近三年来,作者参与了化探找金的方法试验工作,本着“总结、提高”的精神,写成此文,以供同志们参考。 文中介绍了四川四种类型金矿的特征元素组合和它们的分散流异常特征;化探找金方法试验结果;进而对化探找金的工作方法提出了一些粗浅看法。 所采样品用发射光谱半定量分析方法测定Cu、Ag、Pb、Zn、Ni、Cr、Co、V、Ti、Mn、Mo、B、Ba、Bi、Sn,用化学光谱法测定Au,结晶紫比色法测定Sb,斑点
In the past three years, the author has participated in the experiment of the method of searching for gold by geophysical prospecting. Based on the spirit of “summarizing and improving”, this article is written for reference by comrades. In this paper, the characteristic elements combinations of four types of gold deposits in Sichuan and their anomalous characteristics of dispersive flow are introduced. The results of the geochemical exploration method for gold are also presented. Then, some superficial views are put forward. The samples were measured by semi-quantitative method of emission spectroscopy for the determination of Cu, Ag, Pb, Zn, Ni, Cr, Co, V, Ti, Mn, Mo, B, Ba, Bi and Sn by chemical means of spectrometry Colorimetric determination of Sb, spots
