Convergent plate margins are important places for material and energy recycling of the Earth, in particular major sites for continental growth, reworking, and recycling. They exhibit as narrow belt structure in the rigid outer layer of the Earth, corresponding to subduction zones at lithospheric mantle depths and orogenic belts at crustal depths. The type, geometry, and thermal structure of subduction zones have critical impacts on subduction processes and nature of products, resulting in a variety of magmatic rocks and ore deposits at convergent margins. Identification and classification of the physical structure and chemical variation at convergent margins as well as confirming their correlation with specific subduction types and stages are of pivotality to understand the spatiotemporal interaction between asthenosphere and lithosphere in orogenic belts. For places where magmatic arcs get partially or entirely destroyed by surface and/or subduction erosion, adjacent sedimentary rocks are ideal geological records for paleotectonic reconstruction.
The geodynamics at convergent margins entail multiple processes and multi-scale mechanisms, with interaction between the crust and mantle. In recent years, there is a growing body of new techniques (e.g., non-traditional stable isotope and machine learning) that have been applied to unveil more detailed geological processes at subduction zones. Therefore, this Research Topic aims to bring together multi-disciplinary and state-of-the-art studies on the applications of geochronology, low temperature thermochronology, geochemistry, isotope, numerical modeling, machine learning, and big data to scrutinizing the dynamics and effects of subduction initiation, subduction processes (switching between advancing and retreating subduction), and collision between continents.
This Research Topic welcomes Original Research and Review articles to address the following issues, but are not limited to:
• Magmatism and metallogenesis related to oceanic lithosphere subduction
• Magmatism and metallogenesis related to continent subduction
• Continental growth, reworking, and recycling
• Evolution of sedimentary basins at convergent margins
• Modelling orogenesis and orogenic processes
• Surface process at convergent margins
• Deep mantle dynamics
• Exhumation and burial history of related intrusions, basins, and deposits
• Mechanisms and effects of subduction initiation
