Gold and Other Minor Elements Associated with the Hot Springs and Geysers of Yellowstone National Park, Wyoming, Supplemented with Data from Steamboat Springs, Nevada by Donald Edward White,Chris Heropoulos,Robert Orville Fournier,R. O. Fournier Pdf

A commonly held theory of the origin of epithermal ore deposits relates Au, Ag, Hg, As, Sb, Tl, and other "volatile" elements to "fossil" hot-spring systems that transported and deposited these metallic elements close to the ground surface existing at the time. In the early 1970's, an emission-spectrographic method using short-wavelength radiation (SWR) was developed for use in the analysis of these "volatile" elements. This method was applied to 125 samples of rock and hot-spring chemical precipitates from Yellowstone National Park and 43 samples from Steamboat Springs, Nev. The results of those analyses are presented here. Recently, other, more sensitive methods for the analyses of gold and volatile elements have been developed and (or) become less expensive, but these methods generally have not yet been applied to Yellowstone samples. -- First paragraph.

The Geysers of Yellowstone, Fifth Edition by T. Scott Bryan Pdf

This new edition of The Geysers of Yellowstone is the most up-to-date and comprehensive reference to the geysers of Yellowstone National Park, describing in detail each of the more than five hundred geysers in the park. The entire text has been revised and geyser descriptions have been updated based on activity observed through early 2018. Information about a number of significant new geyser developments has been added, as well as recent knowledge about some of the world’s geyser fields outside Yellowstone. Both a reference work and a fine introduction to the nature of geyser activity, this popular field guide includes a glossary of key terms, a comprehensive appendix that discusses other geyser areas of the world, detailed maps of each geyser basin, and tables for easy reference. The Geysers of Yellowstone will continue to serve geyser gazers as well as newcomers to geothermal phenomena for years to come.
