Space between lines is 100 meters and space between electrodes is 50 meters. Induced polarization was measured by double dipole configuration as long as 2x1 kilometers. It used characteristic of polarization in medium when current was injected. One of geophysics method which suitable for metal mineral exploration is induced polarization method. It shaped as vein or dissemination of rock. Gold deposit was created by hydrothermal activity. Homepage: скачать бесплатно / free download Res2dinv圆4 Pro 4.8.Area TG was spotted as gold mineralization zone in Banyumas, Indonesia. The complex resistivity method (Kenma et al. Three different techniques for topographic modeling (Loke 2000) are available. Known boundaries where an abrupt change in the resistivity occurs can also be incorporated in the inversion model. Resistivity information from borehole and other sources can also be included to constrain the inversion process. chemical plumes), or with sharp boundaries (for eg. It can also be optimized to produce models with smooth boundaries (for eg. The smoothing filter can be adjusted to emphasize resistivity variations in the vertical, horizontal or diagonal directions. However, the inversion parameters can be modified by the user.
The program will automatically choose the optimum inversion parameters for a data set. It supports the Wenner, Schlumberger, pole-pole, pole-dipole, dipole-dipole, multiple gradient and non-conventional arrays. On a modern PC, the inversion of a single pseudosection is usually completed within seconds to minutes. It is completely automatic and the user does not even have to supply a starting model. The RES2DINV圆4 programs use the smoothness-constrained Gauss-Newton least-squares inversion technique (Sasaki 1992) to produce a 2D model of the subsurface from the apparent resistivity data. Two-dimensional (2D) electrical imaging surveys are now widely used to map areas of moderately complex geology where 1D resistivity sounding surveys are inadequate.
