“…The high geodiversity pattern in the southeastern part of the ADB corresponds to the northeastern part of the São Francisco Craton [ 96 ]. The coastal areas generally contain very low to low values of geodiversity, with the exception of the Guiana coastal region and south of the city of São Luís, where the São Luis Craton is located [ 49 ] ( figure 3 ). Lastly, there is a distinct area of very low geodiversity south of the Central Brazilian Shield, which coincides with the head of the Xingu river catchment and the Tocantins-Araguaia river system.…”

“…The cratonic regions represent the formation, amalgamation and break-up of former supercontinents [ 102 ], with numerous examples of belts, complexes and suites that are a testament to the cratons' long and geologically dynamic history. Good examples of this early history are the Trincheira Complex, which is associated with the supercontinent Columbia [ 55 ], the Nova Brasilândia-Aguapeí Belt, which is related to the amalgamation of Rodinia [ 57 ], the Gurupi [ 49 ] and Araguia Belt [ 56 ], which are both related to the amalgamation of Gondwana, and the Anarí Formation, a remnant of the magmatic activity preceding the break-up of Pangea [ 54 ]. Other areas, such as the Colider Suite [ 58 ] and Mucajai Anorthosite-Monzonite-Granite Complex [ 59 ], are suitable for palaeomagnetic studies, allowing the reconstruction of the orientation of palaeocontinents.…”

The Amazon is the largest drainage basin on Earth and contains a wide variety of abiotic landscape features. In spite of this, the geodiversity in this basin has not yet been objectively evaluated. We address this knowledge gap by combining a meta-analysis of an existing global geodiversity map and its components with a systematic literature review, to identify the key characteristics of geodiversity in the Amazon drainage basin (ADB). We also evaluate how these global geodiversity component maps, that are based on the geology, geomorphology, soils and hydrology, could be refined to better reflect geodiversity in the basin. Our review shows that geology—through lithological diversity and geological structures—and hydrology—through hydrological processes that influence geomorphology and soil diversity—are the main determinants of geodiversity. Based on these features, the ADB can be subdivided into three principal regions: (i) the Andean orogenic belt and western Amazon, (ii) the cratons and eastern Amazon, and (iii) the Solimões-Amazon river system. Additional methods to map geomorphological and hydrological diversity have been identified. Future research should focus on investigating the relationship between the geodiversity components and assess their relationship with biodiversity. Such knowledge can enhance conservation plans for the ADB. This article is part of the Theo Murphy meeting issue ‘Geodiversity for science and society’.

“…-The Gurupi belt (11) crops out along the São Luis Craton (SCL; Figure 1) and is limited to the west by the Neoproterozoic Araguay belt. Ages determined with the Rb/Sr and K/Ar methods [34] were complemented by recent U/Pb ages on zircon [35,36] and indicate that the São Luis Craton comprises rocks with ages ranging from ca. 2200 to 1920 Ma, supporting a connection with the Ivory-Coast Shield.…”

Linking the Neoproterozoic to Early Paleozoic Belts Bordering the West African and Amazonian Cratons

Correlations between the Neoproterozoic belts surrounding the West African Craton and northern Brazilian cratons have long been a subject of interest and controversies. Due to the splitting of African and South American continents by the Atlantic oceanic domains, no direct links are preserved, requiring relying on various geological or geophysical characteristics to propose such correlations. In addition to the opening of the Atlantic oceanic domains, another difficulty arises from the covering of northern Brazilian belts by upper Paleozoic and Mesozoic basins, making these correlations speculative. Recently, four orogens have been evidenced in the Neoproterozoic belts of the western margin of the West Africa Craton, while the belts on the eastern side underwent only one orogeny. Similarities with the Pan-African I (900-650 Ma) and with the Pan-African II (650-480 Ma) orogenic events have been evidence in the western Brazilian belts (Araguay and Paraguay). The two first orogens on the western margin (Pan-African I and Pan-African II) can thus be extended to the western Brazilian belts and can be considered as parts of a single geodynamic system running from the Mauritania to the Paraguay including the “Gurupi rift” as an aulacogen connected to the NNW-SSE Panafrican I and II oceanic domains. Consequently, the eastern Brazilian belt should rather be linked the Eastern Trans-Saharan belts.
