Automatic estimation of regularization parameter by active constraint balancing method for 3D inversion of gravity data

M. Moghadasi; A. Nejati Kalateh; M. Rezaie

Volume 10, Issue 2 , April 2019, , Pages 357-364


  Gravity data inversion is one of the important steps in the interpretation of practical gravity data. The inversion result can be obtained by minimization of the Tikhonov objective function. The determination of an optimal regularization parameter is highly important in the gravity data inversion. In ...  Read More

3D gravity data-space inversion with sparseness and bound constraints

M. Rezaie; A. Moradzadeh; A. Nejati Kalate

Volume 8, Issue 2 , April 2017, , Pages 227-235


  One of the most remarkable basis of the gravity data inversion is the recognition of sharp boundaries between an ore body and its host rocks during the interpretation step. Therefore, in this work, it is attempted to develop an inversion approach to determine a 3D density distribution that produces a ...  Read More

Determining fractal parameter and depth of magnetic sources for ardabil geothermal area using aeromagnetic data by de-fractal approach

A. Khojamli; F. Doulati Ardejani; A. Moradzadeh; A. Nejati Kalateh; A. Roshandel Kahoo; S. Porkhial

Volume 8, Issue 1 , January 2017, , Pages 93-101


  The Ardabil geothermal area is located in the northwest of Iran, which hosts several hot springs. It is situated mostly around the Sabalan Mountain. The Sabalan geothermal area is now under investigation for the geothermal electric power generation. It is characterized by its high thermal gradient and ...  Read More

Underground contour (UGC) mapping using potential field, well log and comparing with seismic interpretation in Lavarestan area

M. Fakhrerad; A. Nejati Kalateh; S. Ghomi

Volume 6, Issue 1 , January 2015, , Pages 55-62


  Coastal Fars gravimetry project in Fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. The Lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. Depth structural model of this anticline made in previous ...  Read More

Estimation of 3D density distribution of chromites deposit using gravity data

Ali Nejati Kalateh; Amin Roshandel kahoo

Volume 4, Issue 2 , July 2013, , Pages 97-104


  We inverse the surface gravity data to recover subsurface 3D density distribution with two strategy. In the first strategy, we assumed wide density model bound for inverting gravity data and In the second strategy, the inversion procedure have been carried out by limited bound density. Wediscretize the ...  Read More
