Geochemically anomalous rock samples, and their implication for the occurrence of a hot-spring type gold deposit, from Baker (Abraham) Hot Spring, Juab County, Utah

This report is preliminary and has not been reviewed -for con-formity with U.S. Geological Survey editorial standards and stratigraphic nomenclature.Any use o-f trade names is -for descriptive purposes only and does not imply endorsement by th< USGS.CONTENTS i i Summary Baker Hot Spring contains geochemically anomalous amounts o-f gold, arsenic, antimony, manganese, tungsten, and beryllium.The material containing the geochemical anomalies consists o-f manganiferous tufa deposited from an active hot spring system on the Sevier Desert a -Few hundred meters east of the edge of a basalt -flow associated with Fumarole Butte.The Baker Hot Spring area contains geologic and geochemical traits similar to better exposed hot spring mineral systems, such as at Golconda, Nevada, Sulphur, Nevada, and parts of Creede, Colorado, which have been mined for metals including gold, silver, sulfur, tungsten, and manganese, and may contain economic concentrations of these, or possibly other, metals in the subsurface.
