Finite Difference Migration Imaging of Magnetotellurics
we put forward a new migration imaging technique of Magnetotellurics (MT) data based on improved finite difference method, which increased the accuracy of difference equation and imaging resolution greatly. We also discussed the determination of background resistivity and reimaging. The processing results of theoretical model and case study indicated that this method was a more practical and ef...
متن کاملAdvances in aspects of the application of magnetotellurics for mineral exploration
Figure 1. Power spectra of two time series recorded at different times in the Sudbury area (Canada). Evident is the increase in the amplitude for the nighttime hours (bold lines) compared to the daytime hours (light lines). The continuous lines denote real part and the dashed linesimaginary parts of the spectra. Advances in aspects of the application of magnetotellurics for mineral exploration ...
متن کاملMT+, Integrating Magnetotellurics to Determine Earth Structure, Physical State, and Processes
As one of the few deep-earth imaging techniques, magnetotellurics provides information on both the structure and physical state of the crust and upper mantle. Magnetotellurics is sensitive to electrical conductivity, which varies within the earth by many orders of magnitude and is modified by a range of earth processes. As with all geophysical techniques, magnetotellurics has a non-unique inver...
متن کاملBoat-towed radio-magnetotellurics — A new technique and case study from the city of Stockholm
We have developed a new data acquisition system and technique to measure the radio magnetotelluric (RMT) signals from distant radio transmitters with the objective of mapping and modeling electric resistivity structures below a river or lake. The acquisition system is towed by a boat; therefore, we call the technique boat-towed RMT. The data acquisition is fast with a production rate of approxi...
متن کاملIbn Sīnā’s Practical Philosophy
This article is a brief review of Ibn Sīnā’s practical philosophy. It begins with a discussion of the Platonic, Aristotelian, and Neo-Platonic influences on Ibn Sīnā’s practical philosophy, as well as the influence of Fārābī and of Islamic religious teachings. The creative synthesis invented by Ibn Sīnā requires a particular view of the relation between religion and philosophy in such a manner ...
