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

https://doi.org/10.22044/jme.2022.11837.2173

Abstract
  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

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

https://doi.org/10.22044/jme.2021.10353.1985

Abstract
  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

https://doi.org/10.22044/jme.2021.10403.1989

Abstract
  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

https://doi.org/10.22044/jme.2019.7902.1655

Abstract
  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

Detection and determination of groundwater contamination plume using time-lapse electrical resistivity tomography (ERT) method

S. Moghaddam; S. Dezhpasand; A. Kamkar Rohani; S. Parnow; M. Ebrahimi

Volume 8, Issue 1 , January 2017, , Pages 103-110

https://doi.org/10.22044/jme.2015.523

Abstract
  Protection of water resources from contamination and detection of the contaminants and their treatments are among the essential issues in the management of water resources. In this work, the time-lapse electrical resistivity tomography (ERT) surveys were conducted along 7 longitudinal lines in the downstream ...  Read More

Dimensionality analysis of subsurface structures in magnetotellurics using different methods (a case study: oil field in Southwest of Iran)

M. Filbandi Kashkouli; A. Kamkar Rouhani; Ali Moradzadeh; H. Assi

Volume 7, Issue 1 , January 2016, , Pages 119-126

https://doi.org/10.22044/jme.2016.468

Abstract
  Magnetotelluric (MT) method is an electromagnetic technique that uses the earth natural field to map the electrical resistivity changes in subsurface structures. Because of the high penetration depth of the electromagnetic fields in this method (tens of meters to tens of kilometers), the MT data is used ...  Read More

Prediction of mineral deposit model and identification of mineralization trend in depth using frequency domain of surface geochemical data in Dalli Cu-Au porphyry deposit

H. Shahi; R. Ghavami Riabi; A. Kamkar Ruhani; H. Asadi Haroni

Volume 6, Issue 2 , July 2015, , Pages 225-236

https://doi.org/10.22044/jme.2015.458

Abstract
  In this research work, the frequency domain (FD) of surface geochemical data was analyzed to decompose the complex geochemical patterns related to different depths of the mineral deposit. In order to predict the variation in mineralization in the depth and identify the deep geochemical anomalies and ...  Read More

A GIS-based weights-of-evidence model for mineral potential mapping of hydrothermal gold deposits in Torbat-e-Heydarieh area

Hossein Shahi; Abulghasem Kamkar Rouhani

Volume 5, Issue 2 , July 2014, , Pages 79-89

https://doi.org/10.22044/jme.2014.324

Abstract
  The method of weights of evidence is one of the most important data driven methods for mineral potential mapping in GIS. In this method, considering the characteristics of known mineralized locations, we can prospect new mineralized areas. In this research work, the method of weights of evidence has ...  Read More
