- Abstract
The paper presents results of experiments aimed at diamond synthesis in the Fe-C-S system at 5.3-5.5 GPa and temperatures of 1300-1370°C and detailed data on the microtextures of the experimental samples and the composition of the accompanying phases (FeC and FeC carbides, graphite, and FeS). It is demonstrated that diamond can be synthesized after temperatures at which carbides are formed are overcome and can crystallize within the temperature range of 1300°C (temperature of the peritectic reaction melt + diamond = FeC) to 1370°C (of thermodynamically stable graphite) under the appearance experimental pressure. The possible involvement of natural metal- and sulfur-bearing compounds in the origin of natural diamond is discussed.
