本文介绍一个盆地在已经进行了重磁力普查,并有个别钻井成果的条件下,预测其基岩埋深的一种有效而又比较精确的方法.文中较详细地介绍了公式的理论推导、资料处理及成果的编释.研究工作是1978年在黑龙江省三江盆地东部进行的.是采用1:20万磁测资料及部分航磁资料,在 DJS—6电子计算机上演算的.

The depth of the basement beneath the eastern part of the Three-river(Heilong Jiang,Songhua Jiang,Wusuli Jiang)basin is studied using the method of analytic continuaton on the basis of 1:200,000 magnetic and par-tially aeromagnetic data.Seismic measement and drilling data demonstrated that the method used is effective and relatively accurate.The theoretical deduction of formulae,data processing and result com-piling are described in a more detaited way.Finally,the accuracy of this method is also discussed.
