Geochemical studies of the epithermal deposits at Goldfield, Nevada
Creators
Abstract
Approximately fifty samples of vein material and wallrock from the ore deposits of Goldfield, Nevada, were quantitatively analyzed by means of the spectrograph to determine whether the quantitative distribution of certain elements would give some clue to the loci of mineralization. It has been established that three elements, bismuth, silver and tin, are genetically associated with gold values in the deeper veins. These elements are determinable even in very low grade vein material.The quantitative variation of some elements in the wallrock gives hope of determining the distance of a given wallrock sample from a vein.Vertical zoning at Goldfield is evident with respect to tin, less definite for bismuth and probably present among several of the accompanying elements.
