Glow discharge mass spectrometry (GD-MS) was applied to study the nephrite minerals formed by different metallogenic mechanisms and geological environments from deposits in China, Canada, New Zealand and Russia. The GD-MS analysis and multivariate statistic analysis results indicated that two types of nephrite minerals of different metallogenic mechanisms could be classified by some typical elements. It was shown that serpentine-related nephrite minerals had higher concentrations of Cr, Co and Ni than dolomitic-marble-related nephrite minerals. Meanwhile, nephrite samples from Wenchuan had higher concentrations of Mn, V than other deposits and nephrite samples from Xiaomeiling had higher concentrations of Sr, K and Na than other deposits, which were consistent with their geological environments. These analytical results of nephrite samples by GD-MS showed that both metallogenic mechanisms and geological environments could affect the elemental concentrations in nephrite minerals.
