Análise múltipla escala de sensores remotos óticos e de microondas aplicados ao estudo da Neotectônica na região de Manaus, Amazonas

Abstract

The tectonics models purpose for the Amazon region are adaptation of region model of others places in the brazil and world and needing the work filed. the most part of the study achieved is difficult by scarcity of good outcrops, therewithal maps thematics and cartoghaphy need be to update. Today is notorious which remote sensor aerotransport or orbit are tools very important in the obtaining of information and generation of new product, as to confirm in the tectonics movements at a determine region of the study. The setting geomorphologic of the Manaus region and adjoining is result of geologic processes initiated in period remote which yet act. Appreciation which remote sensing data from the platform orbit are an valuable information in the geological mapping, ore resource, engineering geology and projection of the environment. With previous images satellite, this work focused as generals aim of generation new product of remote sensing, which can be used in local an regional geological mapping, to establish cretirion methodology base on interpretation of product integration of Landsat-5 images satellite, Radasart-1, JERS-1, SRTM and IKONOS, showing the main advantages and limitation of the data of high, mean and low spatial resolution. To obtain of object proposal (to go) employee technic and method of photogeological interpretion conventional and aplication of modern technic processing digital of image, with detach into automatic lineament extraction. The results to obtein to demostrate which a utilisatio combined of technic of integrate the multi-source data, processing digital of image and photogeological interpretion are efficacius at constrution tectonic models local which assistant in compreension of models accept regionally. At region Manaus City go possible to characterize seven blocks tectonic. The study demonstract which at region of Manaus is powerful controller by structural alilinement and lineament. This feature have direction preferential N40-50W by river Tarumã-Mirim, Puraquequara, Preto da Eva, Urubu e Uatumã and N10-20E in the river Cuieiras e Tarumã-Açú, of which limited the tectonic block individualily. Subordinate is identificable an assemblage marked for alilinement for less of direction N40-60E, which control the tributary for less of river principal. Independety of tectonic models proposed whether in scale continent, regional or local, by the area of Manaus and adjoins, whather deduce of work is the utilizatio the new product and computtetion tools increase an efficacy of stractural analysis and contribute by construct of tectonic models greater consistent. Evidently which the methodology present hasn make use of isolatly, but naturally in association with the classic technic of interpretion visual and essentially with data survey of field.
