Temporal changes in the internal stresses and pore pressures in a large-scale submarine mass transport deposit

open access: yesProgress in Earth and Planetary Science, 2018
We examined the temporal changes in the internal stresses and pore fluid pressures of a submarine mass transport deposit (MTD) in the Akkeshi Formation of the Upper Cretaceous–Paleocene Nemuro Group, eastern Hokkaido Island, Japan.

Sedimentation and mobility of PDCs: a reappraisal of ignimbrites’ aspect ratio

open access: yesScientific Reports, 2017
The aspect ratio of ignimbrites is a commonly used parameter that has been related to the energy of the parent pyroclastic density currents (PDCs). However this parameter, calculated as the ratio between the average thickness and the average lateral ...

Metal Preservation and Mobilization in Sediments at the TAG Hydrothermal Field, Mid‐Atlantic Ridge

open access: yesGeochemistry, Geophysics, Geosystems, 2023
At the Trans‐Atlantic Geotraverse hydrothermal field, metalliferous sediments cover extinct hydrothermal mounds and the surrounding seafloor. Here, we report the morphological, mineralogical and geochemical processes that deposit these sediments ...

Representative Dynamic Accumulation of Hydrate-Bearing Sediments in Gas Chimney System since 30 Kyr BP in the QiongDongNan Area, Northern South China Sea

open access: yesJournal of Marine Science and Engineering
A stratigraphic complex composed of mass transport deposits (MTDs), where the gas occurrence allows for the formation of a gas chimney and pipe structure, is identified based on seismic interpretation in the QiongDongNan area of the northern South China ...

Intensification of technological processes in drilling and blasting operations during open-cut mining in Kyzylkum region [PDF]

open access: yes, 2018
Purpose. It is found that for long term standing, the pit bench profile is close to the boundary of the disturbed zone. Therefore, long stability of the bench can be estimated in respect to the size of the disturbed area and the boundary of residual ...

Incorporation of substrate blocks into mass transport deposits: Insights from subsurface and outcrop studies

open access: yesThe Depositional Record
Mass movements are common on the continental slope, affecting not only the subsequent sea floor morphology but often substantially modifying the underlying deposits.

Possible climate preconditioning on submarine landslides along a convergent margin, Nankai Trough (NE Pacific)

open access: yesProgress in Earth and Planetary Science, 2017
Submarine landslides are major agents of sediment mass transfer from the shallow to deep sea. Due to their rapid emplacement and tsunamigenic potential, such landslides are significant geohazards for society and off- and on-shore infrastructure.

Basin-wide erosion and segmentation of the Plio-Pleistocene forearc basin in central Japan revealed by tephro- and biostratigraphy

open access: yesProgress in Earth and Planetary Science, 2023
The basement of the Tokyo metropolitan area consists of the Miocene–Pleistocene forearc basin fills that are well exposed around Tokyo Bay, especially on the Miura and Boso peninsulas.
