This work investigates the petrogenetic processes that result in the creation of new oceanic crust beneath the Arctic Ocean. Since the initial exploration of this region by an international group of researchers I helped lead in the early 2000's, significant work has illuminated the chemical and physical processes that created the sea floor by studying the mineral chemistry of olivine, pyroxenes and spinel contained in the rocks recovered from the sea floor. These have been modified by adiabatic partial melting and disequilibrium melt-rock reaction processes. The results are compared to recent work on sea floor spreading in the Shikoku basin of the western Pacific Ocean.
