Delineation of oxide and sulfide zones in mineral deposits, especially in gold deposits, is one of the most essential steps in an exploration project that has been traditionally carried out using the drilling results. Since in most mineral exploration projects there is a limited drilling dataset, application of geophysical data can reduce the error in delineation of the sulfide and oxide zones....

This work presents the application of a geostatistical-based modeling approach for building up electrical properties acquired from a geophysical electrical tomography survey deployed for the purpose of porphyry Cu exploration at the Takht-e-Gonbad deposit, in the central domain of Iran. Electrical data were inverted in 2D along several profiles across the main favorable zones of Cu-bearing mine...

Shallow depth geophysical data from archaeological sites contain various levels and types of noise that hinters the valuable information of the subsurface architectural relics. Wavelet transform techniques were tested as a method for decomposition of the original geophysical data in order to eliminate the noise levels inherent to the geophysical measurements. In addition to the above, unsupervi...

Characterization of fractured-bedrock aquifers is one of the most difficult problems in hydrogeology. Successful characterization of aquifers at the site scale requires the effective integration of the three basic tools at our disposal: 1) surface geophysical soundings provide full non-destructive coverage of the aquifer volume but are generally ambiguous in interpretation and fail to identify ...

This work aims at figuring out the spatial relationships between the geophysical and geological models in a case study pertaining to copper-sulfide mineralization through an integrated 3D analysis of favorable target. The Ghalandar Skarn-Porphyry Cu Deposit, which is located in NW Iran, is selected for this research work. Three geophysical surveys of direct current electrical resistivity and in...

The ability to produce three-dimensional physical property models of the subsurface from surface geophysical data, coupled with an increasing need to explore for minerals in concealed terranes, results in geophysical inversions providing more significant information to the exploration team. We examine the role that geophysical inversion can play in an integrated mineral exploration program, and...

in march 2004, a fluxgate gradiometer survey was conducted over tepe ghabristan, covering approximately 6ha of ground. it identified further areas of the iron age cemetery with possible grave pits (areas b and c). in addition, an irrigation channel was discovered which could be contemporary to these iron age graves (area d). the anomalies in area e can be interpreted as buried structural remain...

Agrogeology is a relatively new applied, problem-solving, interdisciplinary earth and agricultural science that aims at improving agricultural production using agromineral resources. There are two aspects of agrogeology: 1. The influence of parent material on soil development and soil fertility, and 2. The beneficial application of rocks and minerals to enhance soil fertility and crop productiv...
