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 ...

Spontaneous Transient Summit Uplift at Taftan Volcano (Makran Subduction Arc) Imaged Using an InSAR Common‐Mode Filtering Method

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We unambiguously document unrest at Taftan volcano. Summit uplift was detected using Interferometric Synthetic Aperture Radar time series and its timing tightly constrained applying a new common mode filtering method. Uplift started and ended gradually lasting 10 months (July 2023 to May 2024).

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.

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 ...

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 ...

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.

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.

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 ...

Probabilistic Seismic Hazard Assessment for United Arab Emirates, Qatar and Bahrain

Applied Sciences, 2020
A probabilistic seismic hazard assessment in terms of peak ground acceleration (PGA) and spectral acceleration (SA) values, for both 10% and 5% probability of exceedance in 50 years, has been performed for the United Arab Emirates, Qatar, and Bahrain. To

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 ...
