and products. Phreatomagmatic eruptions are a result of the interaction of magma and water or wet sediment and their deposits are evidence of this interaction. The relative …

Historic and prehistoric volcanic activity on St Kitts and Nevis, West Indies: Controls on future hazard
… been analysed to characterise the nature of the magma storage conditions below both islands, and to understand the styles of the most recent eruptions. These geochemical analyses have shown that open-system processes dominated the magma storage conditions at both St Kitts and Nevis, and recharges …
