    Petrogenesis of the False Bay dyke swarm, Cape Peninsula, South Africa
    (2012) Backeberg, Nils Rainer
    The False Bay dyke swarm is the southern-most set of Early Cretaceous dolerite dyke intrusions along the western margin of southern Africa associated with rifting of Gondwana and opening of the South Atlantic Ocean. Previous work highlighted the evolution of a single magma type from olivine-tholeiite basalt to ferro-tholeiite andesite. This thesis presents detailed field observations of each dyke in the False Bay - Cape Peninsula region and the focus of the study is on the finer details of the differentiation process to define combined assimilation and fractional crystallisation models.
