BURIAL AND THERMAL HISTORY MODELLING OF THE EDIACARAN SUCCESSION IN WESTERN AND SW UKRAINE AND MOLDOVA

N. Radkovetsa*, P. Kosakowskib, J. Rauballc and A. Zakrzewskib

The Ediacaran (Upper Neoproterozoic) succession in west and SW Ukraine and Moldova rests on a Cryogenian succession or basement.The succession is exposed at the surface along the southern margin of the Ukrainian Shield and dips to the SW towards the Carpathian Overthrust; where burial depths are sufficient, it is mature for oil and gas generation. The Ediacaran succession is made up of terrigenous siliciclastics ranging from conglomerates and sandstones to siltstones and mudstones, and includes a shale interval (the Kalus Beds) which may have source rock potential. Organic matter in the Kalus shales includes Vendotenides sp. (colonial bacteria) together with amorphous OM. This paper presents a study of the Kalus Beds and is based on data from surface and core samples and thin sections, and the results of Rock-Eval pyrolysis and reflectance analyses.TOC contents in the Kalus shales are in general
