Mantle source heterogeneity and melting processes beneath seafloor spreading centers: The East Pacific Rise 18° - 19°S (1996)
Journal Article
Niu, Y., Waggoner, G., Sinton, J., & Mahoney, J. (1996). Mantle source heterogeneity and melting processes beneath seafloor spreading centers: The East Pacific Rise 18° - 19°S. Journal of Geophysical Research, 101(B12), 27711-27733. https://doi.org/10.1029/96jb01923

We present new major and trace element and Nd-Pb-Sr isotopic data on samples from the East Pacific Rise (EPR) axis and nearby seamounts in the Hump area, 18°–19°S. Most samples studied are normal mid-ocean ridge basalt (N-MORB); four samples from the...

Steady and non-steady state magma chambers below the East Pacific Rise (1996)
Journal Article
Batiza, R., Niu, Y., Karsten, J., Boger, W., Potts, E., Norby, L., & Butler, R. (1996). Steady and non-steady state magma chambers below the East Pacific Rise. Geophysical Research Letters, 23(3), 221-224. https://doi.org/10.1029/95gl00016

Volcanic rocks collected on flowline traverses on the flanks of the East Pacific Rise (EPR) document changes in axial magma chemistry with time, providing a record of the thermal history of axial magma chambers (AMC). We present data for a sample set... Read More about Steady and non-steady state magma chambers below the East Pacific Rise.

A history of the Easter Microplate, 5.25 Ma to Present (1995)
Journal Article
Rusby, R., & Searle, R. (1995). A history of the Easter Microplate, 5.25 Ma to Present. Journal of Geophysical Research. Solid Earth, 100, 12,617-12,640

GLORIA and other geophysical data are used to interpret the morphology and tectonic pattern of the Easter microplate. We model magnetic anomaly data and calculate spreading rates for use in Euler pole calculations. We calculate three-plate closure an...

Magmatism in the Garrett transform fault (East Pacific Rise near 13°27′S) (1995)
Journal Article
Hékinian, R., Bideau, D., Herbért, R., & Niu, Y. (1995). Magmatism in the Garrett transform fault (East Pacific Rise near 13°27′S). Journal of Geophysical Research, 100(B6), 10163-10185. https://doi.org/10.1029/94jb02125

The Garrett transform is characterized by recent (zero age) volcanic activity located within the active tectonic domain of the transform valley at depths greater than the 3500 m. This intratransform volcanic activity contributed to the formation of c... Read More about Magmatism in the Garrett transform fault (East Pacific Rise near 13°27′S).
