Maryborough (goldfield)

Central Victoria, Bendigo Zone (Western Lachlan Orogen), Australia

Orogenic goldAu

Type: Orogenic gold in quartz veins in Ordovician turbidites

Deposit of the Paleozoic Victorian goldfields, chevron-folded and cut by reverse faults; gold mostly deposited before the Devonian granites. Coordinates not published (map only).

ε107Ag in ε units (parts per 10,000) Values of the same system

Standard : NIST SRM 978a

Value	Range	n	Mineral or matrix	Source
1.6 ± 4.1 ε	−1.3 / 4.5 ε	2	silver-bearing native gold Mean and standard deviation recalculated from 2 analyses, -1.30 to +4.50 (M42560 +4.50; M18738 -1.30). Detail: M42560 (Maryborough, Au 99.14 %, Ag 0.82 %, Cu 400 ppm, ± 0.05); M18738 (Maryborough, Au 95.45 %, Ag 4.54 %, Cu 82 ppm, ± 0.02). ε107Ag = deviation of 107Ag/109Ag from SRM 978a in parts per ten thousand, opposite in sign to ε109Ag.
