Tectonic reconstructions of the Cretaceous paleo-Pacific system show several significant tectonic and magmatic events, including the formation of several spreading centers, microplates and intra-oceanic arcs, and the initiation (>76–81 Ma) of magmatic activity which formed the Emperor-Hawaiian se...
