Ovenshine, A. T.; Winkler, G. R.; Andrews, P. B.; Gostin, V. A. (1975): Chemical analyses and minor element composition of Leg 29 basalts. Texas A & M University, Ocean Drilling Program, College Station, TX, United States, Initial Reports of the Deep Sea Drilling Project, 29 (Lyttleton, N. Z. to Wellington, N. Z.; March-April 1973), 1097-1102, georefid:1976-016990

Drilling on Leg 29 recovered basalts at five sites. Three of the basalts were from pillow flows, one from a massive lava flow, and one from an intrusion. No major differences between the rocks from the five sites are found in major oxide, normative mineralogical, and minor element composition. However, there are minor differences of unknown significance between the sites close to New Zealand and the sites close to Australia. Chemically, the Leg 29 basalts are intermediate in composition between oceanic tholeiites and oceanic alkalic basalts.
