Study of influence reef-building Bryozoa and algae of artinskian stage of the Permian System on regularities of lateral changing for thickness of stratas was used as a model for the development of creative paleotectonic analysis of stratas with reefs at the PreUrals. Essence of method: 1) map-development of series of paleostructures maps (or maps for thickness of stratas) for one territory, but for several adjacent stratigraphic subdivisions first on stratigraphic refeathers all without excluding the bore holes; 2) map development of paleostructures maps for same territory and for same stratas, but without bore holes with reefs; 3) investigate for reef facies; 4) full paleotectonic analysis for all stratigraphic intervals of investigations.
This strategy allows reveal "reefs" on anomalies of thickness some stratas, even though it was not recognized on the traditional maps of stratas thickness, in that events particularly, when "reefs" was not recognized or is not identify on core-samples from bore-holes bore holes. Elaborate regional tectonic and paleotectonic maps of the territory. This method can recognizes single-line structures, which are the most perspective for the searching for local oil and gas traps in reef-rocks of Devonian and Carboniferous stratas.
These creative exercises are updated by part of the classical course analysis for students, possibility, which greatly increase with using the computer technologies. These methods are use on the geological production.
