PETROCHEMICAL CHARACTERISTICS AND GEODYNAMIC SITUATION FOR FORMING UPPER PRE-CAMBRIAN (VENDIAN) SANDSTONES OF THE SOUTH-WESTERN SKIRT FOR THE EAST-EUROPEAN PLATFORM
The types of supplying provinces and geodynamic conditions for sediment forming as well as a ratio difference for sandstones material constitution from the basic complexes of source sediments (rocks) basing on petrochemical characteristics are given on the example for Upper Vend sandy rocks for south-western skirt of the East-European platform (region of Dniester perikraton).
