Abstract

Plate boundaries are locations where two tectonic plates meet. New plate boundaries form by rifting an existing plate at places that are weak. This project will focus on the Davie Fracture Zone in the Mozambique Channel. The study will integrate several datasets to study how inherited oceanic structures control the development of incipient tectonic plate boundaries. Methods include machine learning approaches. The…
