Stable isotope data for sulfur, oxygen, and hydrogen in minerals and gases and electron microprobe data for minerals from Sulphur Bank mercury mine, Lake County, California

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-02-21T00:00:00Z
Stable isotope compositions (the ratios deuterium/hydrogen, oxygen-18/oxygen-16, and sulfur-34/sulfur-32) are reported for alunite, jarosite, kaolinite, silica, cinnabar, marcasite, and native sulfur from outcrops in and around the workings of the Sulphur Bank mercury mine, Lake County, California, and chemical compositions are reported, from electron microprobe analyses, for alunite and buddingtonite. Isotope analyses are given also for hydrogen sulfide gas from active fumaroles and for soluble sulfate in samples of mine waste. The waste results reflect fine grained material (particles less than 0.063 millimeter in diameter) that were taken from composites, each composite representing a particular waste pile that was active during a particular period of mining.
