钕同位素分子式:CAS号:性质:自然界中钕以142Nd,143Nd,144Nd,145Nd,148Nd,149Nd,150Nd七种同位素的形式存在,相对丰度分别为27.11%, 12.17%; 23.85%, 8.30%, 17.22%, 5.73%, 5.62%, 其中143Nd由147Sm衰变产生,研究钕同位素组成时,以144Nd作比较基础,测定143Nd/144Nd比值。在地质科学中根据147Sm/144Nd-143Nd/144Nd之间的衰变关系测定较古老地质体的年龄,根据由等时线外推或已知年龄条件下反演得到的地质体形成时的初始143Nd/144Nd比值,讨论成岩成矿物质来源、地壳增长及壳幔相互作用。
