Adakitic magmatism, a window to evolution on tectonic and mineralization in eastern Iran

Journal of Economic Geology, 2023
In this research, geochemical data from 314 samples of volcanic and intrusive rocks with adakitic or adakite-like affinity reported from eastern Iran have been studied, these rocks are often known with Sr>400 g/ton and ...

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 ...

On the magmatic record of the Makran arc, southeastern Iran: Insights from zircon U‐Pb geochronology and bulk‐rock geochemistry

Geochemistry, Geophysics, Geosystems, 2014
Twenty‐one magmatic rocks were analyzed for major and trace elements, and a subset of them for Sr‐Nd isotopes and zircon U‐Pb isotopes, to constrain magma genesis and tectonic evolution of the Makran arc, southeastern Iran.

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 ...

Fault-based probabilistic seismic hazard assessment of the eastern Makran subduction and the Chaman transform fault, Pakistan: Emphasis on the source characterization of megathrust

, 2021
Seismic source characterization (SSC) for probabilistic seismic hazard assessment (PSHA) in regions characterized by subduction megathrust involves a considerable ambiguity.

Chromian spinel geochemistry as a petrogenetic indicator in the chromitites and peridotites of the Bajgan Complex, Western Makran [PDF]

پترولوژی
IntroductionEconomic chromite deposits are very common in ophiolite belts. These deposits usually occur in the uppermost horizons of the ophiolite mantle sequence or within the ultramafic cumulitic rocks at the base of the crustal sequence (González ...

Sensitivity Analysis of the Thermal Structure Within Subduction Zones Using Reduced‐Order Modeling

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract Megathrust earthquakes are the largest on Earth, capable of causing strong ground shaking and generating tsunamis. Physical models used to understand megathrust earthquake hazard are limited by existing uncertainties about material properties and governing processes in subduction zones.

Geomorphological, sedimentological and structural signals of deformation in a silent subduction zone: an investigation of the Makran (Iran)

, 2019
The Makran subduction zone of southeastern Iran has not experienced a megathrust earthquake in recent history, yet, the presence of uplifted coastal morphologies indicate that the margin is still tectonically active. In this work, we study three types of

80 years of research on tsunamigenic earthquakes in the Makran subduction zone (1945–2025): a review- part B: tsunamis in the MSZ

Frontiers in Earth Science
The Makran Subduction Zone (MSZ) is a tectonically active margin with a documented history of tsunamis that have repeatedly impacted coastal communities along the northern Arabian Sea.
