Comments on the geologic information

  • Geologic Description = This geothermal site is described by Randolph and Ellis (1989) as being similar to ARDF number UK005. The rocks consist of waterlain tuffs and lahars of Quaternary age. The site contains numerous fumaroles and hot-springs and is marked by a 7,000 by 4,000 foot color anomaly. It consists of acid-leached rocks and localized silica stockworks. Some of the fumarolic centers display strong silicification and pyritization. Hot-spring centers also exhibit silicification and calcedonic breccias. Combined metal values from 55 rock samples obtained here and at ARDF number UK005 are up to >2000 ppm arsenic, 115 ppb gold, >5 ppp mercury, 11 ppm molybdenum, and 4.4 ppm silver (Randolph and Ellis, 1989).
  • Age = Quaternary.
