抚顺地区低缓磁异常及找矿方向探讨

Weak and gentle magnetic anomalies and prospecting direction in Fushun area

本文从区域地质背景以及航磁异常特征方面入手,对大东洲中型铁矿床从地质条件、航磁特征以及地面磁异常规模等方面进行了研究,总结了抚顺地区低缓磁异常的形态规模、地质特征等方面的标志,并对都督村低缓航磁异常进行了分析,指出具航磁异常的盖层分布地区是寻找隐伏铁矿体的有利部位。

In this paper,starting from the characteristics of the regional geological setting and aeromagnetic anomalies,geological conditions,characteristics of aeromagnetic and ground magnetic anomaly scale of Dadongzhou medium-sized iron deposit are studied,the signs of morphology and scale,geological features of weak and gentle magnetic anomalies in Fushun region are summarized,and weak and gentle aeromagnetic anomalies of Dudu village were analyzed.It is pointed out that the caprock distribution area with aeromagnetic anomaly is the favorable position for finding the concealed iron ore body.
