Upward delamination of Cascadia Basin sediment infill with landward frontal accretion thrusting caused by rapid glacial age material flux [PDF]

, 2004
The Cascadia convergent margin is a first-order research target to study the impact of rapid sedimentation processes on the mechanics of frontal subduction zone accretion.

Slab Tearing and Recycled Continental Sediments in the Lithospheric Mantle: Geodynamic Insights From Miocene Alkaline Rocks of the Tangra‐YumCo Rift, Southern Tibet

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Mantle metasomatism is a common phenomenon in convergent margins; however, metasomatism by subducted sediments and their role in alkaline magma generation remain poorly understood. Alkaline rocks from the Tangra‐YumCo rift (TYR) in southern Tibet show a unique geochemical composition among post‐collisional volcanic rocks of the Lhasa terrane ...

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).

Estimation of size of megathrust zone in the Makran subduction system by thermal modelling

Geophysical Journal International, 2021
SUMMARYTo estimate the maximum possible size of megathrust earthquakes, we calculate the thermal structure along two profiles in west and east Makran subduction zone by solving the steady-state 2-D energy equation. For the western profile, we derive the slab geometry from a recent receiver function study along IASBS (Institute for Advanced Studies in ...

A CATALOG OF TSUNAMIS IN THE INDIAN OCEAN [PDF]

Science of Tsunami Hazards, 2006
A catalog of about ninety tsunamis in the Indian Ocean has been prepared from 326 BC to 2005 AD. In the nineteenth and twentieth centuries tsunamis have occurred once in three years or so.

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 ...

Petrogenetic and tectonic aspects of collisional granitoids from the Sanandaj-Sirjan Belt of Iran [PDF]

, 2012
The Sanandaj-Sirjan granitoids (SSG) in western Iran are composed mainly of granite, granodiorite and tonalite. Chemically the rocks are peraluminous and metaluminous, and show S-and I-type characteristics.

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 ...

Imaging the seismic structure of the western Makran Subduction Zone

Geophysical Journal International
SUMMARY We analyse data from 48 seismic stations located in the western part of the Makran Subduction Zone to gain a detailed knowledge of the crustal and uppermost mantle structure in that region. The Makran is a flat subduction zone with a very thick accretionary wedge.

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

, 2015
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 ...
