Abstract

Barth's concept about sodium ingress into metamorphic rocks directly from the buried seawater sediments is considered in the paper. This concept solves the problem of sodium balance according to the Vernadskiy studies of geochemical cycles. Basing on this concept, sodium geochemistry in auriferous terrigenous complexes in different regions of Russia and other CIS countries is analyzed. It has been demonstrated that the sodium enrichment in terrigenous rocks occurs not only during the metamorphism process but also in formation of sedimentary rocks under the conditions of avalanche sedimentation and fast sediments immersion in the zone of catagenesis. The sodium is fixed in albite under thermodynamic conditions of catagenesis. Chloride is not finding its own mineral phase and transports gold from the mineral phase to the exfiltration silicate waters, because it has the high activity with respect to gold. Metallogenic result of this process is the formation of auriferous quartz veins and stringer zones in drain sandstone beds. Metallogenic specialization of normal potassic terrigenous sequences is determined by different factors displayed during the processes of sediment genesis and diagenesis or the future processes of metamorphism and (or) intrusive magmatism.
