(Appendix 1) Major and trace element content of bulk sediment of ODP Hole 121-758A@en

Sediment depth is given in mcd. Major and trace elements were measured by ICP-MS (VG PlasmaQuad II+) with a typical precision of ±5%. Indium internal standard solution was added to each sample prior to analysis. The accuracy of the analysis was assessed running the BR and BE-N rock standards.沉积物深度以mcd（米复合深度，meter composite depth）为单位表示。常量元素与微量元素采用电感耦合等离子体质谱法（Inductively Coupled Plasma Mass Spectrometry，ICP-MS）结合型号为VG PlasmaQuad II+的仪器进行测定，典型测定精密度为±5%。分析前需向每份样品中加入铟内标溶液。本分析的准确度通过对BR和BE-N岩石标准物质的测定进行评估。
