Caracterização das feições geomorfológicas da paisagem da Serra do Tepequém (Norte de Roraima, Brasil)

The landscapes of the northern Roraima state represent a unique view in the Brazilian Amazon. In this scenario stand out tableland that can reach about 2.800 m altitudes known regionally by tepuis, like the example of Mount Roraima. These reliefs are made in the Roraima Supergroup sedimentary rocks, of Paleoproterozoic age. The Tepequém Mountain (object of study) is referred in the literature as a tabular structure with maximum altitudes of up to 1.100 meters. The study is based on the morphostructural features mapping through photointerpretatives techniques in remote sensing images in order to characterize the geomorphological features modeling the landscape of the mountain Tepequém. The applied procedures included mono and stereoscopic analysis for the recognition of natural elements (relief and drain), through the textural properties characterization. The textural elements were integrated using the techniques of digital image processing and have generated products such as morphostructural and relief maps, combined with the Numerical Model of Terrain (NMT) on the altitude and slope aspects. These products confirm the occurrence of various forms of relief at the top of the Tepequém Mountain, with a gap of up to 500 m, mischaracterizing the morphology of this type of tabular relief
