Abstract

This article presents the characteristics of the resource base of building sands within the three Podillya regions, the patterns of sands distribution, and proposals for increasing the extraction of raw materials . The construction sands of Podillya are confined to the Upper Cretaceous, Neogene and Anthropogenicdeposits. The decrease of the thickness of the sandy strata of the Opilsk Neogene suite in the eastern direction was observed with the simultaneous increase in the thickness of the overlapping strata of the rocks. There is no apparent correlation between the thickness of sandy interlayers and the quality of sands. The interdependence of the chemical composition of Neogene sands and the sand size module is established.The genetic predisposition for the distribution of building sands in different parts of the Podillya territory has been established. Four groups of sand deposits of different age have been identified within the Podillya regions, which contrast sharply with single deposits in the neighbouring territories.There is a very uneven distribution of explored reserves of sandy raw materials across the region and accordingly in the provision of construction sands in the different oblasts /regions of Podillya. The areas best provided with sandy raw materials are the central districts of Ternopil region and Slavutsky district of Khmelnytsky region . Sands of the Baltic stage distributed in Vinnytsia region are mostly poor in quality, clogged with clay material and require enrichment. The further development of the mineral raw material base and the prospects for increasing the production of construction sand in the Podillya regions is associated with the increase in production at the prepared deposits, the commissioning of reserve deposits, the conducting of prospecting and exploration work in the proposed potentially exploitable areas and additional exploration of individual deposits that are exploited. The research allows us to evaluate objectively the existing base of sand raw materials for various purposes in the Podillya region and to develop on this basis measures to increase it. The importance of the study is determined by the acute shortage of the raw material in most administrative districts of Khmelnytsky and Vinnytsia regions, by the growth in the volume of construction work (and accordingly the requirements for sandy raw materials) both in Podillya and in the country.

Highlights

The Podillya region (Ternopil, Khmelnytsky and Vinnytsia regions) is relatively poor in explored reserves of construction sands (5.9% of the explored reserves in Ukraine)
We consider that conducting research aimed at generalizing the available information on the present state of the raw material base of construction sand for various purposes in the regionisof current and urgent interest
The tasks performed by the conducted research were as follows: a) to establish thepatterns ofdistribution of sandy deposits of different ages, their functions and genesis on the territory of Podillya regions; b) toanalyze the degree of exploration of Podillyasandy deposits; c) to establish the provision ofbuildingsandfor different purposes to administrative units of the region; d) to propose some possible ways to increase the raw material base and to increase the production of building sands in the region

Summary

Introduction

The Podillya region (Ternopil, Khmelnytsky and Vinnytsia regions) is relatively poor in explored reserves of construction sands (5.9% of the explored reserves in Ukraine). The sands of the Badenian stage of the Neogene series are distributed in the southwestern, western and central parts of Ternopil region and are represented by deposits of two formations: Opillia and Kosiv, according to the nomenclature adopted by geologists-industrialists. The sands of Opillia formation are quartz, fine-grained and very fine-grained, argillaceous,some sections are ferruginized, light grey, yellowish-brown and dark grey Their thickness varies widely - from 22.5 to 12-18 meters. There is a clear interdependence between the content of different size particles and the chemical composition of sands: with an increase in the content of particles smaller than 0.16 mm, the content of silica is drastically reduced and the content of alumina is increased This revealed feature can be used to predict the qualitative characteristics of sands in the new and less explored areas. Several deposits are found in Husiatyn, Pidvolochysk and Kremenets districts of the region, and they are referred to Kosiv formation of the Middle Miocene (Yablunivske, Maloberezhtsivske)
