Comments on the geologic information

  • Geologic Description = This geothermal area is described by Randolph and Ellis (1989) as being similar to ARDF number UK011 - Steeple Point. 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 x 4000 foot color anomaly. It consists of acid-leached rocks and localized silica stockworks. Some of the fumarolic centers also display strong silicification and pyritization. Hot-spring centers exhibit silicification and calcedonic breccias. Combined metal values from 55 samples obtained here and at Steeple Point (ARDF number UK011) are up to >2000 ppm arsenic, 115 ppb gold, >5 ppm mercury, 11 ppm molybdenum, and 4.4 ppm silver.
  • Age = Quaternary.
