Samples of siliciclastic, organic rich, microbial laminated deposits from the brackish-water environment of the Puck Bay (Southern Baltic Sea) were analyzed by means of gas chromatography and mass spectrometry. The distribution of extractable hydrocarbon fraction was examined. GC-MS investigations revealed that there occur n-alkanes from C/sub 16/ to C/sub 35/, hopanoids and isoprenoids (pristane and phytane). In spite of a number of subfossilized cyanobacteria and microalgae in the composition of the n-alkane fraction, long-chain alkanes predominate. High contents of C/sub 22/ and C/sub 24/ alkanes; relative abundance and variety of hopanoids (two of which have not been described previously) seems to be better indicators of the presence of cyanobacteria and microalgae and of their biodegraded remains.
