Seismic images of crust and upper mantle in Central Iran (from Jiroft to Ashtian) via teleseismic waves

open access: yesContributions to Geophysics and Geodesy, 2020
A detailed knowledge of the thickness of crust and upper mantle structure is important for understanding a plate tectonics and geodynamics in the region. We use body wave for detecting details of the subsurface structure. The information in this research

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

open access: yes, 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.

3-D lithospheric structure and regional/residual Bouguer anomalies in the Arabia-Eurasia collision (Iran) [PDF]

open access: yes, 2013
The aim of this work is to propose a first-order estimate of the crustal and lithospheric mantle geometry of the Arabia-Eurasia collision zone and to separate the measured Bouguer anomaly into its regional and local components.
