Geological journal| Резюме: | In the history of Ukrainian Paleozoic foraminifera research three periods can be clearly defined. First one – the 30’s till the end of the 40’s – beginning of the 50’s of the last century. At this time the research of Late Paleozoic foraminifera of Ukraine and their usage for the purposes of stratigraphy started.The second period is directly associated with the fast growth of drilling activity caused by fossil fuels exploration in the Devonian and Carboniferous deposits. It lasted almost till the end of 90’s of the last century. This period was the most productive for foraminifera and stratigraphic research. It is characterized by construction and ratification of the detailed stratigraphical schemes of the Upper Paleozoic and especially Carboniferous deposits of Donbas, Dnipro-Donetsk, Lviv and Dobrudja Foredeep. In the biostratigraphic part of these schemes foraminifera played the leading role. Significant number of major joint works with description of foraminifera is characteristic of this period.The third period is connected with the substantial diminish of exploration of Upper Paleozoic deposits of Ukraine. This led to the decreasing of research activities on stratigraphy and foraminifera of these rocks. Thus, while at the beginning the number of experts in Paleozoic foraminifera didn’t exceed 7-8 and then grew up to almost 30, at the present time there are no more that 3-4 of them. Biostratigraphic research nowadays is mostly focused on the modernization of existing stratigraphical schemes. |
