| 中文摘要: |
| 马鬃山公婆泉东金矿地球化学景观属于甘肃北山干旱荒漠戈壁残山区，通过1:1万土壤测量，笔者利用地质和数学分析方法，对成矿及伴生元素组合特征进行了分析，并圈定了单元素异常和综合异常。对成矿前景较好的3处综合异常，采用1:1000地化剖面、1:2000地质草测、槽探、钻探等手段进行了查证，新发现金矿（化）体多条，实现了找矿突破。充分证实土壤测量在甘肃北山干旱荒漠戈壁残山区进行地质找矿的有效性，为该区地质找矿提供了新的途径。 |
| 英文摘要: |
| In geochemical landscape, the Gongpoquan gold deposit at Mazonghshan belongs to the arid desert Gobi relict mountainous area in Beishan, Gansu Province. With geological and mathematical analysis based on the data of 1:10000 geochemical soil survey, the authors analyzed the combination features of metallogenic and associated elements, and delineated the single element anomalies and the comprehensive anomalies. Through the method of the 1:1000 geochemical profile, 1:2000 geological sketch survey, trenching, drilling and so on, the authors discovered new gold ore bodies and achieved breakthrough in prospecting. The analysis of geochemical anomaly features and its exploration effects demonstrates that geochemical soil survey is effective in the Beishan, Gansu arid desert Gobi relict mountainous area, and provides a new way for the geological prospecting in this area. |
