Friday, 14 March 2008. The gravity method measures small spatial differences in the gravitational pull of the earth. If the gravity field over an air-filled void is measured, and the void is close enough to the ground surface, then a decrease in the gravitational pull across the void will be measured. This concept is illustrated in figure 1, which shows an underground void and the gravity profile over this void. Figure 2. The Lacoste and Rhomberg model EG gravity meter. (LaCoste and Romberg). The gravity...

Monday, 17 March 2008. Geoelectrical fields in a layered earth with arbitrary anisotropy. In many cases in geoelectrical exploration, the standard model of a layered isotropic half-space is a good approximation to geophysical reality. But sometimes it is useful to extend this model to uniform anisotropic layers. Manuscript received by the Editor September 8, 1997; revised manuscript received July 16, 1998.

Geophysics Journal: INTRODUCTION

Monday, 17 March 2008. Also for the layered transverse isotropic earth, one can use the equivalent isotropic models to replace the anisotropic resistivity (Niwas and Upadhyaya, 1974; Pal and Das Gupta,1984). The model of a dipping anisotropic half-space is proposed for the first time by Bhattacharya and Patra (1968). The most advanced model considered so far is that of Gurevich (1975).

Sunday, 7 December 2008. DATA ACQUISITION and PROCESSING. Data acquisition for magnetic surveys involves taking point readings at regular intervals on a survey grid. The spacing between grid lines and reading stations is dependant upon the application. Generally smaller targets require higher resolution surveys using denser survey grids. Modern caesium vapour magnetometers and gradiometers are more sophisticated allowing data to be collected either in continuous mode or as point readings. Finding buried ...

Sunday, 7 December 2008. Gravity and Magnetic Modeling. Gravity and Magnetic Modeling. Interpex offers two software tools that interpret magnetic and gravity profile data. The MAGIX family of software models data in 2, 2.5, and 2.75 dimensional earth models consisting of bodies and layers whose forward response matches the input data along a single profile line. The magnetic calculations take into account both induced magnetization and possible remanent magnetization. The remanent magnetization is en...
