来自阿波罗12号飞行任务的五个岩石样本和一个微粒样本的硫浓度从550ppm到903ppm不等。岩石的δ34S值从+0.37‰到+0.68‰，而微粒样本的硫浓度为+8.70ppm(均相对于峡谷暗黑陨石)。δ33S和δ36S的对应值表明，所涉及的同位素效应是质量相关的，样品中存在的硫量掩盖了对33S和36S的同源贡献。
Sulphur concentrations in five rock samples and one fines sample from the Apollo 12 mission range from 550 ppm to 903 ppm.δ34Svalues for the rocks range from +0.37‰ to +0.68‰ while for the fines sample it is +8.70‰ (all with respect to Canyon Diablo troilite). The corresponding values obtained forδ33S andδ36Sshow that the isotope effects involved are mass dependent and that the amounts of sulphur present in the samples mask spallogenic contributions to33S and36S.
