激电类方法在金属找矿中的应用
|
摘要
通过对宁夏中卫市卫宁北山地区某矿区时间域和频率域激电应用效果分析研究,发现采用三极装置具有较高的测量效率,依据反演和钻孔等资料总结出时间域和频率域方法各自优缺点,以便在实际工作中根据具体需求选择适合的测量方法。最后,在激电异常位置布设钻探,验证该地区有铜、铅、钴等矿化体显示,说明这2种方法均能反映地层,且地质效果明显。
By analyzing the application effect of time domain and frequency domain in a mining area in Beishan area,Weining,Zhongwei city,Ningxia,it is found that the three-pole device has higher measuring efficiency.The advantages and disadvantages of time domain and frequency domain methods are summarized based on inversion and drilling data,to select suitable measurement methods according to specific requirements in practical work.Finally,drilling is conducted in the anomaly location to verify the presence of copper,lead,cobalt and other mineralized bodies in the area,indicating that these two methods can reflect the strata with obvious geological effects.
