The changes in chemical composition and properties of subfossil oak deposited in Holocene sediments

Original language description

The study deals with the influence of chemical composition changes on subfossil wood properties in comparison to recent wood in the conditions of the Czech Republic, in dependence on the specific geological sediments the wood was deposited in. Chemical constituents (including individual elements) were established in order to determine what type of fossilization proceeds in the specific geological conditions. As regards properties, attention focuses on density, shrinkage, compression strength parallel tograin and hardness. We ascertained that the proportions of ash and calcium in subfossil wood increase as well as the proportion of lignin which increases at the expense of polysaccharides. The differences in chemical composition cause differences in behaviour of wood, e.g. shrinkage increases or mechanical properties deteriorate. The results indicate that the influence of the environment in which the wood was deposited on the changes in chemical composition and thus mechanical propertie
