Greenstone Structures of the Orikhovo-Pavlograd Zone: First Experience of the Geological Description. Article 1. Novohorivka Structure

Language: Ukrainian

Mineralogical journal 2015, 37 (4): 68-77

Abstract: The article gives a historical analysis of the identification and description of greenstone structures within the Orikhovo-Pavlograd deep fault zones. The structural and tectonic position, ordering of the internal structure and composition of the rocks of the Novohorivka structure, discovered among the real and genetically different types of rock associations — the basement of greenstone formations has been described for the first time. The article assesses the radiological age of the rocks, involved in its structure. Based on the characteristics of mineral composition of the rocks and their position, three distinct parts (KT-1, KT-2 and KT-3) of the metakomatiite-tholeiitic formation and their stratigraphic analogues (Sura, Olginske suites and Kosyvtseve stratum) were described.

Keywords: greenstone structure, Orikhovo-Pavlograd deep fault zone, metakomatiite-tholeiitic formation, Sura suite, crosssection correlation.
