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...

Geophysical survey methods bring information on the rock environment in real time, i.e. already during the geophysical survey. A geologist or a geotechnician provides such obtained information to a designer for the purpose of designing and implementation work at construction sites. Also, information on the effect of the rock environment or its properties (changing with time) on stabilization wo...

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...

[1] Rock physics attempts to relate the geophysical response of a rock to geologic properties of interest, such as porosity, lithology, and fluid content. The geophysical properties estimated by field-scale surveys, however, are impacted by additional factors, such as complex averaging of heterogeneity at the scale of the survey and artifacts introduced through data inversion, that are not addr...

A stochastic Bayesian approach for combining well logs and geophysical surveys for enhancing subsurface characterization is presented. The main challenge we face is in creating the bridge to link between ambiguously related geophysical surveys and well data. The second challenge is imposed by the disparity between the scale of the geophysical survey and the scale of the well logs. Our approach ...

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...
