GMPV3.4Progress in Metamorphic Geology: Petrochronology (including GMPV Division Outstanding ECS Award Lecture)
|Convener: Pierre Lanari | Co-Conveners: Emilie Janots , Silvio Ferrero|
Unraveling the nature of crustal growth and mountain building processes across Earth’s dynamic history relies on integrated studies involving the reconstruction of pressure-temperature-time (P-T-t) -paths from preserved metamorphic assemblages and their textures. This session aims to deepen our understanding of petrogenetic processes based on the evidence preserved in metamorphic rocks. Part of this session will be dedicated in particular to studies on “petrochronology” that aims to quantify the conditions and dynamics at which metamorphic processes and deformation in Earth’s lithosphere operate. To read and interpret the rich archive of such processes as preserved in metamorphic rocks, advances in petrological analysis are combined with high-resolution geochronology.
This session welcomes recent advances made in the development and application of these techniques and their tectonic and petrogenetic implications. Contributions expanding present analytical limitations are encouraged, as are case studies ranging from the grain-, hand-sample, outcrop and orogen scales.
