Abstract:
Coal and coaly - claystone are founded in Oligocene strata in most well block 12 Nam Con Son Basin. Organic geochemical analysis and organic petrology show that coal and coaly - claystone are rich in organic matter, containing mainly kerogen group III (vitrinite maceral) and kerogen group I - II (Liptinite maceral: alginite, sporinite, bituminite), mainly gas prone. Organic materials in sediments are derived from higher plants growing in terrestrial environments. Oligocene coal - bearing strata in the block 12 are in the stage of maturing and in oil window
