【 摘 要 】

Dr. W. Wei, at UCSD, provided our laboratory with chips from a suspected iron meteorite. The mass (>10 kg) was found approximately 8 northwest of Zhongshan in Guangxi province by a farmer in his fields. This mass has now been identified as an IAB iron meteorite (provisional name Zhongshan no. 1) based on its composition, N signature, and petrographic analysis. A second chip from a much larger mass (Zhongshan no. 2), still in the ground, was recently made available and work is in progress on it, but not reported. Elemental Composition: A 65 mg sample of Zhongshan no. 1 was analyzed by INAA at the Max Planck Institute in Mainz. The concentration of diagnostic elements for iron meteorites, such as Ni, Ga, Ge, and platinum group metals, are consistent with the IAB/IIICD group.
