大兴安岭成矿带是中国最重要的有色金属成矿带之一，资源潜力巨大，但其北段是森林沼泽景观区，矿产勘查难度很大。笔者在该区以1∶20万区域化探异常为主要依据优选靶区，以土壤、岩屑地球化学测量为基本勘查方法，根据元素地球化学参数，系统、逐级地研究预查、普查、详查阶段的地球化学特征，并重点研究叠加成矿作用和不同勘查阶段的优选方法组合，新发现了上坑锅火山热液型大型铅锌矿床，建立了适合于森林沼泽覆盖区的地质-地球化学勘查模型。

The Da Hinggan Mountains metallogenic belt is one of the most important base metal mineralized zones in China. Mineral ex-ploration, however, is very difficult in the northern part because of forest and swamp cover. The authors first selected the potential tar-gets by data processing and interpretation of 1 ∶ 20 000 regional geochemical anomalies. Detailed soil survey clearly indicates that there might be some economic base ore bodies in the regional geochemical targets. The innovatory high density rock chip survey successfully defined the dimension of the mineralizations. The Shangkenguo superlarge Pb-Zn deposit was found after trenching and drilling the geo-chemical anomalies. The geochemical methods and idea resulting in successful discovery can be an example of mineral exploration in the forest and swamp landscape.
