Origin of the conditions favorable for the formation of the placer platinum presence in the re- gion is governed by the plume ore-generating magmatism of several generations ( in Proterozoie and Phanerozo- ic). Ultramafite-mafite magmatism was responsible for the origin of the stratified zonal massifs subjected in the Late Paleozoic and Mesozoic to the action of granitogene derivations of the NAS. The latter provided the devel- opment of the ore-forming magmagene-fluid-metasomatic processes and favorable conditions for the platinum group elements concentration.展开更多

The purpose of the research was to introduce the method of students' presentations in foreign language teaching, as well as the topics related to the culture and civilization of the English-speaking countries. After the introductory lectures on how the presentation on the given topic in the English language should be prepared, and after the presentations were delivered by the students during one semester, the results of the questionnaires which the students had to solve at the beginning and the end of the semester, were compared. The goal of the research was to examine the extent in which the students acquired the contents presented to them in such a way. The obtained results are satisfactory, although they have not fully met the expectations. However, if the problems and flaws are identified and addressed, the method can be further improved and better results achieved, both regarding the foreign language competencies, as well as multicultural awareness of young people.展开更多
