Abstract
This paper presents carbon stable isotopic compositions of CO2 in fluid inclusions trapped in quartz, hosted by rocks of the Krivoy Rog banded iron formation (BIF). The fluid inclusion data are compared with published carbon isotopic compositions of carbon-bearing surrounding rocks. The study aims to provide the understanding of the processes that led to the formation of high-grade Fe ores. Fluid inclusions preserved in quartz from different stratigraphic units contain gas mixtures of CO2 +/- N-2 +/- CH4. The delta C-13 values of CO2, which is the dominant gas species in inclusions, range between -2.7 and -11.7 parts per thousand. Methane and nitrogen were detected in trace amounts. The results show that negative delta C-13 values of inclusion gases in quartz from ore and schist horizons may be correlated with magmatic or metamorphic carbon sources. The carbon isotopic compositions of gaseous fluid inclusions in quartz from the thrust zone area are more variable compared to those in quartz from areas which were not affected by thrusting.
