Thermal and chemical conditions of formation of the Que River massive sulphides and precious metal zone. AMIRA Report (84/P210), April 1989 (CODES publication 20)

Abstract

INTRODUCTION The precious metal zone at Que River is an area in the northern parts of the eastern footwall containing anomalously high amounts of gold and silver relative to base metals when compared to the sulphide orebodies and the rest of the stringer system. The results of earlier work on the precious metal zone may be found in McGoldrick & Large (1987) and Jenkins (1988). In this report, the results of fluid inclusion thermometric measurements on the precious metal zone and parts of PQ lens are presented, and further conclusions are drawn regarding the origins of the precious metal zone.
