动力三角翼航磁在多宝山矿区的应用效果

摘要

In order to explore the rapid ways of prospecting the minerals in the forest-swamp area, the dynamic delta wing aeromagnetic was applicated in the Duobaoshan ore district which located in Heilongjiang province. In the comparision of the conventional aeromagnetic and geomagnetic methods, this paper shows the accuracy and superiority of the dynamic delta wing aeromagnetic. Based on the characteristics of aeromagnetic and the analysis of key copper deposits, it summarizes the abnormal phenomena of porphyry copper deposit, which confirms the validity of the dynamic delta wing aeromagnetic in prospecting the porphyry copper deposits.%为了探索森林沼泽覆盖区快速找矿评价方法,在黑龙江省多宝山矿区进行了1:1万动力三角翼航磁勘查应用.通过与常规航磁、地磁方法的应用效果对比,说明动力三角翼航磁的准确性和优越性.根据多宝山矿区航磁特征及重点铜矿床的分析结果,总结出斑岩型铜矿磁异常的规律,可以认为动力三角翼航磁可用于斑岩型铜矿的间接找矿.
