Abstract
The percentages of aromatic carbon in several Lower Paleozoic black al um shales of the Baltoscandian, region have been determined by solid s tate high resolution nuclear magnetic resonance spectroscopy. In marke d contrast to the Estonian Middle Ordovician shale kukersite, the blac k shales have a much higher rank of maturation, and carbon aromaticity in the Cambrian shales exceeds 50 %. The overall structure of the org anic matter is similar to that found in typical samples of major US sh ales.
