资源简介:
Supplementary Data: <b>SD1:</b> Sample source, stratigraphical unit, location, age, TAS ID and type. <b>SD2:</b> Major oxide compositions, weight loss on ignition (LOI), and minor and trace element concentrations of the lavas of Taranaki from this study. <b>SD3:</b> Major oxide concentrations of samples from Taranaki from literature (Price <i>et al.</i> 1992, 1999; Stewart <i>et al.</i> 1996; R. B. Stewart pers. comm. 2018; Zernack <i>et al.</i> 2012). <b>SD4:</b> Minor and trace element concentrations of samples from Taranaki from literature (Price <i>et al.</i> 1992, 1999; Stewart <i>et al.</i> 1996; R. B. Stewart pers. comm. 2018; Zernack <i>et al.</i> 2012). <b>SD5:</b> EPMA spot analyses of mineral crystals from this study. <b>SD6:</b> Major oxide concentrations of groundmass of lavas of Taranaki, measured through defocussed EPMA beam. Average of 30 spot analyses used. <b>SD7:</b> Modal proportions of mineral phases, groundmass, and vesicles of lavas of Taranaki. <b>SD8:</b> Accuracy and precision for all analyses.

补充数据:SD1:样品来源、地层单元、采样位置、形成年代、TAS标识符及类型。SD2:本研究中塔拉纳基火山熔岩的主量氧化物组成、烧失量(weight loss on ignition,LOI)、次要元素与微量元素浓度。SD3:文献报道的塔拉纳基样品主量氧化物浓度(Price等,1992、1999;Stewart等,1996;R. B. Stewart 私人通信,2018;Zernack等,2012)。SD4:文献报道的塔拉纳基样品次要与微量元素浓度(Price等,1992、1999;Stewart等,1996;R. B. Stewart 私人通信,2018;Zernack等,2012)。SD5:本研究中矿物晶体的电子探针显微分析(Electron Probe Micro-Analysis,EPMA)定点分析数据。SD6:通过散焦电子探针束测试得到的塔拉纳基火山熔岩基质的主量氧化物浓度,所用数据为30次定点分析的平均值。SD7:塔拉纳基火山熔岩的矿物相、基质与气孔的体积分数占比。SD8:所有分析测试的准确度与精密度。
