Abstract The Xiaobinggou lead-zinc mining area is located in the Qilian cold landscape zone. With the R-model factor analysis method and parameter statistics based on data of 1：10 000 debris survey, the authors revealed the element assemblages in the study area, and delineated the single element anomalies and the comprehensive anomalies. Through the first-level anomaly inspection in the three sifted comprehensive anomaly areas which consists of geophysical exploration method, 1：10 000 field geological mapping and different degrees of trenching and adit exploration as well as drilling, the authors outlined the ideal ore bodies and achieved breakthrough in prospecting. Debris geochemical survey has been relatively rarely employed in this region, but the success of this method in guiding the prospecting work has proved its high efficiency in the Xiaobinggou lead-zinc mining area. So, debris geochemical survey can provide a reference for ore-prospecting work in the same sort of geochemical landscape areas.
