| Abstract: | The δ O18 and δ Si30 analyses of the Luna 20 soil sample are +6.18 and +0.22, respectively, relative to the SMOW and Rose Quartz standards. However, an anomalous δ O18 value of +8.13 was obtained on one aliquot of the Luna 20 sample. Possible reasons for this apparently erroneous result are discussed. |
