Aerobic respiration controls on shale weathering, Geochimica et Cosmochimica Acta, 2023: Dataset

This data package was generated in order to support the development of a deep-time weathering model and to assess the coupling between shale weathering and aerobic respiration in the paper “Aerobic respiration controls on shale weathering” by Stolze et al., Geochimica et Cosmochimica Acta (2023). The package contains two csv files providing the average CO2(g) concentration profiles [ppm] and mineral concentration profiles [wt%], respectively. The CO2(g) concentration profiles were measured in the vicinity of the monitoring well PLM2 between January 2018 and April 2019. The gas samples were collected in the unsaturated zone to a depth of 1.52 m. The mineral concentration profiles were determined by X-Ray diffraction (XRD). The XRD measurements were performed on sub-core samples collected in the monitoring well PLM3 down to a depth of 7.01 m. The dataset additionally includes a file-level metadata (flmd.csv) file that lists each file contained in the dataset with associated metadata; and a data dictionary (dd.csv) file that contains column/row headers used throughout the files along with a definition, units, and data type.Update on 2024-05-28: Revised versions of the CSV data files (CO2_data_GCA_Stolze_et_al_2023.csv and XRD_data_GCA_Stolze_et_al_2023.csv) were made to apply ESS-DIVE's CSV reporting format guidelines. Updated versions of the File Level Metadata (v2_20240528_flmd.csv) and Data Dictionary (v2_20240528_dd.csv) files were updated to reflect the changes made to the CSV files.

本数据集旨在支撑深时风化模型的研发工作，并用于评估斯托尔策（Stolze）等人2023年发表于《地球化学与宇宙化学学报》（Geochimica et Cosmochimica Acta）的论文《有氧呼吸调控页岩风化》（Aerobic respiration controls on shale weathering）中，页岩风化与有氧呼吸之间的耦合关系。本数据包包含两份CSV文件，分别提供平均CO₂(g)浓度剖面（单位：ppm）与矿物浓度剖面（单位：wt%）。其中CO₂(g)浓度剖面的监测数据采集于PLM2监测井周边区域，采样时段为2018年1月至2019年4月，气体样品采自非饱和带，最大采样深度达1.52米。矿物浓度剖面通过X射线衍射（X-Ray diffraction，XRD）测定，本次XRD测试的岩心亚样品采集自PLM3监测井，采样深度达7.01米。本数据集还包含一份文件级元数据文件（flmd.csv），用于列明数据集内所有文件及其关联元数据；另附一份数据字典文件（dd.csv），收录了各文件中统一使用的列/行表头信息，并附带对应的定义、单位与数据类型。2024年5月28日更新说明：已针对两份CSV数据文件（CO2_data_GCA_Stolze_et_al_2023.csv与XRD_data_GCA_Stolze_et_al_2023.csv）推出修订版，以符合ESS-DIVE的CSV报告格式规范。同时更新了文件级元数据文件（v2_20240528_flmd.csv）与数据字典文件（v2_20240528_dd.csv），以匹配CSV文件的修改内容。
