Engel, A.E.J., Engel, C.G. and Havens, R.G. (1965). Chemical characteristics of oceanic basalts and the upper mantle. Geological Society of America, Bulletin 76(7): 719-734.

Analytical data coupled with the field relationships indicate that the alkali-rich basalts are derivative rocks, fractionated from the oceanic tholeiites by processes of magmatic differentiation, and that the oceanic tholeiites are the principal or only primary magma generated in the upper mantle under the oceans.' An appendix lists the locations and gives brief descriptions of the basalt samples from the Atlantic and Pacific Ocean basins, whose chemical composition has been collated within the paper.
