| [摘要]我国西部找矿潜力巨大,但复杂的地质构造演化过程和特殊的地貌景观条件,严重制约
着找矿效率和效果。双频激电法以其自身具有的轻便灵活、观测精度高等优点,在西部特殊地貌区金属
矿预测中能够发挥独特的作用。本文简要介绍了双频道激电法的原理和SQ-3c 双频道激电仪的特点,
研究分析了该方法在西部两类典型覆盖区(云南高山植被覆盖区和新疆荒漠戈壁覆盖区) 的应用效果;
讨论了双频道激电法在工作设计、野外实践中遇到的装置和工作频率选择、接地电阻改善、测量出现负
值等问题,及避免这些问题的方法技术。 |

| Abstract:There are great potential in metal deposit production in Western China. At the same time, the efficiency and effect of deposit production
are restricted severely because of complicated evolution of geological structure and special landscape. Dual-frequency IP method has many advantages and
it is very suitable for metal deposit production of special landscape in Western China. In this paper, the theory of this method is introduced and then the
effect of this method in typical overburden areas ( alpine vegetation overburden areas in Yunnan Province and Gobi desert overburden areas in Xinjiang
Province) in Western China is studied. Finally, some problems in field works are discussed. These problems include choosing of array and work frequen鄄
cy, reducing of grounding resistance etc. |
