Determination of stress state in deep subsea formation by combination of hydraulic fracturing in situ test and core analysis: A case study in the IODP Expedition 319 [PDF]

open access: yes, 2013
[1] In situ test of hydraulic fracturing (HF) provides the only way to observe in situ stress magnitudes directly. The maximum and minimum horizontal stresses, SHmax and Shmin, are determined from critical borehole pressures, i.e., the reopening pressure

Possible Jurassic age for part of Rakaia Terrane: implications for tectonic development of the Torlesse accretionary prism [PDF]

open access: yes, 2001
Greywacke sandstone and argillite beds comprising Rakaia Terrane (Torlesse Complex) in mid Canterbury, South Island, New Zealand, are widely regarded as Late Triassic (Norian) in age based on the occurrence of Torlessia trace fossils, Monotis, and other ...

Fluids in accretionary prisms

open access: yesEos, Transactions American Geophysical Union, 1990
Subduction zones are the most dynamic tectonic environments on the face of Earth. Most subduction zones are submarine and at many, large accretionary prisms are formed of sediments scraped from the subducting oceanic lithosphere. These prisms grow in a water‐saturated environment; consequently, their tectonic, thermal and chemical evolution is strongly

A new method for the empirical conversion of logging data to clay mineral fraction in the Nankai accretionary prism

open access: yesEarth, Planets and Space, 2020
Sediment lithology, especially the clay mineral fraction, is basic geologic information, which is important for understanding faulting and evolutionary process of the accretionary prism.

The First D/V Chikyu IODP Operations: Successful Logging and Coring During NanTroSEIZE Stage 1 Expeditions [PDF]

open access: yesScientific Drilling, 2008
The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) is a multi-expedition IODP drilling project aimed at drilling, coring, logging, and instrumenting the seismogenic zone of an active subduction margin , in a region thought to generate megathrust

Thermal Conductivity Profile in the Nankai Accretionary Prism at IODP NanTroSEIZE Site C0002: Estimations From High‐Pressure Experiments Using Input Site Sediments

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Depth profiles of sediment thermal conductivity are required for understanding the thermal structure in active seismogenic zones. During the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE), a scientific drilling project of the International Ocean

Structural control and system-level behavior of the seismic cycle at the Nankai Trough

open access: yesEarth, Planets and Space, 2020
The Nankai Trough in Southwest Japan exhibits a wide spectrum of fault slip, with long-term and short-term slow-slip events, slow and fast earthquakes, all associated with different segments down the plate interface.

Three-layer structure of the Carpathian sedimentary prism from the results of seismic migration on the PANCAKE and RomUkrSeis WARR profiles

open access: yesГеофизический журнал, 2022
The method of finite-difference migration of reflected/refracted waves, applied to the PANCAKE and RomUkrSeis WARR seismic profiles, made it possible to form wave images of sedimentary layer and crystalline basement under the Carpathian orogen to a ...

Stages of Gas-Hydrate Evolution on the Northern Cascadia Margin [PDF]

open access: yesScientific Drilling, 2006
Natural gas hydrate occurs beneath many continental slopes and in arctic permafrost areas. Recent studies have indicated that the largest deposits of gas hydrate might lie in nearly horizontal layers several hundred meters beneath the seafloor of ...
