河北赤城地区水系沉积物地球化学特征及找矿预测

Geochemical Characteristics of Stream Sediments and Metallogenic Prognosis of Chicheng area,Hebei Province

依据1∶5万水系沉积物测量资料,分析研究了河北省赤城地区水系沉积物地球化学特征。对元素变化、含量、分布特征、元素相关性特征及综合异常进行研究,表明水系沉积物地球化学测量在地形复杂、群山峻岭的河北赤城地区,具有良好的找矿效果,并优选出了下窝铺-温家营银钼铅锌金多金属等七处成矿远景区。

On the basis of 1 ∶ 50000 stream sediment survey,the geochemical characteristics of the arctic-alpine zone in Chicheng area were tentatively analyzed. The distribution of the elements,the elements relation in anomaly and the features of the anomaly were also studied. The result shows that the method of geochemical stream sediment survey is obviously effective in the area of complicated topography,as evidenced by the successful delineation of seven ore-forming places.
