Voçorocas na Serra do Tepequém, Norte da Amazônia Brasileira: morfometria e solos

Abstract

This study examines Barata gully, Tepequém mountain, Amazonia, characterising the erosive feature and analysing the physical properties of the soil. Using a DSM, orthophotos, and field data, we analysed geomorphological features, like area of regressive erosion, banks of the channel, slopes, and pipes. Analyses revealed a silty-sandy soil, rich in quartz, with muscovite flakes and kaolinite matrix. Erosion follows NE-SW-oriented faults and fractures, and diamond mining increased erosion.
