Geodynamic Processes at Rifting and Subducting Margins

Due Date: 07/27/2017

The National Science Foundation’s (NSF) GeoPRISMS (Geodynamic Processes at Rifting and Subducting Margins) Program investigates the coupled geodynamics, earth surface processes, and climate interactions that build and modify continental margins over a wide range of timescales. These interactions cross the shoreline and have applications to margin evolution and dynamics, construction of stratigraphic architecture, accumulation of economic resources, and associated geologic hazards and environmental management.

The GeoPRISMS Program includes two broadly integrated science initiatives - Subduction Cycles and Deformation and Rift Initiation and Evolution - linked by five overarching scientific topics and themes, where transformative advances are likely to occur in the next decade, and where a focused scientific program could be most effective. These overarching science topics include:

  1. Origin and evolution of continental crust
  2. Fluids, magmas and their interactions
  3. Climate-surface-tectonics feedbacks
  4. Geochemical cycles
  5. Plate boundary deformation and geodynamics.

GeoPRISMS investigations should be aimed towards a comprehensive understanding of the observable system properties, and can include theoretical, numerical and experimental studies, as well as field investigations. GeoPRISMS objectives must be achievable with existing technological capabilities or reasonable increments beyond present capabilities, but should be open to a range of integrative and interdisciplinary community experiments. Finally, broader impacts such as societal relevance, contribution within the discipline, and education and outreach are important elements of the GeoPRISMS Program.
