20.500.12556/RUL-177618 Subfossil Abies alba stems from the 5th millennium BC Subfosilna debla navadne jelke iz 5. tisočletja pr. Kr. Subfossil stems of silver fir (Abies alba) trees buried in wet soil were discovered in the Čadrg area above Tolmin, Slovenia. Dendrochronological analysis showed that the five studied trees were large and old, having grown in optimal conditions (maximum diameter and age over 80 cm and 187 years). The radiocarbon dates of the last tree rings below the bark of three trees were 4660 ± 64 cal BC (2σ), 4524 ± 64 cal BC (2σ), and 4272 ± 46 cal BC (1σ), and two tree-ring chronologies for the periods 4831–4524 and 4367–4272 cal BC were compiled. Light microscopy confirmed that the wood is mostly fairly well preserved, but there are areas in the wood where the cell walls are in various stages of decay caused by erosion bacteria. We discuss the significance of the subfossil trees for palaeoecology, archaeology, at the end of the Neolithic and the beginning of the Copper Age and to prolong the silver fir chronologies for Slovenia and Central Europe. Na območju Čadrga nad Tolminom so odkrili subfosilna debla navadne jelke (Abies alba), zakopana v mokrih tleh. Dendrokronološke raziskave so pokazale, da je bilo 5 raziskanih dreves velikih in starih in da so rasla v ugodnih razmerah (največji premer in starost nad 80 cm in 187 let). Radiokarbonski datumi zadnjih branik pod skorjo 3 dreves so bili: 4660 ± 64 kal. pr. Kr. (2σ), 4524 ± 64 kal. pr. Kr. (2σ) in 4272 ± 46 kal. pr. Kr. (1σ). Sestavljeni sta bili tudi dve kronologiji širin branik za obdobji okoli 4831–4524 pr. Kr. in 4367–4272 kal. pr. Kr. Svetlobna mikroskopija je potrdila, da je subfosilni les razmeroma dobro ohranjen, vendar ima območja, kjer so celične stene v različnih fazah bakterijskega razkroja. Predstavljamo pomen subfosilnih jelk za paleo-ekologijo, arheologijo, opredeljeno s koncem mlajše kamene dobe in začetkom bakrene dobe, ter za podaljšanje kronologij jelke v Sloveniji in srednji Evropi. navadna jelka = Abies alba Čadrg Slovenija subfosilni les dendrokronologija radiokarbonsko datiranje svetlobna mikroskopija 5. tisočletje pr.
