In the Kuznetsk basin, south-central Siberia, regression of marine conditions promoted simultaneous existence of many environments during Carboniferous and Permian times. Different sequences of fades in different areas complicate correlation. Floral, faunal and lithologic data have been mapped to determine succession of biologic complexes for four intervals of late Paleozoic time: 1) middle Ostrog suite (maximum marine transgression); 2) middle Alykayeva subsuite of the lower Balakhonikha suite (maximum Balakhonikha coal formation); 3) upper Kuznetsk and lower Il'ya suites (beginning of second stage of coal formation); 4) middle Uskat subsuite of Il'ya suite. These intervals were selected because they correspond to the peak development of conditions typical of their stratigraphic subdivisions, they are most easily correlated, and contain the most information. — Nicholas Hotton, III. |
