摘　　要：根据水系沉积物异常产出地质背景、矿产地质特征及各类异常查证,阐述了督冷沟铜钴矿的发现过程。依据督冷沟铜、钴矿水系沉积物异常特征,提出大面积、低浓度分带异常评价应引起重视,并进一步提出对该类异常评价的思路。Based on the geological background of stream sediment anomalies, geological features of ore deposits and evaluation of different kinds of anomalies, this paper introduced the discovery process of the Dulanggou deposit. Aiming at the characteristics of stream sediment anomalies in the Dulanggou CuCo deposit, the authors put the focus on the importance of evaluation of big area, lowconcentration zoning anomalies, and propose a new method and new thinking path for such anomalies during regional geochemical exploration.
