Main results of geological and geophysical research on the Zelenogayska structure of the Ingulsky megablock of Ukrainian shield

Abstract

The analysis of the main results of the complex of geological and geophysical research carried out over many years in the Zelenogayska structure of the Ingulsky megablock UkrSh is presented in the article. Conclusions about explosive endogenous genesis of the Zelenogayska structure are substantiated. This structure according to the complex of geological and geophysical data is two weakly eroded volcanic craters of the explosive maar type. A number of specific features of this structure are determined in this article. These features have many common with the Argyle pipe, the Helendale-4 of the Halls Creek and King Leopold areas in Northwest Australia. The degree of manifestation of these features in geophysical fields is established in the paper. The general conclusions, recommendations and other results of the performed works, at the same time, are the details, the justification for future research in this direction. The practical significance of the study is to increase the effectiveness of forecasts by expanding the range of deep factors used and the criteria for the formation of diamondiferous structures on the Ukrainian Shield, as well as geophysical and petrological-geochemical indicators of their localization. This makes it possible to improve the efficiency of geological prospecting.
