MARGINS Rupturing of Continental Lithosphere

What is Rupturing Continental Lithosphere?

Although much progress has been made over the last few years in understanding the kinematics of continental lithosphere deformation, it is agreed that the physics by which the continental lithosphere deforms is not well understood, nor is the manner in which strain is partitioned, either spatially or temporally, and the timing, composition, spatial distribution and melting depth of rift-related magmas. The focused study of these processes form the foundation of the Rupturing Continental Lithosphere (RCL) initiative.

The five overarching themes to be studied comprise:

  1. How does the strength of the lithosphere evolve during rupturing?
  2. How is strain partitioned during lithospheric rupturing?
  3. What is the role of magmatism (and volatiles) during extension and in the transition to sea-floor spreading and what is the relationship between magma petrogenesis and the deformation magnitude and history?
  4. What is the stratigraphic response to lithospheric rupturing?
  5. How are fluid fluxes modified or controlled by lithospheric rupturing?
