Fluvial dynamics of the Grande River and paleolandscape evolution in Northeastern Brazil Mateus Moriconi Prebianca, Vinícius Borges Moreira, Bruno Araújo Torres, André de Oliveira Souza, Everton Vinicius Valezio, Felipe Gomes Rubira, David Oldack Barcelos Ferreira Machado, Luca Lämmle, Archimedes Perez Filho Geomorphology, 2026 The Grande River stands out in the landscape of Northeast Brazil as one of the main tributaries of the São Francisco River - the largest river exclusively Brazilian, which supplies water to a significant portion of the country's northeast, a predominantly semi-arid region. Despite its notable natural, social, and economic importance, the Grande River lacks sufficient geomorphological and geochronological studies to provide a reliable landscape reconstruction over the past millennia. In this study, we propose a reconstruction of the fluvial dynamics of the middle Grande River over the last 35 ky through an integrated geomorphological analysis using satellite imagery and Digital Elevation Model (DEM) interpretations, field data collection, Optically Stimulated Luminescence (OSL) dating, and grain-size analyses of sediments. The results suggest the presence of a surface associated with a Pleistocene fluvial terrace (T1), a surface corresponding to a Holocene fluvial terrace (T2), the floodplain (FP) and paleochannel landforms, such as abandoned meanders, scars, and scroll bars. The morphogenesis of these features points to four phases: a predominantly erosive and energetic phase; base-level lowering and the abandonment of the T1 level; aggradation, lateral channel migration, and the development of the T2 surface; and the current phase, characterized by subtle channel incision and abandonment of the T2 terrace level. We conclude that the adjustments in the fluvial dynamics of the middle Grande River responded to cyclical allogenic factors followed by autogenic channel responses. While these transformations have likely occurred at the local level, their manifestations may have varied across the regional level. • A Pleistocene terrace (T1), a Holocene terrace (T2), and the floodplain were dated. • Paleochannel landforms, such as abandoned meanders, scars, and scroll bars, were mapped. • Base-level lowering/incision occurred in two phases during the last 35 ky. • Two phases of lateral migration through erosion or aggradation were also identified. • The coupling of allogenic/autogenic processes triggered these phases and paleoforms.
Genesis and Distribution of Low Fluvial Terraces Formed by Holocene Climate Pulses in Brazil Archimedes Perez Filho, Vinícius B. Moreira, Luca Lämmle, André O. Souza, Bruno A. Torres, Pedro I. C. Aderaldo, Éverton V. Valezio, David O. B. F. Machado, Mateus M. Prebianca, Alysson F. Mazoni, Carolina Zabini, Felipe G. Rubira Water Switzerland, 2022 Low fluvial terraces present azonal spatialization, encompassing several geomorphological compartments and climate zones in Brazil. Their genesis is directly related to river dynamics. When influenced by allogenic forces, such as Holocene climate pulses, it results in channel incision and posterior abandonment of the floodplain. Relatively plain landforms at different altimetric levels identified between the current floodplain and hillslope (low river terraces) are a result of these processes. Previous works using Optically Stimulated Luminescence (OSL) in low terraces of several rivers in Brazil have indicated morpho-chronologic similarities between depositional events, raising the hypothesis of feedbacks and fluvial adjustments relatively simultaneous to Holocene climate events. Considering these dynamics, this study employed OSL to obtain absolute dating information for 114 samples taken from distinct levels of the low river terraces of 30 rivers in Brazil, integrating the database of the IG-UNICAMP laboratory of Geomorphology and Environmental Analysis. Based on the data and statistical analysis (cluster and correlation analysis), this study aimed to identify relationships between different variables which might have controlled spatial homogenous and heterogeneous feedbacks during distinct paleoenvironmental contexts. The proposed methodology tested a fundamental hypothesis of the regional climatic geomorphology, and the results obtained may contribute to future discussions on the relationship between low river terraces and anthropic occupation.
Revisiting Alice Boer: Site formation processes and dating issues of a supposedly pre-Clovis site in Southeastern Brazil Astolfo G. Mello Araujo, James K. Feathers, Gelvam A. Hartmann, Francisco S. B. Ladeira, Éverton V. Valezio, Diego L. Nascimento, Olivia Ricci, Victor J. Oliveira Marum, Ricardo I. Ferreira da Trindade Geoarchaeology, 2022 Abstract The Alice Boer site, located in Southeastern Brazil, was considered to be one of the oldest sites in the Americas, and a strong candidate for being a pre‐Clovis site. Ages obtained by researchers during the 1970s and 1980s put the site inside a chronological range between 2 and 14 ka, eventually reaching as old as 30 ka or even 130 ka. Between 2010 and 2012, our research team revisited the site to improve the knowledge of Paleoindian occupation in Southeastern Brazil. Here, we present new data of stratigraphy and chronology (luminescence and radiocarbon dating), pedological and magnetic analysis performed at some of the sites. Results show that the site's oldest occupation took place ca. 8 ka, which provides new insight into human occupation in South America. In addition, we show some issues with radiocarbon contamination due to soil humin fraction mobility.
