Tectonic evolution of the Proto-Tethys in the early Devonian: insights from the turbidite in the North Qilian belt, NW China

S1 analytical method Whole‒rock major and trace element and U‒Pb dating analytical methods.
S2 Table 1 U‒Pb ages of zircons from the Jiayuguan mélange turbiditic sedimentary rocks in the Hexi Corridor, North Qilian belt. Highly discordant analyses (< 90% or > 110%) are considered unusable and are displayed in strikethrough text; they are not included in the concordia diagrams. Concordant % = 100*(207Pb/206Pb) age/(206Pb/238U) age for age >1500 Ma, or 100*(207Pb/235U) age/(206Pb/238U) age for age <1500 Ma.

S1 分析方法：整体岩石主要元素及微量元素分析，以及铀-铅同位素年代测定方法。
S2 表1：北祁连带河西走廊嘉峪关混杂岩浊积岩中锆石的铀-铅同位素年龄。高度不一致的分析（<90%或>110%）被视为不可用，并以删除线形式展示；这些分析结果不包括在等时线上。一致性百分比定义为年龄大于1500 Ma时，(207Pb/206Pb)年龄/(206Pb/238U)年龄的100倍，或年龄小于1500 Ma时，(207Pb/235U)年龄/(206Pb/238U)年龄的100倍。
