Structural primary halo characteristics of Qianhe Gold Deposit in western Henan and its indication for deep prospecting
Qianhe Gold Deposit in western Henan is a typical tectonic altered rock type gold deposit,and the ore body is controlled by the near EW trending tectonic belt.The study of tectonics shows that the area has undergone multi-stage evolution,forming 3 structures in the direction of near EW,NE,and SN,and different structures play a controlling or destructive role in the ore body.The F4 fault is a typical representative of the near EW structure,which is the ore-hosting structure of No.IV ore belt.Through the analysis of structural primary halo in No.IV ore belt,it is considered that the head halo elements are mainly anomalous in the middle and inner zones,and the near-ore halo elements are mainly anomalous in the inner zone.The distribution of tail halo elements is quite different,which may be related to the great variation of element mutation coefficient.The deep part of Exploration Line 83 in Level 00 of Shengou ore section and the deep part of Exploration Line 43-Exploration Line 45 in Level 260 of Shijialing ore sec-tion have good prospecting prospects.
