Abstract

Result from this study may give new insights into the potential evolution of magma mixing processes in plutonic environments. In fact, it is suggested that the viscous fingering may be a very important process contributing to drifting the viscosity ratio between magmas towards low values and, hence, towards the best rheological conditions to trigger widespread mixing processes in the magma chamber. In conclusion, the present paper shows that combining fractal geometry measurements on natural rocks and fluid-mechanics experiments may help to shed new light into geological processes whose knowledge may open new frontiers in the study of igneus systems and their evolution in time and space. - (NF)
