The influence of water-saturation on the strength of volcanic rocks and the stability of lava domes
Marie Estelle Solange Violay, Michael Heap
The rocks forming a volcanic edifice or dome are typically saturated or partially-saturated with water. However, most experiments aimed at better understanding the mechanical behaviour of volcanic rocks have been performed on dry samples, and therefore mos ...
2023Taking the pulse of volcanic eruptions using plagioclase glomerocrysts
Anders Meibom, Stéphane Laurent Escrig, Anders McCarthy, Pierre Vonlanthen
Crystallization timescales in subvolcanic systems and the consequences of interaction between ascending magmas and gases remain largely unconstrained, as do links between these processes and monitoring signals at restless volcanoes. We apply diffusion chro ...
ELSEVIER2020Short magmatic residence times of quartz phenocrysts in Patagonian rhyolites associated with Gondwana breakup
Anders Meibom, Stéphane Laurent Escrig, Lukas Baumgartner, Susanne Seitz
A key parameter in the study of magma evolution is the time scale on which magmatic processes occur. Using nanoscale secondary ion mass spectrometry (NanoSIMS), SIMS, and cathodoluminescence (CL) analyses, we have measured titanium (Ti) diffusion profiles ...
Geological Society of America2016Ductile flow in sub-volcanic carbonate basement as the main control for edifice stability: New experimental insights
Limestone in volcanic basements has been identified as a hazard in terms of edifice stability due to the propensity of calcite to decompose into lime and CO2 at high temperatures (>600 °C), causing a decrease in mechanical strength. To date, such hypoth ...
