Reply to "Comments on the use of gamma-ray spectrometry for tin and tungsten prospecting"

Abstract

In previous studies comparing the radiometric signatures of exposed "barren" and Sn/W (as wolframite) mineralized granitoids in southeast Australia (Collins et al1981; Yeates 1982; Yeates et al1982) it was demonstrated that the uranium value of a granitoid is significant in terms of its suitability as a source of, or host to, associated mineralization. Prospective granitoids have more than 4 or 5 p.p.m. U (in various areas) and the abundance of U can be measured simply in the field with a portable four-channel gamma-ray spectrometer housing a sufficiently-sized NaI crystal detector (Collins et al1981, pp. 3?4).
