Mineral resources of Cherkasy region
Cherkasy region in Ukraine is rich in various mineral resources, which are divided into several categories:
1. Fuel minerals:- Brown coal
- Peat
- Ferrous metals
- Non-ferrous metals
- Precious metals
- Radioactive metals
- Raw materials for metallurgy (non-ore minerals)
- Fluxing and pelletizing materials for iron ore concentrates
- Mining raw materials
- Jewelry raw materials
- Raw materials for facing (decorative) materials
- Construction raw materials
Cherkasy region is located at the intersection of two subprovinces in Ukraine. Here, metallogenic regions are identified where many deposits of metallic minerals are located. This particularly concerns structural-metallogenic zones such as the Bila Tserkva, Holovanivsk, and Zvenyhorodka–Bratsk regions. The territory also contains important deposits of secondary kaolins, bentonite clays, and construction materials.
Brown coal
The industrial presence of brown coal deposits is associated with sediments formed by continental processes and is located within ancient paleovalleys on the crystalline basement rocks. Typically, the depth of occurrence of these coal seams averages from 30 to 60 meters.
Within Cherkasy region, two deposits have been identified. The Ryzhanivske deposit is located in the Ryzhaniv paleovalley and includes brown coal seams occurring among sediments of former lakes and swamps. The geological section consists of various deposits, including marine sediments of Paleogene and Neogene origin, as well as Quaternary deposits of different types. Currently, this deposit is not actively developed or exploited.
The Zelenkivske deposit is located near the village of Zelenkiv and belongs to the Zelenkiv paleovalley of Buchtach age. It consists of two parts. The western part contains four separate brown coal seams with thicknesses ranging from 0.5 to 5.1 meters and an average depth of about 42 meters. The eastern part contains brown coal with an average thickness of 2.6 meters and occurs at depths of up to 51.4 meters. The deposit is not currently being exploited.
Peat
Peat deposits are located along the Ros, Hnylyi Tikych, and Hirskyi Tikych rivers and their tributaries. Peat has a dark brown or dark brownish color and contains plant remains. The thickness of peat layers varies from 0.3 to 2 meters, with an average thickness of about 1.3–2 meters. There are 25 peat deposits within Cherkasy region, some of which are periodically exploited.
Iron
Within the Volodarsk ore field, iron ores of metamorphogenic origin have been identified. They are associated with ferruginous quartzites of the Volodarsk–Bila Tserkva sequence. This occurrence is located approximately 10 km north of the city of Bila Tserkva. Magnetic anomalies are caused by the presence of ferruginous quartzites among the surrounding rocks, forming an uplift with a complex faulted geological structure. The content of soluble iron in these ores ranges from 16.93% to 42.15%. However, this occurrence has no industrial significance.
Manganese
Occurrences of manganese in the Cherkasy region have been identified within the Holovanivsk metallogenic area, in the Northern Yatran ore field and at the Sverdlykivsk occurrence. The ore zones contain garnet–biotite graphite-bearing gneisses with manganese contents ranging from 6% to 14%. These occurrences require further investigation.
At the Sverdlykivsk occurrence, fragments of granites containing up to 18.39% manganese have been found. Pyrolusite–psilomelane ores with up to 60% manganese oxide have also been identified in the weathering crusts of rocks. However, these occurrences have no practical significance due to their small scale.
Aluminium
The Zvenyhorod occurrence is located near the village of Hudzivka and is associated with bauxite-like rocks formed through lateritic weathering processes. These rocks occur at depths of up to 93 m within sandy-kaolin deposits of the lower Cretaceous. The thickness of the deposit varies from 0.2 to 10.5 m. The bauxite-like rocks have a loose structure but a low alumina content (up to 17.1%), which makes this occurrence unsuitable for industrial exploitation.
Copper and nickel
The Pavlivsk occurrence is located about 2 km southeast of the village of Pavlivka and is associated with the western part of the Pavlivka gravity anomaly. The zones contain minerals such as pyrite, pyrrhotite, chalcopyrite, and occasionally arsenopyrite. The copper content in these zones ranges from 0.1% to 0.3%, nickel content from 0.11% to 0.13%, and graphite content may reach up to 20%. However, the occurrence is still insufficiently studied.
Titanium and titanium–zirconium
In the Cherkasy region, the Tarasivka–Tarashcha area is located, which includes the Tarasivske deposit and several occurrences of titanium–zirconium ores. The Tarasivske deposit extends for more than 20 km from southeast to northwest and contains sands enriched with titanium and zirconium minerals. There are also additional titanium–zirconium occurrences within the Tarashcha area that require further investigation.
Tantalum and niobium
The Murzynsk occurrence is located west of the village of Murzynci. In pegmatites that have undergone metasomatic alteration, low concentrations of tantalum (0.02%) and niobium (up to 0.03%) have been found. This occurrence is associated with tectonic faults of submeridional orientation that are part of the Pervomaisk fault system. These deposits require further study.
Gold
In Cherkasy region, gold concentrations have been identified in mineralization points and geochemical zones within the weathering crust of the crystalline basement. Within the Talnivka metallogenic zone (the Savyra ore field), the Maiske deposit is located. It is associated with a sequence of gneisses, migmatites, and amphibolites that have undergone intense hydrothermal–metasomatic alteration (silicification and biotitization). Gold mineralization, mainly represented by native gold, is associated with these altered rocks forming steeply dipping ore bodies. In the lower Cretaceous sand–gravel deposits, numerous gold aureoles have been identified, with the highest content (920 mg/m³) recorded at the Skrypchynecke occurrence. However, due to their great depth, small thickness, and limited area, these deposits have no independent industrial significance. Instead, they are used as indicators for prospecting primary gold sources.
Uranium
The Berestovets occurrence is located west of the village of Sushkivka and is associated with uranium ores in granitoids of the Uman complex, which contain pegmatitic granites. Uranium content in these ores ranges from 0.073% to 0.13%. Uranium occurs in minerals such as uraninite, autunite, as well as thorite and monazite. Uranium is also present in carbonaceous deposits of the Novopetrivska suite, though in different mineral forms.
Kaolin
Secondary kaolin deposits are located in paleovalleys within the crystalline basement and in sediments of the Smila strata of the Lower Cretaceous. Secondary kaolin is formed as a result of reworking and transport of weathering crust material. It is mainly used in ferrous metallurgy for the production of refractory materials. The presence and quality of kaolin depend on alumina content and sand contamination. Some deposits are actively developed (Murzynske, Novoselytske, Ryzhanivske), while others require further study (Zalizniachkivske, Ozirnianske, Zvenyhorodske).
Bentonite clay
In the Cherkasy region, bentonite clays are widespread over large areas — about 1,270 km². These clays belong to the terrigenous colloidal-sedimentary type and are genetically associated with the Boyarka formation of the upper Miocene. Currently, the unique Cherkasy deposit is being developed, particularly the Dashukivka area. The clays have varying composition and properties and are used for the production of ceramic products, drilling fluids, sorbents, and other purposes. Within the Cherkasy deposit, there are also preliminarily explored areas and occurrences of bentonite clays.
Graphite
Six graphite occurrences have been identified. Among them, the Pavlivka occurrence is the most promising in terms of graphite content and mining conditions. Other graphite occurrences, such as Mezhyrich, Sverdlykiv, Skaliv, Kamianchechiv, and Holubenkiv, have no industrial significance due to low graphite content. The Pavlivka occurrence is located near the village of Pavlivka Persha and is associated with a structural zone containing graphite-bearing gneisses and other rocks.
Granite, gneiss, migmatite
The region contains four registered deposits of decorative stone (granite): Bohuslav, Starobabanske, Tanske, and North-Tanske. The Bohuslav deposit is located near the city of Bohuslav and contains light-gray granite used for blocks and crushed stone. The Starobabanske deposit is located near the village of Stari Babany and contains gray and pinkish-gray granite for cut stone and facing slabs.
The Tanske deposit is located near the village of Tanske and also contains gray and pinkish-gray granite used for blocks and facing slabs. The North-Tanske deposit is located on the northern extension of the Tanske deposit and is currently being developed.
Raw materials for crushed stone and rubble stone production mainly come from deposits of granite, gneiss, and migmatite. Some deposits are actively mined, while others are conserved. These materials are used in railway construction, heavy concrete structures, and other construction projects.
Sand
Sand deposits in the region are associated with various deposits from the Paleogene, Neogene, and Quaternary systems. The sands are mostly fine- and medium-grained in structure, sometimes with clay content. Coarse-grained sands are rare. The largest sand extraction sites include Pishchanske, Synyavske, Yerkyvske, and Katerynopil II. The sands are used for construction mortars, as fillers in heavy concrete, and in road construction.
Groundwater
Cherkasy region contains deposits of fresh and mineral underground waters, including mineral radon springs in some cities. One deposit of mineral radon waters is located in the Bila Tserkva district and is associated with a deep aquifer and a high radon content. Another deposit is located in Zvenyhorodka and is operated by the “Radon” sanatorium. In addition, there are deposits of fresh groundwater such as Tarashchanske, Kaharlytske, and Umanske, which differ in depth and well yields.
Thus, Cherkasy region has significant potential for the use of its mineral resources in various sectors of the economy, which may lead to increased production, reduced import dependence, and regional development. It is important to ensure sustainable development and environmental protection during mineral extraction activities.
