Data from "The chemical classification of iron meteorites—VII. A reinvestigation of irons with Ge concentrations between 25 and 80 ppm" by Scott et al. (1973)

This dataset contains mean concentrations of Ni, Ga, Ge, and Ir in 193 iron meteorites. Nickel was analyzed by atomic absorption spectrometry (AAS), and other elements were analyzed by radiochemical neutron activation analysis (RNAA) at the University of California, Los Angeles.

本数据集包含193颗铁陨石中镍（Ni）、镓（Ga）、锗（Ge）以及铱（Ir）的平均浓度。其中镍采用原子吸收光谱法（atomic absorption spectrometry, AAS）进行分析，其余元素均由加利福尼亚大学洛杉矶分校采用放射化学中子活化分析（radiochemical neutron activation analysis, RNAA）完成检测。
