Description
Accelerator mass spectrometry analysis of 26Al concentration in small split (#9, ~1.5 mg) of "stone of interest" (SOI) OREX-800023-0. The sample was dissolved in HF/HNO3 and a small aliquot of the dissolved sample was taken for chemical analysis by ICP-OES, while the remaining solution was processed for radionuclide analysis at Purdue University. The 26Al concentration of ~21 dpm/kg in the sample is identical to the 26Al concentration in two aggregate samples, indicating similar CRE histories in the last 1-2 Myr.
