| Summary |
"Definition Of The Study. The study consists of an investigation of the variation in the temperature of formation of sphalerite on the 500 and 1500 ft levels of the Balmat zinc deposit at Balmat, New York. A subsidiary investigation was performed on the use of x-ray fluorescence as a means of chemical quantitative analysis. Twelve samples of sphalerite from the 500 ft level and 13 samples from the 1500 ft level were analyzed for atomic percent iron content by measuring Zn/Fe x-ray fluorescent ratios. The x-ray fluorescent ratios were standardized by ''wet" quantitative analysis. The results of the analyses are applied to the FeS-ZnS phase diagram developed by Kullerud (1953). The locations of the samples from Balmat are recorded on maps of the two levels to enable a study of the horizontal and vertical variation of the temperature of formation"--Introduction, leaf 1. |
