Zaborovsky plots have been commonly used in Russia for many years to display apparent resistivity for Schlumberger soundings, TEM soundings and MagnetoTelluric soundings along profiles. The principle is simple; a vertical axis of apparent resistivity and a horizontal axis of profile distance shows the elevation and models, while an invisible horizontal axis is used to display electrode spacing, frequency, period or time. Each apparent resistivity curve is displaced along the profile according to the position where the measurement was taken.

Professor Aleksander Kaufman, of the Colorado School of Mines, formerly from Akademtown in Novosibirsk, Russia told me these were called "Apparent Resistivity" plots. I explained that there were many kinds of apparent resistivity plots and this particular format was unique. I asked him who was the first person to use such a plot. He said "Zaborovsky".

So now they are called Zaborovsky plots.
