Stratigraphic and sedimentological aspects of ichnofabric analysis

Trace fossils are one of the paleontological groups that could be used for solving complex geological problems. Trace fossils represent the sedimentological structures, produced by living organisms in the mass of sediment. This complex, both paleontological and sedimentological, nature of ichnofossils results in serious limiiations for sedimentary sequences stratigraphic dissection, correlation and age determination. This paper demonstrates the main aspects of trace fossils and appliance of ichnofabric analysis for solving sedimentological and stratigraphic probl ems.
