Kostenko N. The regional peculiarities of trace element composition of granitoids of Precambrian tectonic-magmatic activization (by the example of Ukrainian Shield)

Work is devoted to studying of the stages sequence of for-mation of granitoids of Precambrian tectonic-magmatic activi-zation of the Ukrainian Shield and their specializations on the basis of the analysis of their trace element composition. Proc-esses of activization in region for the first time are investi-gated at a quantitative level. As a result of the carried out re-searches it is determined 4 stages of processes of activization of granitoid type on Ukrainian Shield. It is proved 2 stages displays of these processes in each of the allocated stages. There was allocated 2 groups of the granitoid rocks with dif-ferent degree of activization. It is carried out petrogeochemical analysis of granites of different stages of activization in region. Are determined characteristic features of granitoids of differ-ent stages of activization on the Ukrainian Shield. Geological objects with different types of geochemical (metalogenical) specialization of granitoids of epoch of tectonic-magmatic ac-tivization onUkrainian Shield were determined.
