Designing of Exploration Algorithm to Generate Optimum Mineral Potential Models and Management of Exploration Operation: A Special Emphasis on Preliminary Exploration of Gold Deposits

Mahyar Yousefi; R. Gholami; A. Kamkarr-Ruhani; A. Moradzade

Volume 21, Issue 81 , December 2011, , Pages 135-142


  In the systematic exploration plan for prospecting the mineral deposit, we can design an exploration algorithm using the modeling of known mineral occurrences. Such an algorithm is a key to recognize the area where is high probability of mineralization, reduce the risk of exploration and increases the ...  Read More

Definition and Comparison Improved Mundry’s Integral with Mundry’s Integral on HEM Data Inverse Modeling

A.R. Arab-Amiri; A. Moradzadeh; D. Rajabi; B. Siemon; N. Fathianpour

Volume 19, Issue 75 , January 2010, , Pages 115-118


  It is about 30 years that Helicopter electromagnetic (HEM) surveys are being used for rapid mineral and ground water exploration, environmental investigations and also geological mapping in extensive areas. Despite this, one of the most important problems in using obtained data from the surveys is accurate ...  Read More

Investigation of HEM Forward Modeling Accuracy on Inverse Modeling

A.R. Arab-Amiri; A. Moradzadeh; D. Rajabi; N. Fathianpour; B. Siemon

Volume 20, Issue 77 , January 2010, , Pages 137-140


  Today Helicopter-borne electromagnetic (HEM) data survey play important role for high resolution and fast 3D mapping of resistivity structures within the vast area. The standard method of interpretation of these data is to inverse them frequently. As surveying system is not fixed during the survey, hence ...  Read More

Estimation of Horizontal Location and Depth of Gravity Anomalies using Normalized Full Gradient (NFG)

H. Aghajani; A. Moradzadeh; H. Zeng

Volume 19, Issue 76 , January 2010, , Pages 169-176


  Estimation of depth and horizontal location of anomalous bodies plays an important role for selecting exploration wells location. There are many methods for depth estimating, and most of them use high-pass filters. The Normalized Full Gradient (NFG) method is one of these methods that use Fourier series ...  Read More

Interpretation of Magnetic Data from an Iron Deposit in Northeast of Semnan

A. Moradzadeh; F. Doulati Ardejani; B. Tayebi

Volume 18, Issue 71 , January 2009, , Pages 63-68


   There are a few iron deposits in the north and northeastern part of Semnan city that none of them has a systematic exploration background. Ojat_Abad deposit is one of them located in 63 km of north-east of Semnan at the southern side of Semnan - Damghan main road. A magnetic survey including 1200 ...  Read More

An Investigation on the Possibility of Two-Dimensional Joint Inversion of TE and TM Modes Data in Magnetotelluric (MT) Survey using Artificial Neural Network

A. Moradzadeh; F. Tahmasbi; M. Fateh

Volume 16, Issue 64 , March 2007, , Pages 88-101


         The magnetotelluric (MT) method is a natural source electromagnetic geophysical technique, which is used mainly in petroleum, mineral and geothermal exploration. As in this method, the quantity of the measured data is bulky and have a complex structure, their modeling, ...  Read More
