中文摘要:
      高精度磁测是利用各种岩(矿)石间磁性差异所引起的磁异常来寻找有用矿产或查明地质构造的一种地球物理勘探方法。在新疆艾勒克雀库铁矿区开展了地面高精度磁测、勘查线剖面高精度磁测与地质测量、槽探和钻探验证相结合的综合地质评价工作,依据ΔT化极磁异常特征,结合矿区地质特征和岩(矿)石物性特征,对矿区地面高精度磁测数据开展了综合研究,预测了磁铁矿体的空间位置和产状,进行槽探和钻探工程验证,圈定了8个磁铁矿体。工作成果表明,高精度磁测是新疆艾勒克雀库铁矿寻找磁铁矿体的最直接、最有效的方法之一。
英文摘要:
      High precision magnetic survey is a geophysical method of showing magnetic anomalies caused by magnetic differences of rocks (ores) and identifying ores and rocks and geological structures according to the anomalies. Ground high precision magnetic survey, high precision magnetic survey of exploration line profile, geological survey, trenching and drilling are integrated to prospect Ailekequeku Fe deposit. Based on characteristics of the ΔT reduction to pole magnetic anomaly, geological characteristics of the deposit area and the physical properties of rock (ores) of the deposit the high precision magnetic survey data of the Fe deposit are comprehensively studied then spatial location of Fe ore bodies and their occurrences predicted. The Prediction is verified by trenching and drilling with 8 magnetic Fe ore bodies located thus high precision magnetic survey is a direct and effective method to prospect magnetic Fe ore deposit.
