In a previous article We are looking for ore gold on the island of Sumbawa, IndonesiaI talked about prospecting for gold in Indonesia, where, with a similar geological situation, gold veins often come to the surface, while in Siberia the veins are usually buried under sedimentary rocks. Of course, tens of meters of layers of different geological periods and composition greatly complicate the task of searching for ore minerals. In addition, there is the problem of the availability of geological data collected directly on the ground - the tasks of surveying the territory of warm Indonesia and frosty swampy Siberia are incomparable. And you should also remember about the specifics of Russia - detailed geological surveys of the times of the USSR are still classified (and after that they were not carried out, at least on a comparable scale), while paper maps and drilling data are in the archives.and the numbers of the wells on the maps and in the drilling reports are deliberately changed and the correspondence tables are kept by the Ministry of Defense ... as in the tale about the death of Kashchei. So in reality, these data are the same as they do not exist.

Due to the complexity of the problem, we need serious statistical methods such as multispectral analysis. Interestingly, we already have such an analyzer ... in our heads. This can be easily confirmed by the fact that we are able to distinguish the so-called "crimson ringing" of bells - this effect does not appear on the spectrum, but is clearly visible on the bispectrum. Most people are distinguished by bells with crimson ringing, it does not even require an ear for music. An experienced geologist engaged in visual interpretation of space images is able to manually identify elements on them that accompany various buried geological structures. As usual, we will use computational methods and build 3D geological models for automated analysis.
