Z. to Wellington, N. Z.; March-April 1973)1097-1102Drilling 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.completedIgneous and metamorphic petrologybasaltschemical compositionclassificationDeep Sea Drilling Projectigneous rocksintrusionslavalava flowsLeg 29major elementsmarine geologymineral compositionminor elementsPacific Oceanpetrologypillow lavaSouth PacificsouthwestSouthwest PacificTasman Seavolcanic rocksWest Pacificurn:org.iodp:exp:29urnlargerWorkCitationcampaignEnglishgeoscientificInformation143.0000177.0000-57.0000-30.0000Tasman Seaapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://deepseadrilling.org/29/volume/dsdp29_37.pdfdownload
