Two natural olivine reference materials, AOL and POL, are reported for in situ oxygen isotopic analysis. The dataset includes recommended δ¹⁸O values and homogeneity data, with a two-standard deviation of 0.33‰ (N = 105) for AOL and 0.37‰ (N = 105) for POL.

Use Cases
- Calibrating SIMS instruments for oxygen isotope analysis based on the reported matrix-matched reference materials.
- Assessing instrumental mass fractionation in olivine samples using the provided δ¹⁸O values.
- Studying mantle processes or igneous differentiation by comparing sample data to the homogeneous reference compositions.
- Validating the absence of significant matrix effects within the forsterite content range of Fo₉₁ to Fo₉₇.
Strengths
- Includes specific homogeneity metrics: two-standard deviation of 0.33‰ for AOL and 0.37‰ for POL, each based on 105 measurements.
- Provides recommended δ¹⁸O values with uncertainty ranges: 5.52 ± 0.25‰ for AOL and 5.64 ± 0.13‰ (all ± 2SD, N = 5).
- Data supports the conclusion of no significant matrix effects within a defined forsterite content range (Fo₉₁ to Fo₉₇).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The dataset is a 44.7 KB Excel file, indicating a very limited scope.
