Hydrocarbon and azaarene concentrations and compositions vary systematically in sixteen western Washington coal samples ranging in rank from lignite to anthracite. Subbituminous and bituminous samples within a vitrinite reflectance range of 0.4% to 0.8% R/sub 0/ contain hydrocarbon suites and azaarenes whose compositions correspond to those found in selected Puget Sound and Lake Washington sediments as well as coal particles seived from a Puget Sound core. Dominant coal components include pristane, C/sub 19/ and C/sub 20/ tricyclic diterpanes, retene, methylated chrysenes and picenes, tetrahydrochrysenes, hydropicenes, and either 1- or 3-methylphenanthrene relative to other methylphenanthrenes. The C/sub 19/ and C/sub 20/ diterpanes are limited in their geologic occurrence and serve as distinctive fossil markers. These coals generate an overall lipid signal distinct from other fossil sources including street runoff and municipal sewage discharges. Thus, molecular markers demonstrate the transport of specific local coals to aquatic sediments in adjacent drainage basins resulting from erosion and mining activity. 38 references, 4 figures, 2 tables.
