ACADEMICIAN YEVHEN LAZARENKO MINERALOGICAL SCHOOL AND ITS CONTRIBUTION TO THE DEVELOPMENT OF MODERN MINERALOGY

Abstract

Academician Yevhen Lazarenko mineralogical school, approved by the Ministry of education and science of Ukraine, occupies a special place among the world famous sci-entific schools, which originated and developed at the geological faculty of Ivan Franko National University of Lviv. The school began to form in the second half of the twenti-eth century thanks to the active research activities of the Mineralogy department of Lviv University and Lviv geological society, which were headed almost a quarter of the cen-tury by Ye. Lazarenko. The development of the school was also closely connected with the Ukrainian mineralogical society (founded in 1970). Regional mineralogical re-searches conducted by Ye. Lazarenko, crystallochemical and petrographic – by V. So-bolev, crystallographic – by G. Piotrowski, thermobarogeochemical – by M. Yermakov, the works of students and followers of these scholars, as well as the activity of Lviv geological society (founded in 1945) played an important role in the origin and devel-opment of the school. The first mineralogical periodical in Ukraine – “Mineralogical Review” – began publishing in 1947. Later, new mineralogical magazines appeared – “Mineralogical Journal” (1979), “Notes of the Ukrainian mineralogical society” (2004), thematic col-lections “Mineralogy of Sedimentary Rocks” and “Regional and Genetic Mineralogy”. Yevhen Lazarenko mineralogical school develops the following scientific direc-tions: regional mineralogy, theoretical problems of mineralogy, mineralogical crystal-lography, cosmic mineralogy, genetic mineralogy, applied mineralogy, biomineralogy, history of science. In Ukraine, representatives of the school began structural mineralogy and crystallochemistry, mineralogical crystallography, cosmic mineralogy, the study of accessory minerals, the doctrine of typomorphism of minerals, the basics of regional mineralogical investigations methodology and mineralogical mapping, biomineralogical research. Representatives of the school are such well-known scientists and pedagogues as Z. Bartoszynski, S. Bekesha, U. Fenoshyna, V. Kvasnytsya, H. Kultchytska, O. Mat-kovskyi, Yu. Melnyk, V. Melnykov, V. Pavlyshyn, V. Semenenko, L. Skakun, M. Slyv-ko, Ye. Slyvko, B. Srebrodolskyi, P. Vovk, E. Yanchouk, A. Yasynska, F. Zuzuk et al. Mineralogists of Lazarenko's school first discovered some new mineral species – donbassite and tarasovite in Donetsk basin, carpathite in Transcarpathians, acetamide and paraalumohydrocalcite in anthropogenic products. Also some new mineral varieties were discovered: brunckite – cryptocrystalline sphalerite and Mn-ferrostilpnomelane – the variety of stilpnomelane. The first finds in Ukraine of very rare minerals also belong to school representatives: chlorophaeite in Western Volynian altered volcanic rocks, fer-ruginous saponite in the igneous rocks crusts of weathering in Western Volyn, chamber-site in potash salt ores of Precarpathians (the second finding in the world), dannemorite in Mn silicate-carbonate ores of Chyvchynski mountains (Carpathians), daphnite (fer-ruginous variety of chlorite) in chamber pegmatites of Volyn region, Ti-biotite 4M in camptonite dikes of Azov region, groutite in Mn-containing rocks of Zavalivske graph-ite deposit etc. Ukrainian mineralogists first discovered in the territory of the former USSR such minerals, as basoaluminite, millosevichite, pickeringite, and also the second finds in the world of lausenite and matteuccite belong to them. The activity of the Ukrainian mineralogical society, especially its Kyiv and Lviv branches, plays the decisive role in the development of Yevhen Lazarenko mineralogi-cal school. At the periodic congresses of the society, its members summarize the results of mineralogical studies for certain periods and discuss different actual problems of mineralogy. Periodic Yevhen Lazarenko scientific readings are conducted in Ukraine since 1997. The last, Tenth scientific readings were held in September 2016. Now representatives of the mineralogical school are working on the compilation of the Mineralogical encyclopaedia of Ukraine, embodying thereby the ideas of the aca-demician Lazarenko.
