Application of factor analysis in delineating geochemical element combination anomalies in the Haositai copper silver polymetallic deposit
This article uses factor analysis to delineate the geochemical element combinations of the Haositai copper silver polymetallic deposit,and compares them with the traditional single element anomaly superposition method.In traditional methods,neglecting the correlation between elements often leads to a large range of combined anomalies,scattered distribution of outliers,and poor correlation.Factor analysis can more scientifically and reasonably reflect the symbiotic relationship between elements,thereby narrowing the scope of mineral exploration and improving exploration efficiency.This article conducts R-type factor analysis on 12 geochemical elements,combined with KMO and Bartlett sphericity test to determine the suitability of the data for factor analysis,and divides the data into four main element combination factors.A combination anomaly map was drawn based on factor scores,and the lower limit of anomalies was calculated through box plots.Taking F1 factor as an example,the effectiveness of factor analysis in combination anomaly delineation was demonstrated.
