Biotite Chemistry for Casino Porphyry Deposit in Yukon

Biotites from hydrothermal alteration zones at the Casino deposit have a distinct chemical composition compared to unaltered rocks. Their XMg values correlate positively with Ti, F, Cl, Si and negatively with Al, Fe, Mn, Ba. This dataset from the Government of Yukon may aid in understanding fluid chemistry evolution and identifying alteration zones.

Use Cases

• Identifying alteration zones based on biotite XMg and XF/XOH values.
• Analyzing fluid chemistry evolution using correlations between Ti, F, Cl, Si, Al, Fe, Mn, and Ba.
• Comparing mineral chemistry between potassic, phyllic, and propylitic alteration zones.
• Developing geochemical proxies for porphyry copper exploration in the Dawson Range.

Strengths

• Data describes distinct chemical compositions for biotites from three alteration zones.
• Correlations between multiple elemental ratios (XMg, XF/XOH, XMg/XFe) are documented.
• Dataset is published by the Government of Yukon under an open license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single Casino deposit.
