Initial extension controls later rift development and ultimately the structure of rifted margins. This project quantifies rift processes within the Gulf of Corinth, a rare example of rifting at its earliest stage, by comprehensive integration of marine geophysical datasets collected by multiple groups since 1995 to generate a framework of stratigraphy and fault networks offshore. This allows investigatation of very early rift evolution at a range of scales by generating a high resolution analysis and new chronological model of the syn-rift stratigraphy within the active rift and a detailed rift fault network, including details of fault activity (hence hazard potential), growth and interaction. Together these components will be used to develop a detailed history of rift evolution in space and time at a resolution not generated before within a continental rift system. The project is linked to proposed scientific ocean drilling (IODP) in the Corinth Rift, Greece.
