For the last years the typical «worm) layers of regional distribution and quite definite stratigraphical position are found in the deposits of low carbon in the West Donbas. They are met in the deposits of the carboniferous samarium suite in subzone C rg2, of the vise layer and form roof or soil of the carbon strata. The traces of the representatives of other fauna except the worm passages are absent in the «worm» layers whereas above and below the «worm) layer they are met. The latter is indicative of the specific conditions of sediment formation which periodically appeared in the carboniferous thickness of the upper vise. These conditions were not only unfavourable but harmful for the vital activity of a number of organisms. Worm horizons in the carboniferous thickness of the upper vise can be used with the lithological peculiarities of the deposits for interpretation of the problems of an organism interconnection with the environment in the geological past and for the solution of «small stratigraphy» problems. The article deals with the description of the morphology of the worm passages in worm rocks, environment and conditions of their vital activity. The petrographic composition is presented of the material, enclosing and filling the passages. |
