Quantitative prediction and evaluation of gold resources in Chifeng

Abstract：The paper summarizes the metallogenic characteristics in Chifeng. Under the guidance of the theory of mineralization caused by geological anomalies, the authors extracted ore search information from geological, geophysical, geochemical and remote sensing data in Chifeng using the GIS technique and carried out metallogenic prediction using the weight of evidence method. On that basis, Qibov's law was adopted to estimate the gold resources. The results show that there are three NE-striking favorable metallogenic belts in the north of Chifeng, one NW-striking favorable metallogenic belt in the Tuchengzi Township-Jinchanggouliang Township in the south and three good ore prospect areas at peripheries of Laofu Township, in Harqin Qi and Balihan Township. The total gold resources are～181 tons. When 76 tons of identified is subtracted, there are still 105 tons of potential gold resources in Chifeng.
