Extended Data Table 1 Reproducible 3He/4He crushing results

From: Highest terrestrial 3He/4He credibly from the core

  1. Twelve samples have 3He/4He values that overlap within 1 SD analytical uncertainty. The reported means for these samples are inverse-variance weighted and assigned weighted standard errors. Due to possible radiogenic 4He contributions, these results should be viewed as minimum magmatic ratios. See Supplementary Table 1 for complete He results.
