Dear All,
Carolina, Giacomo and I would like to invite you to submit abstracts to, and to attend the following session (TS5.2/GMPV5.12), which will be held at the upcoming EGU meeting in Vienna, Austria (17th-22nd April 2016) :
Magma-tectonic processes in continental rifts: combining perspectives from ancient rifted margins and zones of active spreading
Continental break-up is commonly associated with the development of normal faults, the formation of sedimentary rift basins, and magmatic activity. Interactions between these processes control the geometry and connectivity of magma conduits
and reservoirs, potentially influencing the entire margin evolution and the transition to seafloor spreading. Defining plumbing system structure can therefore provide important insights into: (1) the stage of continental rifting; (2) the chemical evolution
of magma and its migration through the lithosphere; (3) host rock deformation induced by magma movements; and (4) volcanic eruption locations and styles. However, limitations in exposure at the Earth's surface makes reconstructing magma plumbing systems challenging.
It is therefore important to integrate field observations with data that provide insights into magma pathways and storage. In areas of active continental break-up or oceanic spreading, indirect analytical approaches commonly involve: (1) ground deformation
data (e.g., InSAR and GPS) to define the geometries and volumes of magma emplacement; (2) petrological and geochemical data to asses magma contamination, residence times, crystallization histories, and melt source conditions; and/or (3) mapping both crystallized
and melt intrusions using geophysical techniques such as potential field, magnetotellurics and seismicity. Conversely, seismic reflection data has revolutionized our understanding of plumbing systems in rifted margin settings. This session aims to bring together
a range of Earth Scientists, who employ different techniques, to discuss magma-tectonic interactions observed in areas of active or ancient lithospheric extension. We particularly welcome contributions that asses various magma-tectonic processes, using different
geological and geophysical techniques, occurring during the active break-up of East Africa or Iceland or the ancient extension and subsequent evolution of rifted margins. We are particularly interested in works that attempt to bridge the gap between active
and ancient break-up studies.
The deadline for submission of abstracts is January, 13th, 2016.
