摘要
在豫西南某金铜矿区采用双频激电法进行勘探,应用大比例尺中梯扫面快速圈定异常分布特征,采用激电测深装置了解极化体空间赋存状态,利用激电场频谱特征区分含石墨大理岩及金属硫化物等,并结合矿区地质条件,取得了很好的找矿效果。
Using the large-scale middle gradient sweep ladder,the authors rapidly delineated the distribution of anomalies.IP sounding device was adopted to detect space state of the polarization body,and frequency spectrum characteristics of IP field were used to distinguish graphite-bearing marble from metal sulfides.Based on comprehensive geophysical exploration in combination with geological conditions of the ore deposit,the dual-frequency IP method has achieved good results in the exploration of a gold-copper deposit in southwest Henan Province.
