Abstract: | The meaning of the term lineament, the modes of their recognition, and the lineament patterns dramatically varying in interpretations by different authors, are considered. It has been shown that obligatory identification of lineaments with faults and fracture zones is mostly implied rather than corroborated by evidence. The mapping of faults in platform regions based on lineaments requires distinct geological substantiation, otherwise lineament patterns remain devoid of sense. The regmatic system of supposedly tectonic dislocations cannot form on the surface of the rotating Earth, because the operating forces are too weak. Taking into account drift of continents and their rotation in the geological past, one hardly can speak of an ancient and inherited fault network. |
