Gold Abundance in Igneous Rocks; bearing on Gold Mineralization
Economic Geology and the Bulletin of the Society of Economic Geologists (April 1973), 68(2):168-186
Abstract:
Review of quantitative data, restricted range in gold content (rarely more than 10 ppb, generally below 5 ppb), mafic rocks have more, so do early crystallizing minerals, no use in exploration, factors other than concentration determine mineralization; examples
