马鞭山铁矿处于庐枞火山岩盆地北部边缘，其赋矿层位为东马鞍山（T2d）含铁质、钙质泥质粉砂岩。航磁为梯度带上叠加局部异常、局部异常形态规则，其走向与梯度带大致平行；地磁与航磁对应较好，异常未分解；地磁异常剖面曲线连续完整且正负伴生、具低缓特征。小波变换较好地分离出了矿致异常。盆地西侧和北侧二条航磁梯度带上局部低缓磁异常系寻找该类铁矿的重要指示信息。
馬鞭山鐵礦處于廬樅火山巖盆地北部邊緣，其賦礦層位為東馬鞍山（T2d）含鐵質、鈣質泥質粉砂巖。航磁為梯度帶上疊加跼部異常、跼部異常形態規則，其走嚮與梯度帶大緻平行；地磁與航磁對應較好，異常未分解；地磁異常剖麵麯線連續完整且正負伴生、具低緩特徵。小波變換較好地分離齣瞭礦緻異常。盆地西側和北側二條航磁梯度帶上跼部低緩磁異常繫尋找該類鐵礦的重要指示信息。

The Mabianshan iron ore deposit lies at northern fringe of the Lu-Zong volcanic basin and is hosted in the Dongmaanshan (T2d) iron-bearing and calcareous muddy siltstone. Aeromagnetic map shows that gradient zone is locally overlapped with anomaly, and the local anomaly is regular in form with its trend generally parallel to the zone. Ground magnetic and aeromagnetic features are well matched, without decomposed anomaly. Ground magnetic profile curve is continuous, complete, with pairs of negative and positive and gentle. Wavelet transformation well separates out mineralized anomaly. Local gentle magnetic anomalies on the west and north sides of the basin are important indicators for seeking this kind of iron ore deposit.
