Transfer of Strontium and Carbon From Subducting Sediment Into the Leading Edge of the Mantle Wedge

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Carbon mobilization at subduction zones can be constrained by focusing on Sr as a proxy, as Sr readily substitutes for Ca—a major cation in the crystal structures of carbonates. Unmelted high/ultrahigh pressure (HP/UHP) pelitic metasediments exhumed from less than 100 km depth along the slab‐mantle interface show loss of Sr and retention of ...

REE distribution and enrichment of drainage point sediments from Makran and Lasbela, Pakistan

Kuwait Journal of Science
Rare Earth Elements (REEs) are mobile during weathering and their distribution is susceptible to both natural and anthropogenic influences. Four major drainage points in the Makran and Lasbela areas were selected for sampling to examine their REE ...

Interseismic strain accumulation along the western boundary of the Indian subcontinent [PDF]

, 2012
Despite an overall sinistral slip rate of approximately 3 cm/yr, few major earthquakes have occurred in the past 200 years along the Chaman fault system, the western boundary of the India Plate with the Eurasia Plate.

Geodynamics of Long‐Term Indian Continental Subduction and Indentation at the India‐Eurasia Collision Zone

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract The India‐Eurasia convergence is a long‐term, ongoing process despite the continental collision and associated velocity reduction from ∼15 to 20 cm/yr in the Late Cretaceous‐earliest Eocene to ∼4–5 cm/yr (since ∼40 Ma). Previous studies that impose Indian plate motion imply an external force driving long‐term convergence, continental ...

Tsunami and the effects on coastal morphology and ecosystems: A report [PDF]

, 2012
Tsunamis are one of the most destructive natural hazards that affect the coastal areas. Tsunami waves that impact the coast with enormous energy are capable of destroying the objects on the coast and re-shaping the coastal geography, geomorphology and ...

Subduction tractions and vertical axis rotations in the Zagros–Makran transition zone, SE Iran: the 2013 May 11 Mw 6.1 Minab earthquake [PDF]

The source parameters and slip distribution of the 2013 May 11 Mw 6.1 Minab earthquake are studied using seismology, geodesy and field observations. We observe left-lateral strike-slip motion on a fault striking ENE–WSW; approximately perpendicular to ...

Inferring Tectonic Plate Rotations From InSAR Time Series

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Interferometric Synthetic Aperture Radar (InSAR) provides constraints on lithospheric kinematics at high spatial resolution. Interpreting InSAR‐derived deformation maps at continental scales is challenged by long‐wavelength correlated noise and the inherent limitation of measuring relative displacements within the data footprint.

Evolving Sediment Structure and Lithospheric Architecture Across the Indo‐Burman Forearc Margin From the Joint Inversion of Surface‐ and Scattered‐Wave Seismic Constraints

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The Indo‐Burman subduction zone represents a global endmember for extreme sediment accretion and is a region characterized by ambiguous tectonic structure. The recent collection of broadband seismic data across the Indo‐Burman accretionary margin as part of the Bangladesh‐India‐Myanmar Array (BIMA) experiment provides an opportunity to ...

Crustal deformation analysis in Zagros and Makran zones, based on GPS permanent network data

Contributions to Geophysics and Geodesy, 2020
We present an analysis of strain based on the evaluation of crustal deformation in Zagros and Makran, which has implications in terms of the dynamics of the study area.
