A PETROLOGICAL MODEL FOR THE GENESIS OF THE MURUNTAU GOLD DEPOSIT

Abstract
Muruntau in Uzbekistan may be the largest hydrothermal gold deposit in the world. The three papers presented here, from three different organizations, suggest that consensus as to its genesis is a long way from being reached. In the first paper, Marakushev and Khokhlov summarize the geologic setting and offer a hypothesis of “fluid-magmatic replacement” of initially gold-rich carbonaceous shales by infiltration of a lamprophyric magma, a process the details of which unfortunately are left rather vague.
