This database comprises cadmium (Cd) isotope data related to deep and surficial geological processes, compiled from peer-reviewed published literature. All data were collected from typical global geological bodies including geological sections, ore deposits and other geologic units. The database contains the following information items: basic sample information, sample geological background, age, analytical material type, chemical preparation methods, major and trace element compositions, as well as isotope compositions and their associated errors. The basic sample information mainly includes: sample number, location (covering latitude and longitude, geographic location description, tectonic setting description), sampled rock mass (igneous rock) of the geological body, sedimentary horizon, drilling information, section information, etc. For isotope compositions and errors: this includes isotope values, error reports, long-term measurement precision, analytical methods, analytical laboratories, standard reference material calibration, etc. The analytical instrument used is multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS, Neptune Plus). The data collection period was from 2020 to 2025.
