通过对甘肃北山南带金矿床（点）稳定同位素组成特征的研究及水／岩交换理论提供的找矿信息，探讨了本区金矿床（点）的物质来源具多源性，但以壳幔混合型为主；矿源层形成于华力西中晚期，而燕山期是金的主要成矿期。提出钻井沟金矿点具找矿远景，其次为拾金坡；金沟子及花西山找矿意义不大。推测乌龙泉、老君庙金矿点和小西弓金矿床中带深部应有新的水／岩交换中心和盲矿体
Based on the study of the stable isotopic compositions of gold deposits in the Beishan area of Gansu province and the ore-prospecting information provided by the water / rock exchange theory, the source of the gold deposits in this area is characterized by multiple sources. However, Mixed type; source layer formed in the middle and late Variscan, and Yanshan period is the main gold mineralization period. It is proposed that the prospecting prospect of drilling gold deposit is the point of prospecting, followed by picking gold slope; the gold ditch and Huaxishan deposit have little significance. It is speculated that there should be new water / rock exchange centers and blind ore bodies deep in the Wulongquan, Laojuimiao gold deposits and the Xiaoxibow gold deposit
