WebNov 20, 2024 · Three-dimensional (3D) seismic-reflection analysis of a major Miocene-to-Pleistocene (c. 19–2 Ma) clinoform succession of the central Taranaki Basin offshore New Zealand reveals two distinct intervals of downbuilding progradation (c. 7.5–6 Ma; and c. 4–2 Ma). Downbuilding clinoforms are of kilometre scale and characterized by straight upper … WebWe show that the margin’s Miocene clinoforms have recorded 22 cycles and 76 phases of eustatic changes over 8 Myr. While previous studies suggest a correspondence between 1.2 Myr obliquity modulation cycles and third-order sequences, our spectral analysis of the cyclicity of the eustatic events yields local spectral peaks at 25 Kyr and 40 Kyr ...

WebMay 16, 2024 · Since high sediment supply often results in steeper clinoforms [59,78], we expected that shorefaces in zones I and II would be steeper than eastern shorefaces. One explanation for the disparity between our observations and stratigraphic principles is that upper shoreface morphology in eastern Rockaway reflects human interventions at the ...
