One of main issues in geochemical exploration is that primary haloes of some deeply buried mineral deposits cannot be investigated, or that anomalies of these haloes are too weak to be analyzed. The superposition characteristics of the primary haloes can help us to identify the axial variation of the indicator elements in ore bodies more easily, and then provide a strong indication of the presence of buried ore bodies. This study uses multi-element lithogeochemical data (n = 924) to study the primary haloes of the Daping gold mineralization and the elements associated with the mineralization. First, correlation coefficient matrix was used to study the correlation among the elements in the samples with an Au grade greater than 1 ppm, and the results were used to study the element combination of the deposit. Secondly, Gregorian's method was used to calculate the axial zonality series of the indicator elements. Then, based on the content of 18 elements in 11 existing middle mining sections, the axial variation of the indicator elements was studied. Finally, based on the concentration zonality of the elements and the axial variation of the indicator elements, four deep targets of No.V1-2-3 gold-bearing quartz vein were proposed. Buried ore bodies were found by two boreholes in the No. II predicted target area, which demonstrated usefulness of the methods in this study. The results of this paper provide an example for the application of the superposition characteristics of primary haloes in deep mineral exploration for similar types of gold mineralization in other areas.

地球化学勘探的主要问题之一是无法研究某些深埋矿物矿床的原始晕圈，或者这些晕圈的异常程度太弱而无法分析。原始晕圈的叠加特征可以帮助我们更容易地识别矿体中指示元素的轴向变化，然后为埋藏矿体的存在提供有力的指示。本研究使用多元素岩石地球化学数据（n = 924）研究大坪金矿化的主要晕圈以及与该矿化有关的元素。首先，使用相关系数矩阵来研究金级大于1 ppm的样品中元素之间的相关性，并使用结果来研究沉积物的元素组合。其次，采用格里高利法（Gregorian's method）计算指​​示单元的轴向纬度序列。然后，根据11个现存中部采区中18种元素的含量，研究了指示剂元素的轴向变化。最后，根据元素的浓度分区和指示元素的轴向变化，提出了V1-2-3号含金石英脉的四个深部目标。在II号预测目标区域的两个钻孔中发现了埋藏的矿体，证明了该方法在本研究中的有用性。本文的结果为其他地区相似类型金矿的深层矿物勘探中原始光环的叠加特征应用提供了实例。
