Variations in Event‐Bed Thickness‐Frequency Distributions Near Volcanic Islands: Indicators of Varied Geological Processes by Yu‐Chun Chang, José C. F. Kling, Julie C. Schindlbeck‐Belo, Neil C. Mitchell, Kan‐Hsi Hsiung, Toshiya Kanamatsu

“…The reliability of this analytical approach depends on high‐quality sediment recovery, as drilling‐related disturbances may obscure primary depositional signals. Beyond stratigraphic characterization, the method shows broader potential for identifying the provenance of volcanic glass shards through geochemical comparisons and for evaluating the statistical compatibility of data sets from neighboring sites, ensuring sufficient sample size for robust integrated analyses.…”
