The Land-Marsh Stage of Plant Resins Fossilization
Matsui V. M.
Summary:
The paper analyzes the Dniprobas’ natural features and conditions of resins fossilization in the early Middle Eocene. The land-marsh stage is a natural historical interaction process of biochemical, geochemical and physical factors in the stage of gum-resins formation and their burying in the underlayer of “amber” forests, intermittent lakes and swamps. The processes of weathering and oxidation of resin took place simultaneously with their drying and hardening; resin diagenesis occurred at the stage of peat and coal formation processes in high humidity and poor oxygen conditions. Under these conditions, the soil formation in the Dniprobas changed by bogging and peat formation. The recycled origin of amber-succinite productive layer by erosion of buchak paleopeatbogs that contain protoamber is a proven fact. Recommendations are given for the prediction of placer deposits of amber-succinite.
