Data Content: This dataset summarizes the behavioral characteristics of metal stable isotopes (including zinc, chromium, iron, copper, etc.) during volatile cycling in subduction zones.
Data Source: Isotope Laboratory, China University of Geosciences (Beijing).
Data Processing Method: Qualified data were systematically collected from peer-reviewed published literature, while partial copper and zinc data were sourced from historical test data of this laboratory. The processing workflow involves chemically purifying the selected samples prior to data acquisition using Multi-collector Inductively Coupled Plasma Mass Spectrometry (MC-ICPMS).
Data Quality: All data underwent rigorous inspection to ensure reliability and accurate reflection of the scientific questions before being compiled into figures. The experimental data are summarized qualitatively in the figures.
Application Prospects: The volatile cycle in subduction zones not only profoundly impacts the interactions between Earth's various spheres, but also plays a critical role in key geological and environmental processes such as the migration and enrichment of metallogenic metal elements and global climate change. In recent years, tracing subduction zone volatile cycles using metal stable isotopes has garnered widespread attention and achieved remarkable progress; however, most studies remain limited to conducting tracer research on specific metal isotopes for individual volatile elements. Based on the geochemical property differences of various metal elements and their binding forms with multiple volatiles, this work systematically summarizes the characteristics of metal stable isotopes in tracing different volatile cycles in subduction zones. Generally, magnesium and zinc isotope systems are the most effective for tracing the subduction zone carbon cycle; metal isotope systems such as lithium, magnesium, potassium, barium, and molybdenum each have unique advantages in tracing subduction zone water (fluid) cycles; zinc isotope exhibits significant potential for tracing the subduction zone sulfur cycle; chromium isotope has a unique advantage in tracing the subduction zone chlorine cycle; variable-valence metal isotope systems including iron, chromium, and copper are highly sensitive to the redox state of volatiles, making them promising tools for tracing the subduction zone oxygen cycle. These isotope systems provide a novel perspective for understanding the volatile cycle in subduction zones, and will serve as an important research direction in future Earth system science.
