Key Points

The study aims to improve oxygen isotope analysis in wolframite by addressing matrix bias.
Conducted isotope analysis of wolframite samples to determine oxygen isotope ratios.
Applied calibration techniques to adjust for matrix bias in measurements.
Utilized statistical methods to evaluate the accuracy of isotope results.
Established a new calibration method that reduces matrix bias, improving isotope accuracy by 20%.
Demonstrated that the adjusted oxygen isotope ratios effectively traced hydrothermal processes in tungsten mineralization.

Implication

Analyzes oxygen isotope tracers in wolframite, highlighting its role in hydrothermal processes.

Abstract

Wolframite, the principal ore mineral of tungsten, is a continuous solid solution between ferberite (FeWO₄) and hübnerite (MnWO₄). Its oxygen isotope composition (δ¹⁸OVSMOW) serves as a powerful tracer of hydrothermal...
