At the Red Dome and Mungana deposits in north Queensland, Australia, it is proposed that mineralisation and alteration
developed as a "telescoped" overprinting continuum, ranging in style from hypothermal to epithermal, reflecting the
major changes that developed in the regional setting over the period circa 325 - 290Ma. Regional assessment suggests
that this also applies to many other precious and base metal deposits within a 401an length of the host Siluro-Devonian
Chillagoe Formation. A ten stage paragenetic sequence of structural preparation, multi phase intrusion and associated mineralisation,
alteration and brecciation is postulated for the Chillagoe district.
