Based on the analysis of different dating methods of isotopic system and the dating results of the metumorphic mafic-ultramafic rocks in Shunchang, Northern Fujian, it's proposed in the paper that the U-Pb method of single zircon and the method of the whole-rock Sm-Nd isochronic age should be taken as the main ways for dating metamorphic mafic-ultramafic rocks in the orogenic belts.
通过对不同同位素体系测年方法的分析，并结合闽北顺昌镁铁－超镁铁杂岩的系统同位素年代测定结果，提出造山带中变质镁铁－超镁铁岩的年代测定应以颗粒锆石Ｕ－Ｐｂ法和全岩Ｓｍ－Ｎｄ等时线法为主，对Ｒｂ－Ｓｒ、４０Ａｒ－３９Ａｒ和Ｋ－Ａｒ同位素测年结果的应用应持慎重态度。
