湖南禾库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 Heku area,Hunan Province

摘要: 依据1∶5 万水系沉积物测量资料，分析研究了湖南禾库地区水系沉积物地球化学特征。对元素分布、单元素异常、元素相关性、异常元素组合等特征的研究表明水系沉积物地球化学测量方法在高山峻岭、地形复杂的禾库地区有良好的找矿效果，并优选了嗅脑和杉木冲2处铅锌找矿远景区。

Abstract: On the basis of 1∶50000 stream sediment survey，the geochemical characteristics of the arctic-alpine zone in Heku area were tentatively analyzed. The distribution of the elements，the elements relation in single 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 two Pb-Zn-Cd-V ore-forming places.
