METHODOLOGY OF ANALYSIS THROUGH THE USE OF SATELLITE INFORMA-TION ON THE STRUCTURE AND MORPHOLOGY OF THE NORTHERN SECTOR OF THE ACHALA BATHOLITH AND ITS METAMORPHIC HOST ROCKS, SIERRAS PAMPEANAS OF CÓRDOBA. . Ser. correl. geol. [online]. 2017, vol.33, n.2, pp.1-10. ISSN 1666-9479.

The satellite technology development, with specific sofitware associated and the great diffusion of satellite images along with digital terrain models have allowed a great advance in the territorial land plan-ning for agronomic and urban uses, the development of natural hazards specific maps. Within the feld of geology has become an extremely useful work tool, which, knowing how to make use of it, allows the study of geological and tectonic units at regional and even global scale, which due to their dimensions have not been observed from a broader perspective. The digital processing tools, through algorithms, allow to discri-minate lithological units, fault slopes, structural lineaments, drainage network, and a long list of possibilities that allow the study of large geological units, as well as their relations with adjacent ones. Using this metho-dology on the northern sector of the Achala batholite and its metamorphic feld rocks, in the Sierra Grande of Córdoba (Sierras Pampeanas Orientales), valuable data on faulting, morphology and block tilting, due to the tectonic activity of the Retamito lineament and other parallel minor ones, have been provided. The use of digital terrain models has been useful to evaluate the traces of these lineaments throughout the studied area, verifying its northwest trend and its extension by more than 80 km, segmenting the batholith by its middle part, as well as to obtain the estimate of the topographical throw of more than 400 m between the two large blocks and their clockwise tilting.
