Thank you mate,
If I have data of soil resistivity on ohm meter, can I estimate the litologiy / laminations of various ground soil and what of the parameters.
This is trial version software, can you give me the full software or patch? Where I must be download? in rapidshare?
You can estimate the litology of various ground soil by using only true resistivity data. There are three kinds of resistivity in electrical imaging (tomography) such as equipment resistivity (R), apparent resistivity (rho_a), and true resistivity (rho). If you just have rho_a data you need to convert it first to rho data by using inversion software to solve rho_a to rho inverse problem.
Before interpreting rho data you need to know about geologic condition, water table, climate, material resistivity characteristic, and organic matter contents. Geologic condition important in determining what kind of mineral that formed soil formation. Water table elevation is important to know because water can make a drastic change in soil resistivity especially when the surface soil is rich in acidic ion from organic matter decomposition. Material resistivity is used for converting resistivity data to lithology so resistivity data need to be correlated with nearest borehole.
I’m so sorry actually Geophysical Department of Moskva State University just share the shareware version, so I don’t have the full version because it’s so expensive. I think that for just on educational purpose, the shareware version is enough.
