Mineralogic and isotopic investigations on lunar rock 12013


Sample 12013, 10 was a sawn slab, 50 X 22 X 4 mm, cut from a position about 6 mm from an exterior surface of lunar sample 12013 returned from the Apollo 12 mission. Because of its extreme heterogeneity it was delivered to our clean-lab for division and distribution to the various principal investigators. Prior to division it was carefully examined and photographed and preliminary Rb/Sr and microprobe results were obtained on loose fragments found in the sample container. Thin section 12013, 4 (Apollo 12 sample catalog) from an unknown part of the sample also provided some guidance in the distribution.
