Geochemical Indicators for Cobalt-Rich Skarn Exploration in the Gangdese Belt

Pusangguo granodiorite data, including zircon U-Pb geochronology and Sr-Nd-Hf isotopes, supports a genetic link between adakitic intrusions and cobalt-rich skarns. The dataset, 22.3 KB in size, was authored by Zhaxi Pubu and last updated in March 2026. It aims to identify key geochemical signatures for targeting cobalt mineralization in the Gangdese metallogenic belt.

Use Cases

• Train models to classify intrusions associated with cobalt-rich skarns based on adakitic geochemical signatures.
• Analyze the correlation between high oxygen fugacity magmas and cobalt enrichment using isotopic and whole-rock chemistry data.
• Build exploration indicator systems for the Gangdese belt using features like Sr/Y and La/Yb ratios.

Strengths

• Includes multiple analytical methods: petrography, geochronology, whole-rock geochemistry, and Sr-Nd-Hf isotopes.
• Data is focused on a specific, economically significant deposit type (cobalt-rich skarns) within a defined metallogenic belt.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is very small (22.3 KB), suggesting a limited scope or sample size.
• Geographic coverage is specific to the Pusangguo deposit in the Gangdese belt.
