Transition probabilities from both core descriptions and wireline-log data from the Miocene section of Ocean Drilling Program Leg 123 Site 765 are examined. The data cover 270 m of section dominated by carbonate turbidites with varying silica content. Although the significant transitions do not echo the "classic" Bouma sequence, statistically significant cycles and pair-oscillation appear to be common when substitution of facies is taken into account. The sequence is zoned using both visual core-description and minimum-variance zonation of the wireline data. Significant transition probabilities are calculated, and syntaxes developed for both data sets. Syntactic pattern recognition is conducted using the wireline-log data to map the completeness of the section. These analyses support the hypothesis that the low average sedimentation rate during the Miocene (2 cm/k.y.) is more likely a result of sediment starvation or bypassing than active erosion, with its concomitant disturbance of regular and significant cycles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
