Scientific paper
A discussion of the 7 tree-ring series presented by Kumagai and Fukao (KF) used as a cross-correlation (CC) analysis in detecting pattern-matching of short (less than 80 years) time series is presented. The authors believe that the KF's CCS are insufficient to support the conclusion that petrified trees in the Hachiya Formation record the emplacement chronology of Miocene volcanic deposits. The authors clarify the statistical setting of the KFs' paper by presenting evidence supporting an alternative interpretation that inferred pattern-matching among the 7 series is probably not significant, and may be erroneous. Lastly, several references on early Holocene/late-Glacial dendrochronology relevant to KF's paper are mentioned.
