Abstract
  • Abstract: IODP 351 cruise to the back arc region of the Izu Bonin contained cores with tephra layers intermitted within. These tephra layers under went electron micro probe analysis to gather major earth element abundances in order to put a parameter of a. where did the tephra originate from (volcanic source) b. how variant are the samples within each tephra layer. Through comparison of total alkali, K₂O, Fe, Mg, trends appear in the data though a clear origin cannot be determined. Though a strong correlation was found with Izu Bonin back arc samples that had been retrieved from IODP 728. The variation of composition within each layer was depicted through a 1σ standard deviation upon a Smithsonian standard rhyolitic tephra sample. The variation plots revealed that the majority of the samples experienced minor (1σ) variation within each layer, with less then 10% experiencing a high degree of variation. This supports the assumption that each layer contains the tephra from one event.
