摘　　要：安徽宿州栏杆地区含金刚石的岩体是通过验证地磁异常而发现的。该地区钻孔资料显示含金刚石岩体均为基性辉绿岩,但含矿层与磁异常并非完全一一对应。文章结合钻孔与磁测资料就含金刚石岩体与磁异常的关系进行了分析,认为通过磁异常找矿是该区寻找金刚石的有效途径,但同时应注意对非磁性含金刚石岩体的研究。The diamond-bearing rock mass was found through the verification of geomagnetic anomaly in the Langan area,Suzhou,Anhui,and the magnetic logging of the borehole showed that the ore-bearing bed was not in exact correspondence to the magnetic anomaly,and the diamond-bearing rock mass was all basic diabase,so it is an effective method to search diamond through magnetic anomaly,but attention should also be paid to the non-magnetic diamond-bearing rock mass.
