对新近陨落的武安和老城镇陨石进行了岩石学和矿物学研究,测定了稀有气体的浓度和宇宙线暴露年龄。对武安陨石进行了微量元素的仪器中子活化分析。在上述研究基础上,确定武安和老城镇陨石分别为H_5和H_6型普通球粒陨石。
Petrology and mineralogy were carried out on the newly fallen Wu’an and the metropolitan meteorites. The concentration of rare gas and age of cosmic ray exposure were measured. The trace element neutron activation analysis of Wu’an meteorite was carried out. Based on the above studies, it is confirmed that the meteorites in Wu’an and the old towns are H_5 and H_6 ordinary chondrules, respectively.
