This time, it is the first international interview, carried out with Professor Philip van Beynen, from the University of South Florida, in the United States. Professor Philip van Beynen was interviewed on the topic “Karst in Urban Areas”, and brings important data on the subject, with beautiful illustrations and with examples from all over the world. The interview took place on September 17, 2020, with the participation of Vanda de Claudino-Sales (Professor of the Academic Master in Geography at the State University of Vale do Acarau-UVA) and Saulo Roberto Oliveira Vital (Professor of the Department of Geography and the Post-Graduate Program in Geography at the Federal University of Paraiba - UFPB), and was transcribed by Diego Nunes Valadares, master's student on Geography at the Federal University of Rio Grande do Norte.</p> <p>Professor van Beynen was born in New Zealand, where he received his degree in Geography at the University of Auckland. He earned a master's degree from the same university, and a doctorate and post-doctorate from McMaster University, Canada. He has been a professor at the School of Geoscience at the University of South Florida since 2009, where he&nbsp;&nbsp; has been developing research related to different components of karst environments. The interview shows his great expertise on the subject, and is very much worth to be read and seen even for those who are not specialists in karst.</p> PHILIP VAN BEYNE, VANDA CLAUDINO-SALES, SAULO ROBERTO DE OLIVEIRA VITAL, DIEGO NUNES VALADARES Copyright (c) //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/130 Thu, 15 Jul 2021 17:10:45 -0300 GEOSITES AND GEOSYSTEMS IN QUATERNARY AND DYNAMIC LANDSCAPES – CASE STUDIES FROM A CRATONIC SETTING AND THEIR WIDER SIGNIFICANCE //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/137 <p>The rapidly expanding literature on the related subjects of geodiversity, geosites and their place in understanding and conserving our geoheritage has produced several proposed protocols for defining and valuing key sites and landscapes. Distinctions between geosites as well-defined features of our geological heritage and geodiversity sites as landscapes or geomorphosites have been proposed, while many subdivisions of the criteria for geosite recognition are also recognised. This paper uses two areas in central Africa to illustrate the realities of many landscapes, termed geosystems in this study. Largely Quaternary and present-day dynamic geosystems are considered as essential components of geodiversity and equally aspects of our geoheritage. To understand these geosystems requires detailed fieldwork including their relationships to ecology, rural land use and sensitivity to environmental change.</p> MICHAEL F.

Therefore, it starts from the theoretical-conceptual assumptions on the subject and continues highlighting the 20th century, when studies of the relationship between soil and relief were intensified, distinguishing the main approaches involving scales and study methods, subdivided into geospatial or cartographic and geodynamic or behavioral, both leading to the respective models and patterns. It is concluded that the 20th century left an important legacy to the subject.</span></p> SELMA SIMÕES DE CASTRO Copyright (c) //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/138 Thu, 15 Jul 2021 00:00:00 -0300 SPATIAL VARIATION IN THE RECENT GEOMORPHOLOGICAL EVOLUTION OF THE TURVO RIVER BASIN, IN THE MIDDLE VALLEY OF THE RIO PARAÍBA DO SUL: MORPHOLOGICAL AND CHRONOSTRATIGRAPHIC EVIDENCES/VARIAÇÃO ESPACIAL NA EVOLUÇÃO GEOMORFOLÓGICA RECENTE DA BACIA DO RIO TURVO //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/136 <p>Morphological and chronostratigraphic evidence indicates that the region of the middle valley of the Paraíba do Sul River (MVRPS) went through two cycles of morphodynamic instability: the first between 10,000 and 8,000 years ago, and the second, which started about 250 years ago (cycle of coffee). This evolutionary dynamic was widely proven for the Bananal River basin, right slope of the MVRPS. Therefore, this study aimed to evaluate the repercussions of these two cycles in the Rio Turvo basin, left slope of the MVRPS. Surveys of fluvial deposits were made in several sub-basins, through mapping and thickness the volumetry of these deposits was obtained. 15 analyzes were performed by C<sup>14</sup> dating in 9 stratigraphic profiles. Geochronological studies (AMS C<sup>14</sup>) on the river terraces of the Turvo and Pedras rivers show that they were formed in the same erosive-depositional cycle, between 8000-10000 years ago, identified for the Bananal River basin. However, erosion rates were higher in the Bananal River basin (Piracema River sub-basin) (38,500 m<sup>3</sup>/year), followed by the Pedras River sub-basin (2,240 m<sup>3</sup>/year) and other Turvo River sub-basins (320 m<sup>3</sup>/year). On the other hand, comparing the sedimentation rates of the coffee period, similar rates were observed between the basins of the Turvo and Bananal rivers (96,640 m<sup>3</sup>/year and 97,160 m<sup>3</sup>/year, respectively). The results point to a spatially non-uniform geomorphological evolution model, with the Rio Pedras sub-basin having a greater erosive-depositional magnitude, while in the rest of the Turvo river basin there is less sediment stock in the river valleys and the preservation of chemical denudation features. in the interfluves.</p> RAFAEL ALBUQUERQUE XAVIER, ANA LUIZA COELHO NETTO Copyright (c) //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/136 Thu, 15 Jul 2021 16:07:22 -0300 CONSIDERATIONS ABOUT THE GEOMORPHOLOGICAL MACROUNITIES OF THE STATE OF MINAS GERAIS – BRAZIL/CONSIDERAÇÕES SOBRE AS MACROUNIDADES GEOMORFOLÓGICAS DO ESTADO DE MINAS GERAIS – BRASIL //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/109 <p>The state of Mina de Gerais is marked by the diversity of geomorphological landscapes, influenced by elements of a geological order (structure and lithology), and climatic (denudational processes). The present work presents the state's macrounities relief areas, as well as demonstrating the importance of different events in the evolution of relief in the northern sector of the state. The methodology was based on bibliographic review and field work, with analysis of geological data and processing of radar images in a GIS environment. As a result, you can view different compartments, such as saws, plateaus, plateaus and erosion surfaces in the territory of Minas Gerais. As a highlight, in the North of Minas Gerais, a mesoregion that aggregates important relief units, sculpted at the interface between the São Francisco Craton and the Araçuaí Orogen, it is possible to visualize the importance of processes that emphasize shapes with more denudational or morphostructural characteristics.</p> LUIS RICARDO FERNANDES DA COSTA Copyright (c) //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/109 Fri, 23 Apr 2021 00:00:00 -0300 ASPECTS OF GEODIVERSITY IN THE WEST OF ACRE STATE - BRAZIL //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/108 <p>Geodiversity is associated with aspects of geoconservation, natural geological and hydrogeomorphological heritage in each morphoclimatic domain in Brazil. In the Amazon domain, such aspects have been forged in an environment of sedimentary origin since the Cretaceous, identified in the Rio Branco, Juruá-Mirim, Moa and Jaquirana mountains, composed predominantly of sandstones and siltstones. The Serra do Divisor National Park (PNSD) is located in the state of Acre, on the border with Peru and the Andes mountain range. The region has a natural heritage and a geological-geomorphological structure, where waterfalls, caves, valleys and high hills are found, endogenous to the site. The general objective of this article is to present elements of the Geodiversity of the Serra do Divisor National Park (PNSD) focused on the category of geotourism aiming at dissemination at regional, national and international levels.</p> FRANK OLIVEIRA ARCOS, ELISANDRA MOREIRA DE LIRA, HILZA DOMINGOS SILVA DOS SANTOS ARCOS Copyright (c) //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/108 Fri, 23 Apr 2021 00:00:00 -0300 GEOMORPHOLOGICAL PROPERTIES OF THE ROCKS AND THEIR REPERCUSSIONS IN THE RELIEF OF THE NORTH SECTOR IN BRAZILIAN NORTHEAST REGION/PROPRIEDADES GEOMORFOLÓGICAS DAS ROCHAS E SUAS REPERCUSSÕES NO RELEVO DO NORDESTE SETENTRIONAL DO BRASIL //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/135 <p>The geomorphological properties of rocks are endogenous factors in the formation of reliefs and influence several aspects, with emphasis on surface runoff, mechanical breakdown and chemical weathering. The northern sector of the Northeast region of Brazil has landscapes developed on lithologies from the Borborema and Parnaíba provinces, whose mosaic of lithological units leaves distinct marks along the regional morphology. The present work aims to present the main lithological reflexes in the geoforms in this area and it was elaborated from bibliographical reviews, use of geoprocessing techniques and fieldwork. The results were divided according to the main regional lithological categories (metamorphic rocks, magmatic rocks, sedimentary rocks and sedimentary deposits) and their respective morphostructural reflections.</p> FREDERICO DE HOLANDA BASTOS, ABNER MONTEIRO NUNES CORDEIRO Copyright (c) //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/135 Thu, 15 Jul 2021 16:34:00 -0300 WHAT DO WE KNOW ABOUT THE INSELBERGUES OF QUIXADÁ AND QUIXERAMOBIM, NORTHEAST OF BRAZIL?/O QUE SABEMOS SOBRE OS INSELBERGUES DE QUIXADÁ E QUIXERAMOBIM, NORDESTE DO BRASIL? //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/110 <p>The inselbergs are exceptional reliefs and have scientific, environmental, educational, tourist and cultural relevance. Its genesis is associated with differential weathering in more resistant rocks, due to mineralogical, petrological or fracturing conditions. In the Northeast of Brazil, the field for insurgents in the counties of Quixadá and Quixeramobim is one of the most representative on Earth. They are features sculpted in exhumed granitic rocks that have resulted in different forms of meso and microscale. In view of this, these territories were the subject of a geopark proposal. In this article, we analyze the state of the art about knowledge, its origins, evolution and classification. Therefore, we quantify publications on the area under study and synthesize the main theories and discussions, in order to assist strategies for the sustainable use of local geoheritage.</p> JOÃO LUÍS SAMPAIO OLÍMPIO, FELIPE ANTONIO DANTAS MONTEIRO, LUIS CARLOS BASTOS FREITAS, LUIZA TEIXEIRA DE ALMEIDA, ALEXANDRE PINHEIRO DE ALCÂNTARA, CAROLINE VITOR LOUREIRO, MARCOS LEITE NASCIMENTO, RUBSON PINHEIRO MAIA Copyright (c) //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/110 Fri, 23 Apr 2021 00:00:00 -0300 GEOMORPHOLOGICAL MAPPING OF THE CHORÓ RIVER HYDROGRAPHIC BASIN - CEARÁ, BRAZIL/MAPEAMENTO GEOMORFOLÓGICO DA BACIA HIDROGRÁFICA DO RIO CHORÓ- CEARÁ, BRASIL //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/134 <p><strong>ABSTRACT</strong></p> <p>The present work presents the geomorphological mapping of the Choró River Hydrographic Basin, following the criteria established by Ross (1992), based on morphostructural and morpho-sculptural conditions.

After the interpretation of Landsat 8 satellite images, thematic maps were elaborated with the support of the Sudene/DSG SB.24-V-B-1 (Santa Quitéria) and SB.24-V-A-III (IPU) sheets on the 1:100,000 scale. The methodology used was systemic analysis through bibliographic survey, cartographic and field work. Being possible the identification of 4 Geoenvironmental Units: the sertaneja depression, the river plain of the Acaraú River, the residual massifs and the Sedimentary Plateau of Ibiapaba. It begins with geological characterization and ends with the integration of geomorphological components, allowing to establish relationships between the forms and deposits inherited from previous geological periods, as well as the evolutionary trends present.</p> ERNANE CORTEZ LIMA , CAMILA DA SILVA CARNEIRO Copyright (c) //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/122 Thu, 15 Jul 2021 16:55:24 -0300 TIME, SPACE, AND CAUSALITY IN GEOMORPHOLOGY //williammorrisdavis.uvanet.br/index.php/revistageomorfologia/article/view/111 <p>The distinction between cause and effect in the development of landforms is a function of time and space (area) because the factors that determine the character of landforms can be either dependent or independent variables as the limits of time and space change. During moderately long periods of time, for example, river channel morphology is dependent on the geologic and climatic environment, but during a shorter span of time, channel morphology is an independent variable influencing the hydraulics of the channel.</p> <p>During a long period of time a drainage system or its components can be considered as an open system which is progressively losing potential energy and mass (erosion cycle), but over shorter spans of time self-regulation is important, and components of the system may be graded or in dynamic equilibrium. During an even shorter time span a steady state may ex1st. Therefore, depending on the temporal and spacial dimensions of the system under consideration, landforms can be considered as either a stage in a cycle of erosion or as a system in dynamic equilibrium.</p> S.
