Tectonostratigraphy of the Jurassic accretionary prisms in the Sikhote-Alin region of Russian Far East [PDF]

open access: yesScientific Reports, 2021
We propose a scheme to subdivide the Samarka terrane, a Jurassic accretionary prism fragment, into tectonostratigraphic complexes. This subdivision provides a basis to study these formations and map them on a medium- to large-scale.

Characteristics of High Saturation Hydrate Reservoirs in the Low-Angle Subduction Area of the Makran Accretionary Prism

open access: yesFrontiers in Earth Science, 2022
To delineate the spatial distribution of high saturation gas hydrate reservoirs in the low-angle subduction areas of the Makran Accretionary Prism, we conducted seismic data interpretation and impedance inversion of gas hydrates in the Makran ...

The topographic signature of temperature-controlled rheological transitions in an accretionary prism [PDF]

open access: yesSolid Earth, 2022
The local topographic slope of the accretionary prism is often used together with the critical taper theory to determine the effective friction on subduction megathrust.

Mechanical Weakness of the Nankai Accretionary Prism: Insights From Vp Measurements of Drill Cuttings

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The relationship between P‐wave velocity (Vp) and unconfined compressive strength (C0) can be used to estimate in situ rock strength and stresses at depth in subduction zones.

A-type granites induced by a breaking-off and delamination of the subducted Junggar oceanic plate, West Junggar, Northwest China

open access: yesChina Geology, 2022
The A-type granites with highly positive εNd(t) values in the West Junggar, Central Asian Orogenic Belt (CAOB), have long been perceived as a group formed under the same tectonic and geodynamic setting, magmatic sourceq and petrogenetic model. Geological

Deformation-enhanced diagenesis and bacterial proliferation in the Nankai accretionary prism [PDF]

open access: yesSolid Earth, 2021
Understanding diagenetic reactions in accreted sediments is critical for establishing the balance of fluid sources and sinks in accretionary prisms, which is in turn important for assessing the fluid pressure field and the ability for faults to host ...

Characteristics of major and trace elements in surface sediments of the Makran Accretionary Prism, Pakistan and their implications for natural gas hydrates

open access: yesChina Geology, 2021
To accurately identify the natural gas hydrates (NGH) in the sea area of the Makran Accretionary Prism, Pakistan, this paper presents the testing and analysis of major and trace elements in sediment samples taken from two stations (S2 and S3) in the area

Structural and tectonic evolution between Indo-Myanmar ranges and central Myanmar basin: Insights from the Kabaw Fault

open access: yesGeosystems and Geoenvironment, 2023
The Kabaw Fault is a north-south trending arcuate suture zone formed between the accretionary prism of the Indo-Myanmar Ranges (IMR), and the Central Myanmar Basin (CMB). The lineament of the Kabaw Fault is defined as a stratigraphic contact zone between

Diapir structure and its constraint on gas hydrate accumulation in the Makran accretionary prism, offshore Pakistan

open access: yesChina Geology, 2020
: The Makran accretionary prism is located at the junction of the Eurasian Plate, Arabian Plate and Indian Plate and is rich in natural gas hydrate (NGH) resources.

Viscous Accretionary Prisms: Viscoelastic Relaxation of the Makran Accretionary Prism Following the 2013 Baluchistan, Pakistan Earthquake [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2018
AbstractGeodetic observations of postseismic transients following earthquakes commonly help to inform the rheology of the lower crust and mantle, frictional properties of faults, and the kinematics of deformation across the earthquake cycle. Here we use interferometric synthetic aperture radar time series observations of postseismic deformation ...
