Peculiarities of the present structure of the Bug granulite complex developed within the Middle Bug area and its partitioning into series and suits

open access: yesГеофизический журнал, 2022
The Gaivoron-Zavalie site and the Golovanevsk suture zone (GSZ) of the Bug mining region (BMR) in the Middle Bug region have been a «testing ground» for studying the structure and stratigraphy of the Early Precambrian complexes of the USh for many years.

About the so-called «Bug series» of the Middle Bug region (Ukrainian shield). Article 1. The evolution of views and the composition of the «Bug series»

open access: yesГеофизический журнал, 2022
The name «Bug Series» was introduced into the Precambrian stratigraphic scheme of the Ukrainian Shield more than half a century ago. During this period, ideas about the composition and age of the series changed several times but, until recently, the ...

What happened to the Early Precambrian granulite complexes of the Bug region (Ukrainian shield) and the Limpopo belt (South Africa) and how to stratify them? A tectonist’s view

open access: yesГеофизический журнал, 2022
The author reviews two alternative approaches (stratigenic-metamorphogenic and deformation-metamorphogenic) to the geology and mapping of the Earth’s oldest crust rocks that were metamorphized in РТ-conditions of the granulite facies, on the examples of

On some aspects of the study of age ratios of rock complexes of the Ukrainian Shield

open access: yesГеофизический журнал, 2020
The article discusses the applicability of stratigraphic dismemberment in the study of high-temperature metamorphic complexes of the Ukrainian Shield. The effectiveness of the stratigraphic method with respect to these complexes was called into question

Rapid oxygen diffusion during high temperature alteration of zircon [PDF]

open access: yes, 2018
The mineral zircon through its isotopic and elemental signatures comprises the greatest archive recording the evolution of Earth’s continental crust. Recognising primary from secondary zircon compositional signatures is thus important for the accurate ...

Stages in evolution of Earth's crust recorded by the Huliaipole block of the West Azov area (4.0-2.0 Ga) [PDF]

open access: yes, 2020
The U-Pb age of zircon populations from metadacite of the Huliaipole Suite was determined using the LA-ICP-MS method as 3085-2850 and 3700-3360 Ma. In addition, two crystals of zircon were discovered with an age of more than 3800 Ma.
