Caracterização geológica e geomorfológica do remanescente florestal da UTFPR, Campus Dois Vizinhos

Abstract

The Forest Remnant of the Federal University of Technology – Paraná, Dois Vizinhos campus, represents a conservation and scientific study area, established in 1993. Its creation aims to preserve the site against deforestation caused by agricultural activities. This work carries out the geological and geomorphological characterization of the outcropping rocks in this region, where the understanding of the fissural volcanism of the Serra Geral Formation is deepened to make it possible to comprehend the processes that were involved in its origin. The areas of focus for the study were the Erveira river, the basalt wall, and the canyon. To conduct the research, methods such as in situ analysis, basalt sample collection, X-ray diffraction tools, and geodetic surveying were used. The work emphasizes how weathering and erosion processes, influenced by biotic and abiotic factors, have modified the structure and composition of the rocks in the remnant over time. In conjunction with the mineralogical research, important data were obtained, indicating the dominant presence of plagioclases such as Sodium Anorthite, Albite, and Labradorite, along with the pyroxene Augite and the oxide Ilmenite, near the sample collected close to the Erveira river. The research included high-precision geodetic measurements using a state-of-the-art GNSS receiver, ensuring that the altimetry and geographic coordinates of the selected points are highly reliable. The information obtained serves as the foundation for the creation of a chapter in an eBook, aimed at disseminating knowledge about the remnant’s geodiversity to the general public.
