“…The Upper member is Middle Plioceneaged and corresponds to Madre de Dios Formation itself (Carlotto et al 2008). Conglomerates of the base of the lower member (Ipururo Formation) often contain the Huayquerian fauna of mammal fossils (SALMA -South American Land Mammals Age), indicating Late Miocene age between 9 and 6.5 Ma for the associated fauna and sediments of Solimões Formation, very well detailed by Latrubesse et al (2007Latrubesse et al ( , 2010. In the area of Eirunepé, eastward from the Envira Arch, the Solimões Formation with Huayquerian fauna was described in further detail by Gross et al (2011).…”

“…Following the drainage reorganization at the beginning of Late Miocene, the Late Miocene-Early Pliocene-aged Solimões Formation (Cruz, Zone B, 1984, Silva 2004, Latrubesse et al 2007, 2010 and others) represents the Amazon River sedimentation towards the Atlantic Ocean, when the sea level rose again, since it exhibits Andean palynomorphs (Nogueira et al 2013, Motta 2008) and minerals (Mapes 2009), in the east of the Purus Arch, as well.…”

The development of the transcontinental Amazon River System involved geological events in the Andes Chain; Vaupés, Purus and Gurupá arches; sedimentary basins of the region and sea level changes. The origin and age of this river have been discussed for decades, and many ideas have been proposed, including those pertaining to it having originated in the Holocene, Pleistocene, Pliocene, Late Miocene, or even earlier times. Under this context, the geology of the sedimentary basins of northern Brazil has been analyzed from the Mesozoic time on, and some clarifications are placed on its stratigraphy. Vaupés Arch, in Colombia, was uplifted together with the Andean Mountains in the Middle Miocene time. In the Cenozoic Era, the Purus Arch has not blocked this drainage system westward to marine basins of Western South America or eastward to the Atlantic Ocean. Also the Gurupá Arch remained high up to the end of Middle Miocene, directing this drainage system westward. With the late subsidence and breaching of the Gurupá Arch and a major fall in sea level, at the beginning of the Late Miocene, the Amazon River quickly opened its pathway to the west, from the Marajó Basin, through deep headward erosion, capturing a vast drainage network from cratonic and Andean areas, which had previously been diverted towards the Caribbean Sea. During this time, the large siliciclastic influx to the Amazon Mouth (Foz do Amazonas) Basin and its fan increased, due to erosion of large tracts of South America, linking the Amazon drainage network to that of the Marajó Basin. This extensive exposure originated the Late Miocene (Tortonian) unconformity, which marks the onset of the transcontinental Amazon River flowing into the Atlantic Ocean.

“…Latrubesse and coworkers (Latrubesse et al, 1997(Latrubesse et al, , 2007(Latrubesse et al, , 2010 conclude that trans-Amazon drainage occurred sometime between 6.5 and 5 Ma, soon after deposition of the Solimões Formation ceased in the Solimões basin of the western Brazilian Amazon. Leguizamon Vega et al (2006) used sedimentological evidence to conclude that the Purus Arch was an effective barrier to eastward, transcontinental Amazon drainage until at least the late Miocene.…”

The development of a genomics-derived discipline within geology is timely, as a result of major advances in acquiring and processing geologically relevant genetic data. This paper articulates the emerging field of "geogenomics," which involves the use of large-scale genetic data to constrain geological hypotheses. The paper introduces geogenomics and discusses how hypotheses can be addressed through collaboration between geologists and evolutionary biologists. As an example, geogenomic methods are applied to evaluate competing hypotheses regarding the timing of the Andean uplift, the closure of the Isthmus of Panama, the onset of trans-Amazon drainage, and Quaternary climate variation in the Neotropics.

A multidisciplinary approach is used to analyze the Cenozoic uplift history of South America. Residual depth anomalies of oceanic crust abutting this continent help to determine the pattern of present‐day dynamic topography. Admittance analysis and crustal thickness measurements indicate that the elastic thickness of the Borborema and Altiplano regions is ≤10 km with evidence for sub‐plate support at longer wavelengths. A drainage inventory of 1827 river profiles is assembled and used to investigate landscape development. Linear inverse modeling enables river profiles to be fitted as a function of the spatial and temporal history of regional uplift. Erosional parameters are calibrated using observations from the Borborema Plateau and tested against continent‐wide stratigraphic and thermochronologic constraints. Our results predict that two phases of regional uplift of the Altiplano plateau occurred in Neogene times. Regional uplift of the southern Patagonian Andes also appears to have occurred in Early Miocene times. The consistency between observed and predicted histories for the Borborema, Altiplano, and Patagonian plateaux implies that drainage networks record coherent signals that are amenable to simple modeling strategies. Finally, the predicted pattern of incision across the Amazon catchment constrains solid sedimentary flux at the Foz do Amazonas. Observed and calculated flux estimates match, suggesting that erosion and deposition were triggered by regional Andean uplift during Miocene times.
