Deciphering of structural units of Russian Federation territory, using space image compared from NOAA AVHRR images of EROS Data Center within spectral bands at 580-680 and 720-1100 nm, allows us to reveal continental, deep-rooted lineaments extending from 500 km to 5400 km in latitudinal, longitudinal and diagonal directions over Russian territory and neighboring countries. These lineaments or zones of lineaments, 50 to 250 km in width, extend in a significantly heterogeneous upper crust. They can penetrate the Earth down to deep lithosphere layers, inheriting a position of old fault-lineament systems, being related to Precambrian to Paleocene tectonic processes. Some of these structural discontinuities are poorly expressed in surface geology, but can be detected by remote sensed methods, as well as by the magnetic and gravity anomalies. These lineaments, when projected over surface geology, extend across boundaries of crustal blocks, modern stress provinces or across allochthonous and folded terranes. The distribution of lineaments in RF territory is uneven, with maximum concentration of complex combinations of diversely oriented lineaments observed between 80° E and 140° E (region of East Siberian plate and its folded frame). Latitudinal lineaments similar to those known in USA and Australia are typical for Russia also.
