Conteúdo: | In Brazil, studies of zoning in wine have contributed to the development of geographical indications. As for the geographical identity, the geology of the criteria has been a subject of research. The region of the Serra Gaúcha, located in northeastem Rio Grande do Sul, Brazil, has a geodiversity that induce the formation of soils and terrain, comprising natural and cultural factors that imply different responses of agronomic vine. These features value the production of wines with unique qualities, which can define different terroirs. The region is at the limit of the geomorphologic units Serra Geral and Planalto dos Campos Gerais, generated from the rocks of the Serra Geral Formation. ln the Pinto Bandeira geographical indication for fine wines occurs in the most of area, the Caxias Facies of Serra Geral Formation, which is composed of intermediate to acid rocks (rhyodacite), originated 131 million years ago during a vo1canic fissural event of continental extension. The rocks are grayish mesocratic and show fine granular to microphaneritic texture. The area cultivated with vineyards in the Pinto Bandeira geographical indication is located on higher altitudes and lower slopes terrains, on the tops of the plateaus, occupied by rocks of Caxias Facies. Soils formed on parent material of the Caxias Facies are a set of argisoils, cambisoils and nitosoils. To integrate the information was prepared a base map in O1S for zoning studies and also to spatializing different descriptors of natural factors. To construct the geological sketch, photo-interpretation techniques were employed high-resolution aerial photos associated with field work. The digital image processing was used to construct the digital elevation model from high resolution orbital data and its derivatives such as altimetry, slope and exposure, as well as the geological structures and land forms.
