河北XD银矿外围水系沉积物地球化学异常特征和找矿方向浅析

AN INITIAL ANALYSIS ON THE ANOMALY CHARACTERISTICS OF STREAM SEDIMENT GEOCHEMISTRY OUTSIDE XD SILVER DEPOSIT, HEBEI AND ITS EXPLORATION DIRECTION

对 XD银矿外围水系沉积物地球化学异常特征研究表明 ,区内具有极好的寻找银(金 )多金属矿前景。认为 Ag、Pb是近程指示元素 ,Zn、As、Sb为远程指示元素 ,拆离断层及隐伏拆离断层上盘、次火山岩与长城系碎屑岩接触带的 Ag多金属异常分布区是今后找矿的重要靶区。

The research work on characteristics of stream sediment geochemical anomalies outside XD silver deposit shows that there are great potential for the exploration of Silver(Gold) polymetallic deposits around XD silver deposit. Ag and Pb is considerd as short distance indicator element while Zn, As, Sb as long distance indicator. The breaking up faults and the hanging walls of the buried breaking up faults, and Ag polymetallic anomaly distribution area along the contact between subvolcanic rocks and Changchen Series clastic rocks are important target for the coming explorations. -
