The Correlation of Indicator Elements in Structural Superimposed Halos for Concealed Gold Prospecting and Its Significance
摘要
Abstract
The study and correct understanding of the correlation between gold indicator elements are of significant theoretical importance and practical value for the prediction of concealed gold deposits using structural superimposed halos.Some scholars believe that the indicator elements for predicting blind gold deposits should be positively correlated with gold,with higher correlation coefficients being preferable.However,this is not entirely the case in practice.In hydrothermal gold deposits,ore-forming and associated elements were precipitated from mineralization fluids to form ore bodies and halos.Theoretically and macroscopically,these associated elements were closely related to gold,with halos being more extensive than ore bodies and thus easier to detect.As a result,associated elements serve as excellent direct indicators for gold prospecting.Gold ore bodies and their halos exhibit distinct axial zoning,with each ore body possessing its own frontal halo,near-ore halo,and rear halo.Theoretically,gold is only positively correlated with near-ore halo elements and shows no correlation with frontal or rear halo elements.However,in practice,the calculation of the correlation coefficient matrix for the orebody-halo indicator elements often results in complex and seemingly chaotic relationships.For example,gold may appear correlated with frontal halo elements(e.g.,Hg)or rear halo elements(e.g.,V,Ti),which reflects the complexity of gold-associated element relationships resulting from multi-stage mineralization and superposition.Further research indicates that this complexity largely reflects the intensity of hydrothermal activity.Combined with the anomaly strength of indicator elements,it serves as a favorable indicator for determining the presence of concealed deposits at depth.关键词
