OLD LINDEN AND POPLAR WOOD PUT INTO WORK The paper presents the results obtained in the study of new archaeometric and chemometric characteristics for old linden wood (Tillia cordata Mill.) and poplar wood (Populus robusta), put into work. Therefore, based on elemental chemical composition data, humidity, pH, ash and those related to wood extraction components, which are characteristics with low arteriometric potential, the chemometric characteristics with an archeometric value were evaluated. Samples used in this study, both linden and poplar wood, the following near-linear ratios were observed in the next reports: C/O, (C+H)/O, (C+H)/Norganic, pH/Humidity, Nmineral/Ash, extract in NaOH/extract in hot water and extract in ethyl alcohol/extract in ether, which can be used in establishing an archaeometric reference.
