| 摘 要： | 本文采用堆中子和超硼中子活化方法对Mundrabilla、浙江宁波、湖北黄陵、河北商都、广西南丹、贵州董岭、四川乐山、广西邕宁、新疆准噶尔等九个铁陨石和吉林陨石的金属颗粒作了分析,测定了Ge,Ga,Ir,Ni,Au,As,Cu和Co等八个元素的含量。并对九个铁陨石作了化学群的分类,它们分别属于ⅠAB,ⅢAB,ⅢCD和IVA群。南丹和董岭铁陨石的化学组成极为相似,它们可能是“成对”的铁陨石。

| Abstract: | Contents of Ge,Ga,Ir,Ni,Au,As,Cu,Co,in nine pieces of iron meteorites,Mundrabilla, Ningbo,Huangling,Shangdou,Nandan,Dongling,Leshan,Yongning,Zhungeer and two metallic samples of Jilin meteorite have been determined with Instrumental Neutron Activation method.Pile and epiboron neutron activation were used in analyses."We have classified 9 iron meteorites.Nine are normal members of the groups IAB,IIIAB,IIICD,and IVA.The composition of Dongling is very similar to Nandan,it seems probable that they are paired. |
