Description:
The Campi Flegrei volcanic system is certainly a remarkable case study for
what concerns magma chamber dynamics. In fact, its magmatic and volcanic
history appears to have been largely driven by chamber processes like fractional
crystallization, magma mixing, and volatile degassing. These processes have been
intensely investigated with a variety of approache
s.
Here we employ physico-
mathematical modelling and numerical simulations in order to study the dynamics
of magma convection and mixing in a vertically extended, geometrically complex,
compositionally heterogeneous magmatic system representing a schematic
simplification of an overall picture emerging from previous studies
at Campi
Flegrei
. Although clearly a simplification, a number of first order characteristics of
possible real magmatic systems at Campi Flegrei are accounted for, including the
more chemically evolved, partially degassed nature of magmas emplaced at
shallow depths, and the likely occurrence of multiple reservoirs with different
depth, size and shape which can be connected at certain stages during system
evolution, allowing deeper, CO
2
-rich magmas to rise and rejuvenate the shallow
magmas.
