Yevtyekhov Y. The comparison of bended iron and enclose formations of East-Annovka belt and Saxagan region, Krivoy Rog basin

Thesis for candidate's degree of geological sciences on a speciality 04.00.11 - geology of metal and non-metal raw materials. National mining academy of Ukraine, Dnepropetrovsk, 2001. The correlation of Annovskoe and V.I.Lenin mine deposits ferruginous sections is considered for clarification the age and stratigrafic relations of Saksagan and Northern regions of Krivoy Rog basin metavolcanic-sedimentary stratas. The attempt to creation a complex estimation of Krivoy Rog fer-ruginous deposits uniform model have been made. The beloning of Annovskoe deposit to upper Ar-chean ferruginous metaultrabasic-basic formation, and of V.I.Lenin mine deposit - to early Proterozoic ferruginous shist formation is substantiate. It is determined, that V.I.Lenin mine and Annovskoe deposits sections were formed asynchronously in different structural-facies zones. The geological development features of investigated objects had not rendered essential influence on their complex mineral base, because the majority of raw mater ials are connected with later metamorphic and hydrothermal-methasomatic processes.
