Summary

Organic matter, present in some sediments, acts as the source for hydrocarbons and has been studied at great length, but organic-rich sediments from hypersaline environments are just beginning to be understood. Many types of organic matter from such restricted environments have been identified, and in this study their maturation pathways and products are being explored. By collecting biologically-identified organic matter produced within modern evaporative environments from a number of different marine and nonmarine settings and carrying out detailed geochemical examination of samples we are gradually beginning to understand these materials. The organic samples collected were from evaporative marine, sabkha, and lacustrine deposits, and have been subjected to two types of artificial maturation, hydrous and confined pyrolysis, over a fairly wide range of temperatures (1500 to 350[degrees]C). The biomarker products of these treatments are being analyzed and followed in great detail. Analyses of saturate and aromatic hydrocarbons as well as sulfur compounds in the original and the matured samples provide a comprehensive view of the biomarker assemblages associated with these different depositional environments at different stages of maturity. Infrared spectroscopy and Rock Eval pyrolysis of both the isolated kerogens from both the original and pyrolyzed samples has permitted us to clearly characterize the functional groupings on the one hand and the free hydrocarbons, the potential hydrocarbons, and the oxygenated compounds on the other hand. We have thus been able to demonstrate the potential of the organic matter associated with the different evaporitic environments to act as a good source for oil generation.
