Abstract

The method of soil geochemical survey can achieve clear prospecting,narrow the scope of prospecting,and determine the target area of prospecting.Through the soil geochemical survey in Iquique HN mining area,we finally found 9 integrated anomaly areas, including 4 anomaly areas mainly with copper,3 anomaly areas primarily with gold,2 anomaly areas mainly with zinc and molybdenum,respectively.The mining area within main abnormal was controlled by F1 fracture.Gold anomaly region with the distribution pattern of “satellite” was primarily located out of the copper(molybdenum) anomaly area. In addition, the mining area was similar to the horizontal zonal characteristics of porphyry copper deposits on the whole, and the abnormal horizontal zonal presented the order of Cu (Mo)-Au-(Zn-Pb-Ag) from inside to outside.Moreover,the anomalies showed that the area has the great potential of finding vein and porphyry copper deposits.Some of anomaly areas especially for gold anomaly region with high intensity exhibited that the gold deposit may exist, therefore,the evaluation of gold can’t be ignored during the work.
