根据“河南省1∶20万航磁平面图”，在灵宝-卢氏一带，绝大部分异常为磁铁矿引起，只有花木营-对沟一带航磁异常成因未查清。笔者于2011年参与了该区铁矿预查工作，通过地面高精度磁法测量，在预查区内发现磁异常一处，与1∶20万航磁异常基本吻合。通过钻孔验证，在孔深419.34～479.77 m 发现厚约60 m 的磁铁矿石英正长岩-闪长岩岩混合岩层，岩石弱磁性；通过磁测井，未发现井旁和井底盲矿。初步推断，该区的磁异常为矿区深部上述岩浆岩层（脉）引起，并对本次工作进行了总结和分析。

based on 1:200000 Aeromagnetic map of Henan Province, most anomalies are caused by magnetite, but only the reason of anomalies in Huamuying-Duigou is not proved. The author engaged in pre-survey of iron mine in this area, and by ground level magnetic measurement, an anomaly was found, basically identical with 1∶200000 Aeromagnetic map of Henan Province. Through drilling verification, magnetic iron ore quartz-syenite-diorite mixing layers of 60m long are found in 419.34~479.77 m deep. No hidden ore body is found by magnetic logging. This paper infers the anomalies are caused by deep magmatic rock (dyke), and analyzes and summarizes this work.
