Source Potential of Triassic Sediments in the Southernmost Moesian Platform Central Zone

P283 SOURCE POTENTIAL OF TRIASSIC SEDIMENTS IN THE SOUTHERNMOST MOESIAN PLATFORM CENTRAL ZONE Introduction 1 Most of the oil and gas economic discoveries in Bulgaria are located in the southernmost Moesian platform part along the transition zone to southern platform margin. Five of the most significant economic fields are situated in the Southern Moesian Platform central zone (Fig. 1-C). They are related with various Mesozoic sedimentary formations and structural zones but the major reserves are concentrated in the Anisian carbonates (Doyren Fm) and Lower Jurassic basal clastics (Kostinska Fm.). Long time the origin of the hydrocarbons in the fields was
