Mo同位素数据库

收集的已发表文献中的关于表生过程和深部过程的Mo同位素数据组成数据库，以上数据采集地点为全球典型地质剖面、矿床等地质体。数据库要素包含样品基本信息、样品地质信息、年龄、分析物质类型、化学处理方法、主微量元素组成、以及同位素组成及误差。其中基本信息主要要素包括：样品号、位置（经纬度，地理位置描述，构造位置描述）、地质体采样位置岩体（岩浆岩）、沉积层位、钻孔信息，剖面信息等。同位素组成及误差：同位素值、误差报道、长期测试精度、分析方法、分析实验室、标样转化等。使用的仪器为多接收电感耦合等离子质谱仪(MC-ICP-MS，Neptune Plus)。数据收集时间为2020-2025年。This database is constructed using molybdenum (Mo) isotope data related to surficial and deep geological processes extracted from published literature. All data were collected from typical global geological sections, ore deposits and other geological bodies. The database includes the following types of information: basic sample information, geological context of samples, sample age, analytical material type, chemical treatment procedures, major and trace element compositions, as well as isotope compositions and their associated uncertainties. The basic sample information mainly includes: sample identification number, location (latitude and longitude, geographical description, tectonic setting description), sampled rock mass (igneous rock) at the sampling site, sedimentary horizon, drilling information, section information, etc. For isotope compositions and uncertainties, the recorded contents include: reported isotope values, uncertainty reports, long-term test precision, analytical methods, analytical laboratories, standard sample calibration, and so on. The analytical instrument employed is the multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS, Neptune Plus). The data collection period spanned from 2020 to 2025.
