Paper Abstract

For the last few years there have been a lot of publications in geological literature on the problem of formation of morphologically unique fine fibrous kerites, found in one of the objects of kamera pegmatites of Volyn (1800 - 1750 mln. years). According to the opinion of all researchers who deal with them, they are an excellent example of a biogenic, highly constructive carbon substance. The meeting of objectives set was carried out by means of the study of ultra-thin section and replicas of kerite cryofractures under high resolution electronic microscope. The similarity of fine structured fibrous kerite of Volyn (KV) to prokaryotic microorganisms is proved by availability in KV of clearly exposed cellular ultrastructures: multilayered cell wall, cross septa and cytoplasmatic membrane and `intracytoplasmic' inclusions. Fatty acids obtained from kerites contain a number of components typical of prokaryotic microbial community. Suggestions were made on the formation of fibrous Volyn's kerites as a result of mummification of the cyanobacterial mat components from freshwater thermal spring of moderate temperature. Thus, the detailed fine structure of microfossils and their fatty acid composition can be used to support evidence of biogenic origin of the bacteriomorphic elements in paleo- and space objects.
