Details of the three-dimensional morphology ichnofossil Phycosiphon incertum collected from deposits on submarine slopes are reconstructed by processing a series images obtained polished sections samples. Samples were mudstone around slump scar in Paleocene Shiomi Formation, northern Japan, which is characterized occurrence scars. The meandering tube with flattened ellipse cross section. tubes plane oblique to bedding surfaces and aligned along same direction at both interior exterior scar....
Nine ammonoid species are reported from the Maastrichtian Senpohshi Formation exposed along western coast of Akkeshi Bay, eastern Hokkaido, and their respective chronologic assignments discussed on basis a previous magnetostratigraphic study. Pachydiscus flexuosus occurs in lower middle parts formation (= polarity chron C31n, i.e., to upper Maastrichtian). Gaudryceras makarovense, Anagaudryceras matsumotoi Diplomoceras cf. notabile P. as well occur part (middle The uppermost probably C30n,...
Abstract This study investigates overpressure evolution and its relationship to the spatial temporal changes in sedimentation rate passive continental margin of offshore Suriname. We analysed well data estimate pore pressure at locations interpret relevant overpressure‐generating mechanisms. Three‐dimensional basin modelling was performed reconstruct area. The indicated disequilibrium compaction as main overpressure‐forming mechanism. results a variation caused cycles formation region....
ABSTRACT: A better understanding of geomechanical properties mudstone caprocks over a targeted storage area is crucial for effective geological carbon storage. However, it difficult to evaluate lateral variations in detail because primary subsurface information obtained through appraisal wells limited most cases. Utilization onshore outcrops as an analogue geology enables us overcome limitation data. The present study investigated semiconsolidated mudstones collected from with precise...
In petroleum exploration, it is crucial to understand the origin of CO2 in reservoirs avoid CO2-rich reservoirs. The gas isotopic signature a clue its origin; however, not uncommon that such geochemical data are lacking or limited. This case with offshore Sarawak, Malaysia, where cannot be determined as mantle- carbonate-origin because lack helium isotope data. this study, area was examined using simplified migration modeling approach considered source areas for and scenarios pathways after...
