Abstract： Based on data obtained from the Regional Geochemistry-National Reconnaissance Project (RGNR) of Hebei Province and using 2.4 ng/g as the threshold of geochemical anomaly, the authors delineated three Au geochemical blocks distributed in the northern part of Hebei Province. Statistics of these two geochemical blocks and a regional geochemical anomaly show that the gold mineralization coefficient is 0.45%. Calculation of gold resource potential based on this gold mineralization coefficient reveals that there are still 1836.3 ton (given 1000 m thickness of every rock mass) gold resources in geochemical anomalies within the province. The exploration extent of No.2 Au geochemical block is relatively low, but its estimated potential resources account for 3.8% of itself, and hence this block seems to be the most promising area in further exploration.
