陕西省白水县铁牛河岸边二级阶地黄土层中有一形似牛头的“铁块”,其来历始终不甚明确.为查明“铁块”的成因,从1986年起开始对其进行研究。通过光、薄片观察,x—射线衍射分析,化学分析及铅同位素组成研究,最后终于得到了明确的鉴定结果。该“铁块”为一古代人工铸铁,既非铁陨石,也非地球上的自然铁。
The origin of the “iron block” shaped like a bull’s head in the loess layer of the second terrace on the bank of the Tieshue River in Baishui County, Shaanxi Province, has never been clear in its origins and has been studied since 1986 in order to find out the cause of the “iron block.” Through the light, thin sheet observation, x-ray diffraction analysis, chemical analysis and lead isotope composition studies, and finally finally get a clear identification of the results. The “iron” is an ancient artificial cast iron, neither iron meteorites, nor natural iron on Earth.
