| Abstract | ||
| Gold mineralization of the target area is mainly confined to the Meta volcanic, Meta sedimentary rocks of green schist fanciesintruded by granitioid rocks. To reveal secondary dispersion haloes, unconsolidated soil samples were collected along profiles, across the suspected Au-bearing sector. Resultsobtainedfor Au and associated elements (Ag, Co, Pb and Zn), were subjected to statistical analysis to reveal parameters such as background value (Cb), coefficient of correlation, coefficient of variation, geochemical factors, productivities, and coefficient of dispersion. Statistical methods interpretation of the data proved to be effective and complement each other. Geochemical factors and ratios of contents of epithermal elements to hypothermal elements indicate deeper levels of mineralization and weathering, gold dispersion shows erratic behavior. The morphology of secondary dispersion haloes of one element reflects more or less the morphology of the hidden ore bodies. | ||
