Assessment of gas hydrate saturations in the Makran accretionary prism using the offset dependence of seismic amplitudes

, 2010
We estimate the saturations of gas hydrate and free gas based on measurements of seismic-reflection amplitude variation with offset (AVO) for a bottom-simulating reflector coupled with rock-physics modeling.

Stratigraphic structural and geochemical data on the Durkan Complex (Makran Accretionary Prism, SE Iran): constraints for its interpretation as a Late Cretaceous tectonically disrupted seamount chain.

, 2021
The Makran Accretionary Prism (SE of Iran) is part of the Alpine-Himalayan orogenic system, and it is still associated with active subduction. The Makran results from the Cretaceous to resent-day convergence between the Arabian and Eurasian plates that ...

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

, 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

Controls on the geometry and evolution of thin-skinned fold-thrust belts, and applications to the Makran accretionary prism and Indo-Burman Ranges [PDF]

, 2019
The formation of fold-thrust belts at convergent margins is a dynamic process. Accretion of weak sediments to the front of the overriding plate results in crustal thickening and continued flexural subsidence of the underthrusting plate. Fold-thrust belts

Appraisal of gas-hydrate/free-gas from VP/VS ratio in the Makran accretionary prism

, 2008
Existence of gas-hydrate in the marine sediments elevates both the P- and S-wave seismic velocities, whereas even a small amount of underlying free-gas decreases the P-wave velocity considerably and the S-wave velocity remains almost unaffected. Study of

Rare earth elements of ROV sample GeoB12338-2 from the Makran accretionary complex

, 2010
Authigenic carbonates forming at an active methane-seep on the Makran accretionary prism mainly consist of aragonite in the form of microcrystalline, cryptocrystalline, and botryoidal phases. The d13Ccarbonate values are very negative (-49.0 to -44.0 per

Effective medium modeling to assess gas hydrate and free-gas evident from the velocity structure in the Makran accretionary prism, offshore Pakistan

, 2008
Seismic properties of sediments are strongly influenced by pore fluids. Stiffness of unconsolidated marine sediment increases with the presence of gas hydrate and decreases with the presence of gas.
