Calcium stable isotopes of Tonga and Mariana arc lavas and implications for slab fluid-mediated carbonate transfer in subduction zones

The Table 1 shows Ca isotopes and selected major and trace element compositions  of the Tonga rear arc and Mariana arc lavas.

Supporting imformation includ Figure S1 and Table S1

Figure S1 shows the δ44/42Ca‰ versus δ43/42Ca‰ in all samples and reference materials measured by Nu Plasma 1700 MC-ICP-MS in GPMR.

Table S1 lists the major and trace element contents of NW Rota-1 and Esmeralda Bank samples from Mariana arc. Major elements are tested on board and trace elements are measured by ICP-MS in GPMR.

表1展示了汤加弧后区与马里亚纳弧熔岩的钙同位素组成，以及选取的主量与微量元素组成。

支撑材料包含补充图S1与补充表S1。

补充图S1呈现了所有待测样品与参考物质的δ44/42Ca‰与δ43/42Ca‰的对应关系，相关测试由GPMR实验室的Nu Plasma 1700型多接收电感耦合等离子体质谱（Multi-collector Inductively Coupled Plasma Mass Spectrometry, MC-ICP-MS）完成。

补充表S1列出了马里亚纳弧NW Rota-1与埃斯梅拉达浅滩样品的主量与微量元素含量。其中主量元素为现场船载测试所得，微量元素则由GPMR实验室的电感耦合等离子体质谱（Inductively Coupled Plasma Mass Spectrometry, ICP-MS）完成测定。
