The authors applied the wide field electromagnetic method to conducting work in Mesoproterozoic carbonatite nappe area and achieved good result. It is for the first time that Beipiao source formation was discovered below the carbonatite nappe, which was further proved by well cores. It shows low resistance in comparison with things of its adjacent layers. The actual electronic resistance of underground electric body was also obtained. These discoveries have enriched the exploration strata of the east Yanliao subsiding belt and expanded one Mesoproterozoic exploration stratum to two exploration strata, i.e., the Mesoproterozoic black carbonate stratum and mudstone stratum.
