Structural Restoration and Balancing in Extensional and Deltaic Margins Tectonic Settings


COURSE AND WORKSHOP

February 24 - 28, 2019

Instructor : Catalina Luneburg, Ph.D.


WHO SHOULD ATTEND

Geologists, Geophysicists, Explorationists, Supervisors and Managers.

COURSE OUTLINE


Restoration and balancing techniques are critical for the validation and quality of structural interpretations as well as the unraveling of the tectonic history of a region. In this course participants will learn the concepts of restoration and balancing through practical examples and regional analyses. The course focusses on extensional tectonic settings studying the architecture and development of rifts to passive margins including strike-slip systems, deltaic margins, basin inversion and salt basins. Extensional structures such as normal fault systems, growth faults, linked fault systems and ramp structures are restored using balancing techniques such as fault prediction and kinematic restorations.
