LITHOLOGY OF YAMPIL SANDSTONES OF THE PODIL BASIN OF UKRAINE

The article presents the results of lithological and mineralogical studies and the analysis of structural and textural features of the Yampil Sandstones of the Podil Basin of Ukraine. In the section of the sandstones, a two-member structure is distinguished - limestone, which occurs in the upper part of the Yampil beds and block stone, which is located below the limestone. The total thickness of the Yampil beds in the most complete sections is 30—35 m. In the total volume of the section of the Yampil layers for the study area, the share of limestone is approximately 8 —11 %. In block sandstones, the main minerals are quartz (65—82 %); feldspars (15—40 %); secondary (3—6%) and include dark and light micas, pyrite, fluorite, galena, sphalerite, marcasite; accessory (1—1.5 %) include tourmaline, almandine, sphene, zircon, monazite. According to textural features, they are divided into: massive-homogeneous, banded, spotted, and landscape varieties. The main disadvantages of blocky sandstones are their relatively high porosity and water absorption.

Keywords: Podillia, Ediacaran, Yampil sandstones, mineral composition.
