 note = {application/pdf, Rangitoto Island is the largest and youngest volcano in the Auckland Volcanic Field, New Zealand. It is the only volcano that produced tholeiitic basalt. All the others are alkali basalt or basanite. Sixteen young lava flows overlying the older lava flows were mapped on the basis of aerophotographs and field observations. Thirteen samples from 12 lavas from among 17 lava flows ( 16 young + one old) were analyzed in order to investigate the variation of chemical compositions of the source magma. The compositional variations within Rangitoto basalt is caused by the accumulation of olivine and clinopyroxene phenocrysts.},
