This paper presents results of investigations on possibilities of finding periodicity related to solar activity changes in annual growth sequences of trees. The research materials were six chronologies based on subfossil oak trunks (so-called black oaks) coming from alluvial deposits of the Vistula river in the vicinities of Cracow. The analyzed chronologies cover the period of the last 4000 years...
This work presents results of studies on possibilities of finding periodicity related to solar activity changes in annual growth sequences of trees. The analyzed material were subfossil oak trunks (so-called black oaks) lifted from alluvial deposits of the Vistula river in the vicinity of Cracow, which had been felled and subsequently buried around 8000, 4600, 3500, 2000 and 1000 years ago. Treatment...
