The model of dynamics of alternating landscape complexes on the basis of analyzing the organic remnants revealed in palynologic preparations is proposed in the form of the generalized geomorphologic profile with consideration for changing the processes of sedimentation and biota alternation in transgressive-regressive cycles. The established facies complexes of plant remnants (including spores, pollen, algae, acritarch, mushrooms, bacteria, and others) from Paleozoic deposits hold a definite position within a lateral series of facies. As a result, the position of a shore line and the most productive source rocks on the profile is distinctly determined on the composition of organic remnants. It is of great importance in searches for oil and gas.
