Kravchenko O. Structural-lithological geological-genetic model of Krasnokutsk titanium-zirconium deposit

The geological structural and material composition of Miocene sediments within Krasnokutsk titanium-zirconium deposit have been investigated. The Novopetrivtsi suite lithofaces composition has been under consideration. A scheme lithostratigraphic subdivision for Novopetrivtsi suite of Krasnokutsk deposit area was developed; three subsuite were singled out: Lower Novopetrivtsi, Middle Novopetrivtsi (placer bearing) and Uper Novopetrivtsi. The detailed lithological (and metallogenic) characteristics of subsuite is presented. Digital structural-lithological model of Krasnokutsk deposits has been developed. The model reflects its characteristics: structural (the relief of Middle Novopetrivtsi subsuite top and floor, it's thickness and ore horizon thickness; matter characteristics including spatial distribution of ore material (in mineral forms - ilmenite, rutile, zircon, and their sum - bulk concentrate). Two forms of the model visualization - a profile (profile of contents diatribution) and area (maps of average concentrations spread specific resources spread, map of certain industrial and indicative parameters repartition etc.). Paleogeographic reconstruction of local and zonal level scale is carried out. Paleofacial scheme of Krasnokutsk deposit area (Middle Novopetrivtsi time) has been developed; the following facies have been singled out it: sea coastal (essentially ore-bearing), sea shelf (with scattered ore mineralization) and delta (ore-free). The general mechanism of placers forming has been proposed a set of search criteria for potential sites within Kharkiv and Sumy placer district was developed.
