Forward Modeling of Frequency-domain Helicopter-borne Electromagnetic Data using an Improved Finite Difference Method

Saeed Nazari; Alireza Arab Amiri; Abolghasem Kamkar Rouhani; Fereydoun Sharifi

Volume 13, Issue 4 , October 2022, , Pages 1067-1089


  In this work, we simulate the frequency-domain helicopter-borne electromagnetic (HEM) data over the two-dimensional (2D) and three-dimensional (3D) earth models. In order to achieve this aim, the vector Helmholtz equation is used to avoid the convergence problems in Maxwell’s equations, and the ...  Read More

Modeling of Induced Polarization and Resistivity Data for Prospecting and Exploration of Polymetallic Deposit in Kaboudan Area, East of Iran

F. Jamali; A.R. Arab Amiri; A. Kamkar Rouhani; A. Bahrami

Volume 12, Issue 3 , July 2021, , Pages 693-710


  In any geophysical exploration, the final goal is to achieve an accurate image of the relevant underground property. In order to achieve this, the geophysical operation using the electrical resistivity and induced polarization (IP) methods is conducted to explore the sub-surface sulfide mineralization. ...  Read More

An Exploration Model for A Gold Deposit in Kervian Area, Kurdistan Province, Iran, using a Combination of Geophysical Results with Geological Information and Other Exploratory Data

S. Najafi Ghoshebolagh; A. Kamkar Rouhani; A.R. Arab Amiri; H. Bizhani

Volume 12, Issue 2 , April 2021, , Pages 413-424


  As many gold deposits are associated with sulfide zones, and the direct exploration of gold deposits using the geophysical methods is very difficult due to its low amount in the sub-surface, the direct exploration of sulfide zones by the geophysical electrical resistivity and induced polarization (IP) ...  Read More

Using a combination of genetic algorithm and particle swarm optimization algorithm for GEMTIP modeling of spectral-induced polarization data

F. Sharifi; A.R. Arab Amiri; A. Kamkar Rouhani

Volume 10, Issue 2 , April 2019, , Pages 493-505


  The generalized effective-medium theory of induced polarization (GEMTIP) is a newly developed relaxation model that incorporates the petro-physical and structural characteristics of polarizable rocks in the grain/porous scale to model their complex resistivity/conductivity spectra. The inversion of the ...  Read More

A comprehensive benchmark between two filter-based multiple-point simulation algorithms

M. Bavand Savadkoohi; B. Tokhmechi; E. Gloaguen; A.R. Arab-Amiri

Volume 10, Issue 1 , January 2019, , Pages 139-149


  Computer graphics offer various gadgets to enhance the reconstruction of high-order statistics that are not correctly addressed by the two-point statistics approaches. Almost all the newly developed multiple-point geostatistics (MPS) algorithms, to some extent, adapt these techniques to increase the ...  Read More

Karstic water exploration using the Schlumberger VES and dipole–dipole resistivity profiling surveys in the Tepal area, west of Shahrood, Iran

Alireza Arab-Amiri; Fereydoun Sharifi; Abolghasem Kamkar-Rouhani

Volume 5, Issue 1 , January 2014, , Pages 1-12


  The need for clean groundwater resources to have sustainable development in a country is undoubted. Due to the importance and high quality of karstic waters in supplying water in Iran especially in Shahrood city, it is attempted in this research work to recognize and explore karstic waters in southwest ...  Read More
