摘　　要：太平沟水系沉积物异常是运用森林沼泽景观区区域化探工作新方法圈定的异常,经三级查证后认为是矿致异常且找矿前景较好。在后续的勘查中发现了中型斑岩钼矿,充分体现了区域化探信息的找矿先导作用和森林沼泽景观区区域化探工作新方法的有效性。对太平沟地球化学场的展布特征进行了研究,运用优选剩余异常法提取异常信息,分析了异常特征,探讨找矿方向。The Taipinggou stream sediment anomaly was delineated by the new regional geochemical exploration method for forest- swamp landscape region. Three-grade verification showed that it is an ore-related anomaly with good ore-prospecting vista. A medium- size porphyry molybdenite deposit was discovered in successive exploration, which fully shows the ore-prospecting guiding role of the regional geochemical information and the effectiveness of the new regional geoehemical exploration method for forest-swamp landscape region. The authors conducted a study of the distribution of the Taipinggou geochemical field, extracted anomaly information by using optimum residual anomaly method, analyzed anomaly characteristics, and investigated ore-prospecting orientation.
