The International Orogenic Lherzolite Conference aims to unite specialists in mantle processes to key orogenic mantle peridotite (and related rocks) outcrops worldwide. The conference provides a platform to exchange knowledge and engage in discussions regarding the latest advancements in the processes occurring in the upper mantle and at the transition between the upper mantle and the lower crust. Contributions typically cover a wide range of topics, including melting processes, crustal recycling, significance of mafic lithologies, metasomatism, lithosphere evolution through rejuvenation and refertilization, supra-subduction fluid/melt/deformation processes, feedbacks between deformation and melt segregation/migration, field and experimental studies on mantle/lower crust rocks deformation, geophysical imaging of the Moho transition, mantle structures and flow, or mineral resources related to mantle rocks.
