摘　　要：通过对新疆青河县贝勒克勒铁矿高精度磁法勘探资料的分析和研究,工作区可划分为西部、北部高磁异常区、中西部负值异常区、中部面积正负磁场平缓变化区、东部跳跃变化正值磁异常区,结合工作区岩矿石标本磁性参数可判别各类磁场类型形成的地质原因。划分局部磁异常6个,其中M1、M2、M3磁异常与地下隐伏含磁铁矿石英岩有关,M4、M5、M6磁异常与含铁石英岩有关。对局部典型异常M1、M4进行了半定量解释,并进行了钻探验证,实际验证结果与推断结果较为吻合。Through the analysis and research of high precision magnetic survey data of Bel-ler Keller iron ore in Qinghe county of Xinjiang, the work area can be divided into high magnetic anomaly zone in the west and north, negative anomaly area in the midwest, the gentle change of positive and negtive magnetic field in the central area and the jumping change of positive magnetic anomaly field in the east. The geological causes of various mag-netic field formation can be distinguished with the combination of magnetic parameters of rock and ore sample in the work area. There are 6 local magnetic anomalies,of which M1, M2 and M3 magnetic anomalies are related to the underground hidden magnetite ore rocks and M4, M5, M6 magnetic anomalies are related to iron bearing quartzite. The M1 and M4 of local typical anomalies are semi-quantitatively interpreted and verified by drilling and the actual verification results are in good agreement with the inferred results.
