Ore-Forming Fluids of the Gold-Bearing Interval of the Kola Superdeep Borehole

Abstract

This paper reports on the physical–chemical parameters and vertical distribution of different types of fluid inclusions in quartz from the Au-bearing interval of the Kola Superdeep Borehole. We assume that gold ore mineralization was formed when a deep flux of CO₂ interacted with brines at depths of 10 205–9269 m due to tectonic factors. In this paper, we discussed the role of these processes in the formation of the orogenic gold deposits including the gold mineralization of the Southern Pechenga structural zone.
