摘　　要：通过对蒙古国某地90个航空物探异常的综合研究,推断其中多个异常为矽卡岩型磁铁矿引起的异常,后经地面异常检查及工程验证,证实其中5个异常是矽卡岩型磁铁矿引起的。初步估算,5个异常区内矿石量达1亿t左右。Based on an integrated study of 90 air-borne geophysical anomalies in a certain area of Mongolia,the authors inferred that quite a few of them are caused by skarn magnetite deposits.Surface anomaly inspection and engineering verification reveal that five of these anomalies are related to magnetite deposits.A preliminary estimation shows that ore reserves in the five anomaly districts can reach a hundred million tons or so.

关 键 词：蒙古国 航磁异常 地面异常检查 矽卡岩型磁铁矿
