Outline of Final Research Achievements

This study established the lithostratigraphy of the Tsagaan Oloom, Bayan Gol, and Salaany Gol formations in Govi-Altai Province of western Mongolia, and analysed their sedimentary facies. The results indicate the location of the Ediacaran-Cambrian boundary (ECB), temporal changes in ichnofacies, and the first appearance horizons of small shelly fossils as well as of calcimicrobes and calcimicrobial reefs. The calcimicrobial reefs above the ECB are represented by thrombolites and stromatolites, and the calcimicrobes Renalcis and Epiphyton are common. Flat pebble conglomerates provided structurally stable substrates for the initial and stabilising stages of calcimicrobial reefs. Archaeocyath-calcimicrobial reefs of the Salaany Gol Formation are composed of archaeocyath frameworks with variable types of growth morphology, and inter- and intraframework bindings and infillings by calcimicrobes and carbonate cement. These geobiotas are markedly different from those of the Ediacaran Period.
