近、现代的科学研究对金的地球化学特征有了比较清楚的认识，众多学者也给出了它在地壳中的丰度（克拉克值，多在３．５×１０－９～５×１０－９间），并统计研究了金在不同大地构造单元、不同岩性、甚至地球上不同介质中的丰度。随着“区域化探”的提出和实施，甘肃的金矿地球化学勘查与全国同步，并取得了骄人的成绩。用勘查地球化学方法找到了本省的第一个规模达中型以上的独立岩金矿床，发现并探明了大型矿床规模的大水金矿、李坝金矿。证明了区域化探异常查证是普查找金的主要手段。区域化探扫面的实施使勘查地球化学提高到一个崭新的水平。
Near and modern scientific research has a relatively clear understanding of the geochemical characteristics of gold, and many scholars have also given its abundance in the crust (Clarke value, more in the 3.5 × 10-9 ~ 5 × 10- 9), and statistically studied gold in different tectonic units, different lithology, and even the abundance of different media on Earth. With the introduction and implementation of “regional geochemical exploration”, the geochemical exploration of gold deposits in Gansu has been synchronized with that of the whole country and remarkable achievements have been made. Using exploration geochemical method to find the province’s first large-scale independent rock gold deposits, found and proved the large-scale mineral deposits Dashui gold, Li Ba gold. It is proved that abnormal geochemical exploration in the area is the main means of finding gold by census. The implementation of regional geochemical scanning planes has elevated exploration geochemistry to a whole new level.
