Trace elements in coloured opals using neutron activation analysis

  • G. D. McOrist
  • A. Smallwood


Neutron activation analysis was used to determine the concentration of trace elements in 50 samples of orange, yellow, honey, green, blue and pink opals as well as 18 samples of colourless opals taken from a number of recognised fields in Australia, Peru, Mexico and USA. The results were evaluated to determine the relationship between trace element content and opal colour.
