Subsurface Gaseous Hydrocarbons and Carbon Dioxide Recorded During the Trans‐Amazon Drilling Project (TADP) in the Acre Basin, Western Amazon

Geofluids, Volume 2025, Issue 1, 2025.
The Trans‐Amazon Drilling Project (TADP) drilled a sequence of claystones, siltstones, and sandstones in the Acre sedimentary basin, reaching a final depth of 923 m. This study characterizes the occurrence and compositional variation of light gaseous hydrocarbons detected using the online gas analysis (OLGA) monitoring system deployed during drilling ...

The Self‐Calibrating Tilt Accelerometer: A Method for Observing Tilt and Correcting Drift With a Triaxial Accelerometer

Earth and Space Science, Volume 11, Issue 11, November 2024.
Abstract We present observations from two field deployments of a calibrated tiltmeter that we name the Self‐Calibrating Tilt Accelerometer (SCTA). The tiltmeter is based upon a triaxial quartz crystal accelerometer; the horizontal channels measure tilt and are periodically rotated into the vertical to obtain a measurement of the acceleration of gravity.

IODP Expedition 338, Hole C0022A - Well Logging Data

, 2021
Logging data are measurements of physical properties of the formation surrounding a borehole, acquired in situ after completion of coring (wireline logging) or during drilling (Logging-While-Drilling, LWD). The range of data (resistivity, gamma radiation,

Sediment Provenance Along the Middle Miocene‐Pleistocene Nankai Subduction Zone From Sediment Transport to Accretion: Implications for Stratigraphy in the Accretionary Prism

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 8, August 2024.
Abstract Based on U‐Pb dating of zircon crystals and petrographic analysis, this study provides new insights into the paleogeographic and accretion evolution along SW Japan. Our data are consistent with an older submarine fan identified from drilling in the Shikoku Basin (Kyushu Fan ∼14.7–12.2 Ma), having a mixed sand provenance from the paleo‐Yangtze ...

Frontal Thrust Ramp‐Up and Slow Earthquakes Due To Underthrusting of Basement High in the Nankai Trough

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 7, July 2024.
Abstract Recently, integrated geophysical‐geological surveys in the Nankai subduction zone in Japan have revealed that slow earthquakes repeatedly occur beneath the outer wedge of the forearc. During December 2020 to February 2021, clustered slow earthquakes propagated around the frontal thrust of the accretionary wedge.

Geometrical dependence on the stress and slip tendency acting on the subduction megathrust of the Nankai seismogenic zone off Kumano

Progress in Earth and Planetary Science, 2019
We assess the dependence of megathrust geometry near the updip edge of the Nankai seismogenic zone according to the slip tendency of the megathrust based on a reprocessed 3D PSDM seismic volume image and International Ocean Discovery Program (IODP ...

Geochemical constraints on the temperature and timing of carbonate formation and lithification in the Nankai Trough, NanTroSEIZE transect [PDF]

Geochimica et Cosmochimica Acta, 2017
Information about diagenetic processes and temperatures during burial of sediments entering the subduction zone is important for understanding changes in physical properties and seismic behavior during deformation. The geochemistry of authigenic carbonates from accretionary prisms can serve as proxies for conditions during carbonate cementation and ...
