Oxygen and silicon isotope ratios of lunar rock 12013
Creators
Abstract
The δ18O and δ30Si values of six whole-rock samples from the high-SiO2 lunar rock 12013, 10 are very uniform at +5.95 to +6.34 and −0.49 to −0.07, respectively. These data are very similar to those obtained on terrestrial basalts and gabbros, the previously analyzed Apollo 11 lunar rocks, and terrestrial rhyolite obsidians from oceanic areas. Rock 12013 is, however, distinctly lower in 18O than tektites and terrestrial plutonic granitic rocks, strongly suggesting that tektites do not come from the moon.
Additional Information
We wish to thank D.A. Papanastassiou and G.J. Wasserburg for preparing the samples of rock 12013. Discussions with G.J. Wasserburg and L.T. Silver have been very valuable. This work has been supported by NASA contract NAS 9-7944.Additional details
