Abstract

Borehole TEM method is an effective method for the deep buried conductive sulfide ore, this research took three component transient electromagnetic measurement in borehole zk506 in Xinjiang Baishiquan Cu-Ni ore as an example, combined with the known information of the borehole, through the analysis of features of the curves, marked off three anomalies from top to bottom and speculated that the second was the main anomaly, determined that its azimuth was southeast, and judged that the anomaly extended far in the southeast direction according to the high amplitude of response of component z in the later period. Finally, comparison of the geological logging of borehole zk506 and later drilled boreholes zk507 and zk508 proved the inference and the interpretation of borehole TEM, revised previous geological knowledge based on the single record of the borehole zk506. The validity and the importance of borehole transient electromagnetic method in the exploration of sulfide deposits with good conductivity are testified.
- borehole TEM,
- three components measurement,
