摘　　要：大东沟—小营沟南部区己发现有数条小规模的磁铁石英岩型铁矿体。通过对测区开展高精度磁测工作,在Ⅰ号磁铁石英岩型铁矿体北东部发现规模和范围更大的磁异常带,经过定性分析和各种定量计算,结合测区地质资料,推断该异常为近直立的厚板状铁矿体引起。There has found several small magnetite quartzite type iron ore body in the southern area of Dadonggou-Xiaoyinggou. Through high precision magnetic survey in the test area, greater scale and scope magnetic anomaly zone were found in North Eastern of No.1 magnetite quartzite type ore body. Through qualitative analysis and quantitative calculation, combined with geological data of the test area, we inferred the anomaly is caused by nearly vertical tabular iron ore body.
