One volcanology PhD position on *â??Magma-rock interaction: chemical-physical
processes and effects on eruption dynamicsâ??* is available at Dipartimento
di Scienze della Terra e Geoambientali, University of Bari, for foreign
(with degree obtained on foreign universities) students. Advisor of the PhD
is prof. Roberto Sulpizio (University of Bari), with co-tutorage of
dr. Antonio Costa (INGV, Bologna), and Prof. Diego Perugini (University of
Perugia). The successful candidate is expected to develop a *collaborative
research program* (see brief description in the following) straddling among
physical volcanology, numerical models, and petrology. The PhD will last
three years, with a net (after taxes) salary of around 13,500 Euro per year.
The selection of candidates is two-step: i) the candidates have to send a
cv, a letter of motivation, and a recommendation letter to Roberto
Sulpizio (Roberto.sulpizio@xxxxxxxx); ii) a selected number of candidates
will be invited to submit a formal application for the final selection
(deadline July 25, 2019). The documentation will be collected until July 12
(12:00, CET). Final selection is expected in August-September, 2019.
Short description of the research program.
The project focuses on studying the influence of magma-rock interaction on
eruption dynamics and, in particular, on how this interaction affects
the physical and chemical processes controlling rheology and ascent of
magma during a volcanic eruption.
Magma-rock interaction is an unavoidable process in the Earth
system. At any stage of their lifetime magmas do interact with solid rocks
in many different ways, from their formation in source regions to their
migration trough dykes, sills and conduits during their ascent to the Earth
surface.
Here, we define as magma-rock interaction only the physical and
chemical processes related to the mechanical and thermal contact between
rocks and magma, and incorporation of solid country rocks from the magma.
We do not take into account any interaction with fluids hosted in country
rocks, like water reservoirs or hydrothermal systems. This choice is
motivated by the fact that including all possible processes related to
magma-rock interaction would imply addressing processes of paramount
complexity, which are intractable within a three-year project.
In the defined domain of investigation, we aim at studying the
interaction of magma with the surrounding country rocks, and how it
influences magma ascent, degassing, and eruption style.
Best wishes,
Roberto, Antonio, and Diego
