甘肃省银元素地球化学分布由北向南 ,从低背景向中、高背景过渡 ,局部形成宏观异常带 ,银元素平均值也有北低南高的趋势。　　通过对全省大量区域化探资料的分析解剖 ,初步总结出不同地质构造背景中银的成矿地球化学条件。分布于关家沟复背斜西段的银异常带及分布于白龙江复背斜中的银异常带是我省重要的金、银富集的地球化学块体 ,具有潜在的可观的资源量 ,应作为省内银矿勘查工作的突破口。 The elemental geochemical distribution of silver in Gansu Province changes from north to south, from low background to middle and high background, and locally forms macro anomalous zone. The average silver element also has the trend of north and south high. Through the analysis and analysis of a large amount of regional geochemical data in the whole province, the author initially summarizes the geochemical conditions of silver in different geological tectonic settings. The anomalous silver anomaly belt distributed in the western segment of the Guanjiagou anticline and the silver anomalous belt distributed in the Bailongjiang anticlock anticline are important gold and silver enrichment geochemical blocks in the province with potential and considerable resources. Should be used as a breakthrough in the province of silver exploration work.
