摘要
Based on a study of the regional geological settings and geological characteristics of the mining area, the gold anomaly halos in soil were analyzed mainly in Liujiapo region. The results show that the distribution of soil halos is consistent with the spreading direction of the structure, and the selectivity of halos to strata is not obvious. Through the analysis of Rcluster and correlation of eight elements (gold, silver, mercury, arsenic, antimony, lead, zinc, bismuth which were analyzed in geochemical exploration soil survey), it can be seen that Hg and Sb are the most relevant, Au and As are closely related, and they belong to the same indicators. It is also shown that Au, As, Hg, Sb have a certain degree of relativity, while Pb, Zn and other elements have almost no relevance but are independent.
