Magma geochemistry

The study of the chemical and isotopic compositions of past and present melts is an important step for a better knowledge of the structure and dynamics of the Earth, essential for the prevention of natural hazards. To study magma composition, we used magmatic minerals or melt inclusions, small droplet of melt trapped during crystal growth. In situ measurements, using ion probe, for stable isotopes, volatiles and trace elements in these materials allow accessing small to large scale chemical variations and then documenting precisely different magmatic processes.
