9. Conclusions
In this XL019 paper, we have presented several lines of field, petrographic, geochemical and geophysical evidence that point to the formation of the Doros Complex by multiple closely spaced influxes of crystal-bearing magmas (magma mushes), rather than from the post-emplacement differentiation of a single batch of liquid magma. We envisage seven distinct major injections of magma, each with phenocryst contents between 5% and 55%, as well as several smaller pulses. These findings represent a departure from the traditional single-pulse liquid model for the formation of layered mafic intrusions and are in line with the ‘magmatic mush column’ hypothesis proposed by Marsh (2004). This emphasises the importance of open-system processes and the role of phenocryst-bearing magmas in the evolution of mafic magma systems.
