Ponta Delgada, 4-9 August 1980.Major element electron microprobe analyses of over 100 dredged samples of basalt glass from the East Pacific Rise and nine young isolated seamounts near the Rise are presented along with petrographic data for the samples. These data indicate that most suites of samples from seamounts are fractionated suites of low-K₂O mid-ocean ridge basalt similar to many described previously. In addition, however, some seamount lavas differentiate toward higher K₂O, TiO₂ and other incompatible element enrichment without correlation with Mg/Fe ratios. These two types of chemical abundance variation trends do not correlate well with size, age or tectonic settings of the seamounts, however, the absolute amount of chemical diversity observed in the lavas of each seamount does correlate with these other variables. The data indicate that location on fracture zones is neither a necessary or sufficient condition for great chemical diversity of seamount lavas, however, seamounts on fracture zones tend to be large in size. On the other hand, relatively great age (> 3.0 m.y.) and great size (> 200 km³) are sufficient but not necessary conditions for such seamount lava diversity. These patterns may be interpreted in terms of the evolution of young oceanic central volcanoes.Universidade dos AçoresRepositório da Universidade dos AçoresBatiza, RodeyO'Hearn, T.2018-11-28T13:29:52Z1982-071982-07-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.3/4898engBATIZA, Rodey; O’HEARN, T.
