Title: Internally heated pressure vessels (IHPVs) - key experimental facilities to study crustal magmatism
Abstract: Internally heated pressure vessels (IHPVs) represent invaluable and crucial experimental tools to study crustal magmatic processes. However, although IHPVs have been established more than 50 years ago, the worldwide number of experimental labs still running them on a daily basis is limited despite the numerous scientific possibilities they offer.
In this talk, I will provide a general introduction to the working principles of IHPVs but also show some insights into the daily business of IHPV operation. IHPVs offer distinct advantages compared to other facilities that reach similar pressure ranges (e.g., piston cylinder presses or cold seal pressure vessels) and, thus, my presentation intends to motivate the FORCE community to intensify the incorporation of IHPV experiments in their future research projects.
In the second part of the seminar, I will present some of my own research exemplifying how we can use IHPVs to improve our understanding of phase equilibria in calc-alkaline magmatic systems. We conducted a systematic experimental study on the effect of various parameters (e.g. bulk magma composition, H2O content, temperature, and pressure) on crystallization systematics of basaltic magmas to improve our capabilities of predicting silicate mineral stability (e.g. for clinopyroxene or plagioclase) in arc systems.

Title: Pressure Effects on Trace Element Partitioning During Core Formation Abstract: Pressure effects on metal-silicate partitioning exist between 1 and 10 GPa for select, but not all, trace elements. Distinguishing the effect of pressure from other variables on activity coefficients and partitioning is important for determining whether relatively low-pressure experimental data (1 GPa) can be ...

Title: The Deep Earth Oxygen Cycle Abstract: Earth's mantle has been oxidized compared to its cosmochemical building blocks since the earliest Hadean. The origin of Earth's significant oxidative power is linked to Earth's initial differentiation, including processes in magma oceans, but these remain poorly understood. New ultra-high pressure (diamond anvil) experiments help illuminate the role ...

Title: Plate tectonics on Mars hindered by buoyant Martian eclogite Abstract: Mars lacks ongoing tectonic activities such as volcanism and mountain-building processes. Modern plate tectonic movements on the Earth's surface are driven primarily by the descent of subducted slabs into the mantle. Slab crust made of dense eclogite metamorphosed from the Mid-Ocean Ridge Basalt provides an important ...

Title: The slab in the lab: Simulating deep-focus earthquakes through transformational faulting at high P & T in olivine analogues Although nearly a century has elapsed since the discovery of deep earthquakes (~60-700 km), their fracture mechanism(s) has remained enigmatic; the pressures and temperatures at these depths should prohibit catastrophic failure and render rocks ductile. Nevertheless...

Abstract: The fast-paced discovery of exoplanets and novel materials at high pressure challenge experimentalists to expand the pressure-temperature range to probe material properties under extreme conditions. There have been significant advances in static and dynamic compression techniques in recent decades. A combination of static and dynamic compression data allows us not only to improve the ...
