Application of EH4 in the II Forecast Area of Yushiwa Iron Mine of Hanxing Area, China

摘要

Yushiwa iron mine is under the administrative divisions of Xixu town of She city in Hebei Province. The authors have reached the conclusion that the iron ore bearing horizon is the middle of Ordovician limestone, magmatic rocks in this area is for acid diorite, along with invasive structural vulnerability. EH4 is widely used in solid minerals, especially in finding concealed ore deposit. In this paper, the author adopted EH-4 method to make a synthetic study on the II forecast area of Yushiwa iron deposit in Hanxing area. The result showed that the geophysical method was quite useful in the exploration of concealed ore deposit.
