Gamma radiation was applied to natural and synthetic quartz. The different geological occurrences were clearly detectable by the wide range of smokiness. When irradiated by gamma rays, the smokiness grade was the highest in volcanic quartz, intermediate in granite, and the lowest either in schist quartz or in low temperature quartz of hydrothermal origin. After a heating test at about 1000 deg C for 30 minutes, a marked increase in the smokiness grade was seen. Thus smokiness grade seems to indicate the crystallization temperature of that quartz. The significance of this relation between smokiness and crystallization temperature appears to have escaped the considerations of geologists and mineralogists. The gamma irradiation method should be applied to the study of granite petrogenesis and ore deposits. (auth)
