Origine de la diversité géochimique des magmas équatoriens : de l'arc au minéral

Origine de la diversité géochimique des magmas équatoriens : de l'arc au minéral

Les laves d'arc ont une géochimie complexe du fait de l'hétérogénéité des magmas primitifs et de leur transformation dans la croûte. L'identification des magmas primitifs dans les arcs continentaux est difficile du fait de l'épaisseur de la croûte continentale, qui constitue un f...
