OREAS 20a
OREAS 20a has been prepared from barren I-Type hornblende-bearing
granodiorite sourced from the Upper Devonian Lysterfield granodiorite complex
located in south-eastern Melbourne, Australia. It is characterised
for multiple analytical methodologies for full ICP-OES and ICP-MS
elemental suites and contains very low background gold of less than 3 parts
per billion.
