Gravity Field Reconstructions of the Southwest Pacific

Karen Marks and Joann Stock have used a novel approach to chronicle the development of plate boundaries in the Southwest Pacific during the early Tertiary. We used state-of-the-art marine gravity fields derived from ERS-1 and Geosat satellite altimeter data in combination with magnetic anomalies identified from ship surveys to reconstruct the gravity fields. These reconstructions reveal much about the configuration of plate boundaries and the evolving plate tectonics that existed in the past, as well as explain the seafloor structures and geophysical data observed today. Our results are published in Early Tertiary Gravity Field Reconstructions of the Southwest Pacific, Earth and Planet. Sci. Letts., 152, 267-274, 1997.
