Decoding recycling efficiency and mechanism of Tethyan sediments in a low-angle subduction zone: Insights from the Makran arc volcanoes

This dataset is the supplementary material of the submitted manuscript “Decoding recycling efficiency and mechanism of Tethyan sediments in a low-angle subduction zone: Insights from the Makran arc volcanoes”. It contains three tables that provide chronological and geochemical data of Makran arc rocks, as well as carbon content data used to evaluate sediment recycling in the Makran subduction zone. Supplementary Table S1: 40Ar/39Ar dating results for volcanic samples from the Koh-i-Sultan volcano. Detailed analytical procedures are provided in the main text. Supplementary Table S2: Newly analyzed and compiled whole-rock geochemical data for Makran arc volcanic rocks, including major and trace element concentrations as well as Sr–Nd–Pb isotopic compositions. Analytical techniques are indicated within the table. Supplementary Table S3: Carbon content data of sediment cores from the Makran trench, used to estimate the bulk sediment carbon budget for recycling efficiency assessment. These data are compiled from ODP/DSDP sources. The dataset is provided in Excel format.本数据集为投稿论文《缓俯冲带特提斯沉积物循环效率与机制解码——以马克兰弧火山为例》（Decoding recycling efficiency and mechanism of Tethyan sediments in a low-angle subduction zone: Insights from the Makran arc volcanoes）的补充材料。数据集包含三张表格，涵盖马克兰弧火山岩的年代学与地球化学数据，以及用于评估马克兰俯冲带沉积物循环的碳含量数据。 补充表S1：库赫-苏丹火山（Koh-i-Sultan volcano）的火山样品40Ar/39Ar定年结果，详细分析流程参见正文。 补充表S2：本次新分析并整理的马克兰弧火山岩全岩地球化学数据，包括主量元素、微量元素含量及Sr-Nd-Pb同位素组成，分析方法已在表内标注。 补充表S3：马克兰海沟沉积物岩芯的碳含量数据，用于估算沉积物总碳收支以开展循环效率评估，该数据集整理自大洋钻探计划（ODP, Ocean Drilling Program）与深海钻探计划（DSDP, Deep Sea Drilling Project）的公开资料。 本数据集以Excel格式提供。
