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《低角度俯冲带特提斯沉积物循环效率与机制解析：基于马克兰弧（Makran arc）火山的研究启示》的补充材料。数据集包含三张表格，收录了马克兰弧岩石的年代学及地球化学数据，以及用于评估马克兰俯冲带沉积物循环情况的碳含量数据。
补充表S1：科赫-苏丹火山（Koh-i-Sultan volcano）火山样品的40Ar/39Ar定年结果，详细分析流程见正文。
补充表S2：马克兰弧火山岩的新分析与汇编的全岩地球化学数据，涵盖主量元素、微量元素含量及Sr-Nd-Pb同位素组成，表格内标注了对应的分析测试技术。
补充表S3：马克兰海沟（Makran trench）沉积物岩芯的碳含量数据，用于估算沉积物总碳收支，进而开展循环效率评估，该数据集汇编自深海钻探计划（DSDP, Deep Sea Drilling Project）与大洋钻探计划（ODP, Ocean Drilling Program）公开资料。
本数据集以Excel格式提供。
