With this session we offer a platform for contributions using geochronological methods for resolving processes in ancient and modern magmatic systems, from deep crust to the surface, from melt accumulation, fractional crystallisation and melting in deep-seated reservois, to melt and crystal transport into the middle and upper crust, processes at the origin of volcanic eruptions, as well as all temporal aspects of metal transport, precipitation and crystallization in ore deposits at lithosphere-scale.
