| Abstract: | Electron microprobe analysis of pyrites from a mlcro-disseminated gold deposit in Guizhou has revealed four micro-grains of gold. This paper describes the theoretical grounds for electron microprobe research on micro-grained gold and the technological problems concerning the application of this approach, and also introduces the method of calculating the detect limits and measuring techniques. In addition the content of trace gold has been determined in pyrites, and the existing forms of micro gold are also presented. |
