Mantle temperature variation and plate spreading rate variation have been considered to be the two fundamental variables that determine the extent of mantle melting and ocean crust production. Along the length of a 200 km portion of the Mid-Atlantic...

Origin of enriched-type mid-ocean ridge basalt at ridges far from mantle plumes: The East Pacific Rise at 11°20′N (1999)
Journal Article
Niu, Y., Collerson, K., Batiza, R., Wendt, I., & Regelous, M. (1999). Origin of enriched-type mid-ocean ridge basalt at ridges far from mantle plumes: The East Pacific Rise at 11°20′N. Journal of Geophysical Research, 104(B4), 7067-7087. https://doi.org/10.1029/1998jb900037

The East Pacific Rise (EPR) at 11°20′N erupts an unusually high proportion of enriched mid-ocean ridge basalts (E-MORB) and thus is ideal for studying the origin of the enriched heterogeneities in the EPR mantle far from mantle plumes. These basalts... Read More about Origin of enriched-type mid-ocean ridge basalt at ridges far from mantle plumes: The East Pacific Rise at 11°20′N.

Mantle source heterogeneity and melting processes beneath seafloor spreading centers: The East Pacific Rise 18° - 19°S (1996)

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

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.

Magmatism in the Garrett transform fault (East Pacific Rise near 13°27′S) (1995)
Journal Article

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).

Magmatic processes at a slow spreading ridge segment: 26°S Mid-Atlantic Ridge (1994)

We present new data on the mineralogy, and major and trace element compositions of lavas dredged along a segment of the Mid-Atlantic Ridge at ∼26°S. This segment is bounded on the north by the Rio Grande transform and on the south by the Moore discon...

Chemical variation trends at fast and slow spreading mid-ocean ridges (1993)

We examined an expanded global data set of mid-ocean ridge basalt (MORB) major element analyses. In agreement with previous results, we show that slow spreading ridges tend to have more primitive (high Mg/Fe) lavas than fast spreading ridges. Fractio...

We present a new method for calculating the major element compositions of primary melts parental to mid-ocean ridge basalt (MORB). This model is based on the experimental data of Jaques and Green (1980), Falloon et al. (1988), and Falloon and Green (...
