Corrigendum

Corrigendum | Original article

Correction to: Geochemical Perspectives Letters 8, 26–30, doi: 10.7185/geochemlet.1825cor, published on 1 October 2018.

The authors regret that several typographic errors were included within Table S-2 in the Supplementary Information. This resulted in some of the concentrations being reported to the wrong order of magnitude. Furthermore, in Figure 2 there were one too many NBRS samples plotted, whilst sample NBCN-7 was absent from Figure 2 and Figure S-5.

We have corrected these errors and the correct versions of Figure 2, Figure S-5 and Table S-2 are shown below.

Figure 2 3He/4He vs. 4He concentrations from crushing and laser heating (open symbols) of Nyurbinskaya diamonds. 3He/4He from the cubic diamonds are higher than the cloudy and coated diamonds and plot above MORB values suggesting the diamond-hosted inclusions contain a mixture of lithospheric and deep mantle volatiles. Uncertainties shown are 1σ and for 4He concentrations are smaller than symbol size.


Figure S-5 3He/4He vs. 20Ne/22Ne for Nyurbinskaya diamonds. The diamonds show a relationship between He and Ne and trend from air towards the value of the Siberian flood basalts (Basu et al., 1995). There is potentially a third component present from the SCLM (having lower 3He/4He composition) that causes the mixing line to be shallower (R = 5) than generally expected for mixing between air and mantle alone (R = 100). Data for Udachnaya xenoliths are shown for reference indicating they contain a greater proportion of radiogenic 4He from the SCLM relative to the Nyurbinskaya diamonds (Sumino et al., 2006). Reference data for SCLM, MORB and OIB are from Gautheron and Moreira (2002); Graham (2002) and Stuart et al. (2003), respectively.


Table S-2 Helium and Neon concentration and isotopic ratios from crushing and laser extraction (italics) from the Nyurbinskaya diamonds. Diamond NBCB-9, was not successfully crushed and the complete diamond was analysed by laser extraction for noble gases. All uncertainties are reported to 1σ. n.d = not determined.
