摘要
用土壤测量对新立屯1∶5万水系沉积物金异常进行检查,圈出3条Au、Ag、Hg、Sb、F、Pb、Sn在空间上相互重叠的多元素异常带。对地表异常的地质观测和初步的槽探揭露,发现这3条异常带基本与两条矿化蚀变带相对应,并在局部地段圈出具工业价值的Au矿体。对这些土壤异常含矿性的地球化学评价表明,新立屯工区的土壤异常主要是由盲矿体所致,推测盲矿体的埋深在100m～200m之间,预计钻孔在150m～200m孔段,可打到主矿体的中上部位。
The soil survey was carried out in the Xinlitun area to trace and evaluate the Au anomaly of the 1∶50000 stream sediment survey. The three anomaly belts of Au, Ag, Sb, F, Pb and Sn were delineated. The geological investigation and trenching engineering indicate that the three anomaly belts correspond to the two gold mineralization belts. The gold orebodies have been found.These anomalies are the reflects of concealed gold orebodies which are 100 to 200 m deep.The upper and middle part of the gold orebodies are expected to be intersected by drills at depth of 150 m to 200 m.
