摘要: 小西弓金矿是干旱荒漠戈壁残山景观区北山区段重要的金矿床。选择具干旱荒漠景观区典型特征的小西弓金矿床及其外围开展地球化学勘查方法技术的对比,系统研究了土壤测量和水系沉积物测量中风积物的干扰特点、测量的效果和适用性。结果表明,在小西弓金矿区及与其相似的干旱荒漠戈壁残山景观区开展地球化学勘查应首选土壤测量。

Abstract: The Xiaoxigong gold deposit is an important deposit in Beishan arid desert gobi relict mountain landscape region. A compara-tive study of geochemical exploration methods and techniques were carried out in the Xiaoxigong gold deposit and its periphery. The au-thors conducted a systematic investigation into the interference characteristics of aeolian deposits in the stream sediments and soil as well as the effectiveness and applicability of the stream sediment survey and soil survey. The results show that soil survey should be taken as the first preference in the two geochemical exploration methods in the Xiaoxigong gold deposit and its periphery as well as in the areas whose arid desert gobi relict mountain landscape is similar to that of the Xiaoxigong gold deposit. -
