坦桑尼亚某金矿区及外围矿区均处在空旷的季节性沼泽地带内，由于受自然条件的限制，在地质（没有基岩露头）、化探（沼泽性黑土覆盖厚度大）、电法（低阻屏蔽干扰严重）等找矿方法效果均不佳的情况下，磁力测量发挥了间接寻找隐伏含铁建造型金矿床的重要作用，取得了反映地下深部与金矿床有关的含铁建造引起的良好磁力异常，为矿区和外围矿区的钻探工程布置，进一步扩大矿床规模，提供了强有力的磁测资料。
@@@@One gold mining area in Tanzania and its peripheral mine are in open seasonal swamp zone .Due to the limitations of natural conditions,geological ( no bedrock outcrop),geochemical ( the swamp black covering thick-ness),electrical (low resistive shielding serious interference ) exploration methods all worked poorly ,while magnetic measurement played an important role in search for concealed iron-containing gold deposit and reflected a deep under-ground gold related iron-containing construction causing a good magnetic anomaly which contributes strong magnetic data to commissioning the peripheral mine drilling engineering layout and to further expanding the deposit scale .
