S2: Origin and tectono-metamorphic history of the Riffelberg–Garten meta-sedimentary ophiolitic unit, Western Alps

Table S2: summary of the composition of amphibole (Amp), pyroxene (Px), garnet (Grt), phengite (Phe), paragonite (Pg), epidote (Ep), and chloritoid (Cld) in the RGU matrix. Amphibole formula on the basis of 23 O atoms, pyroxene formula on the basis of 6 O atoms, garnet formula on the basis of 12 O atoms, white mica formula on the basis of 11 O atoms, epidote formula on the basis of 12.5 O atoms, and chloritoid formula on the basis of 12 O atoms. The first line reports the average and standard deviation and the second line reports the minimum and maximum value of atoms per formula unit (a.p.f.u.). Fe³⁺ is calculated on the basis of charge balance. “n” is the number of analyses

表S2：RGU基质中角闪石（Amphibole, Amp）、辉石（Pyroxene, Px）、石榴子石（Garnet, Grt）、多硅白云母（Phengite, Phe）、钠云母（Paragonite, Pg）、绿帘石（Epidote, Ep）与硬绿泥石（Chloritoid, Cld）的组成概要。本数据集的化学式计算采用如下基准：角闪石以23个氧原子为基准，辉石以6个氧原子为基准，石榴子石以12个氧原子为基准，白云母以11个氧原子为基准，绿帘石以12.5个氧原子为基准，硬绿泥石以12个氧原子为基准。首行报告每化学式单位（atoms per formula unit, a.p.f.u.）的原子数平均值与标准偏差，次行报告其最小值与最大值。三价铁（Fe³+）通过电荷平衡法计算得出。“n”表示分析次数。
