V52B:
Mineralization, Metasomatism, and Mass Transfer Associated with Crustal Magmas I


Session ID#: 9803

Session Description:
Society is increasingly relying on mineral resources for high technology and green industries.  The aim of this session is to explore advances made on the partitioning behavior of elements during fluid-rock interaction and the effects of metasomatism in mineralization associated with crustal magmatic processes.  Advances have been made in studies of porphyry to epithermal ore deposits in volcanic and orogenic provinces using analytical approaches such as geochronology, isotopic analyses, and in situ LA-ICP-MS analyses of fluid inclusions.  In contrast, rare earth element and other so-called critical element deposits such as peralkaline granitic, alkaline syenitic, carbonatites, pegmatites, and the IOCG related systems are still poorly understood.  Metasomatic zones developed during ore forming processes in magmatic-hydrothermal systems yield key insights for element partitioning and mass transfer in the crust.  We welcome contributions showing advances from field studies, numerical modeling, and experimental work.
