| 摘 要： | 本文利用河北省1:20万化探扫面数据,以2.4ng/g为Au元素异常下限值,圈出了分布于冀北的3个金地球化学块体.选取矿产研究和开发程度均较高的两个块体和1个区域异常,计算得出河北省金矿的成矿率为0.45%.在此基础上,估算了勘查程度较低的地球化学块体及全省金异常区内的潜在资源量.得出全省Au的潜在资源量为1836.3 t,其中勘查程度较低的2号地球化学块体内潜在资源量占到该块体资源总量的3.8%,为河北省金矿下一步的重点勘探区域. |

| 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 ar... |
