Vishnevskaya E. Petrology of the dyke rocks from Bobrynets Belt (Ingul megablock of the Ukranian Shield).

Object of study dykes rocks from Bobrynets Belt Ingul megablock of the Ukrainian Shield. The main purpose of the thesis clarification petro-genetic conditions formation dyke rocks from Bobrynets Belt, formational determine their accessory and metallogenic specialization and the development of mineralogical and petrographic and geochemical criteria correlation and dismemberment dyke formations Ingul megablock Ukrainian shield. The results of the research allowed the author to divide Bobrynets dike belt into two petrographic associations - dolerite-diabase and ultramarfite-lamprophyre. It is assumed that the origin of the associations was due to two separate phases of magmatism that were not related through a common process of magmatism evolution.
