It was determined that approximately four times more bitumen-free organic matter is associated with silicate minerals than with carbonate minerals. The major structural constituent of the various filtrate fractions was paraffinic compounds. However, spectroscopic analysis indicated relatively larger concentrations of olefins and branched paraffins with the acid/ether extracted organics associated with the carbonate minerals. The silicate mineral matrix was determined to interact with a bitumen-free organic interfacial layer containing relatively more esters, ketons, and long chain aliphatic compounds. In addition, trapping of bitumen-free organic matter was observed, particularly in the case of the carbonate mineral matrix. These interactions involving carbonate and silicate minerals are descriptive of the binding forces in Green River oil shale as they pertain to the interfacial layer between kerogen and the inorganic mineral matrix.
