Whole rock major and trace element analyses of tephras from IODP Site U1437 and dredged rocks from the surrounding area, Izu-Bonin rear-arc

XRF and ICP-MS data obtained on whole rock samples of core (obtained via drilling on IODP Expedition 350 at Site U1437, Izu-Bonin rear-arc; Igneous Unit 1) and dredged rhyolites from the surrounding area (obtained via dredging using the R/V Moana Wave in 1995, see Hochstaedter et al., 2000).

X射线荧光光谱法（XRF）与电感耦合等离子体质谱法（ICP-MS）数据，来源于两类样品：其一为岩心全岩样品，通过综合大洋钻探计划（IODP）第350航次在伊豆-小笠原弧后U1437站位钻探获取，属于火成岩单元1；其二为周边区域经 dredge采集的流纹岩，1995年由R/V Moana Wave号科考船通过 dredge作业获得（详见Hochstaedter等人，2000）。
