Kerogen from the Green River shale was degraded by stepwise oxidation with alkaline potassium permanganate. Carboxylic acids were produced in high yield (70% based on original organic matter). These were converted to their methyl esters and analyzed using a gas chromatograph-mass spectrometer-computer system. The main products were unbranched aliphatic acids (C 8 -C 29 ), saturated dibasic acids (C 4 -C 17 ) and isoprenoid acids (C 9 , C 12 , C 14 -C 17 , C 19 -C 22 ); keto and aromatic acids were present in very small quantities. On the basis of these results, it is suggested that this kerogen consists of a "nucleus" of interconnected, long aliphatic methylene bridges to which unbranched and isoprenoid chains are attached. The branching points must be of a type that is susceptible to oxidative attack, alkaline hydrolysis, or both.
