Chronology and Geochemistry of Lavas from the Nazca Ridge and Easter Seamount Chain: an ∼30 Myr Hotspot Record

Ray, Jyotiranjan S.; Mahoney, John J.; Duncan, Robert A.; Ray, Jyotisankar; Wessel, Paul; Naar, David F. (Oxford University Press, 2012-07)

The Easter Seamount Chain and Nazca Ridge are two of the most conspicuous volcanic features on the Nazca plate. Many questions about their nature and origin have remained unresolved because of a lack of geochronological ...
Effective elastic thickness of the lithosphere along the Easter Seamount Chain

Kruse, Sarah E.; Liu, Zhengrong J.; Naar, David F.; Duncan, Robert A. (American Geophysical Union, 1997-12-10)

Bathymetry and gravity data collected during Legs 5, 6, and 7 of the 1993 GLORIA Expedition and the recently released 2-min altimetry-derived global gravity grid are used to determine the effective elastic thickness of t ...
