Cross-strata palaeocurrent analysis using virtual outcrops

Freitas, Bernardo T.; Silva, Leonardo H. G.; Almeida, Renato P.; Galeazzi, Cristiano P.; Figueiredo, Heitor G.; Tamura, Larissa N.; Janikian, Liliane

Made available in DSpace on 2021-06-25T10:57:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Although virtual outcrops or digital outcrop model applications in geological studies are becoming increasingly common, virtually no attention has been given to acquisition of palaeocurrent data from cross-strata. Palaeocurrent indicators are abundant in the sedimentary record, mainly as cross-strata, a...

Large barchanoid dunes in the Amazon River and the rock record : implications f...

The interpretation of large river deposits from the rock record is hampered by the scarcity of direct observations of active large river systems. That is particularly true for deep-channel environments, where tens of meters deep flows dominate. These conditions are extremely different from what is found in smaller systems, from which current facies models were derived. MBES and shallow seismic surveys in a sele...

Ground penetrating radar investigation of depositional architecture : the São S...

Tamura, Larissa Natsumi; Almeida, Renato Paes de; Taioli, Fabio; Marconato, André; Janikian, Liliane

Um fator-chave para o avanço no estudo de depósitos fluviais é a aplicação de métodos geofísicos, e o Radar de Penetração no Solo é um método de especial valor. Embora amplamente aplicado em ambientes de rios ativos, em ambientes fluviais consolidados esse tipo de estudo é mais escasso, em contrapartida há uma grande importância em mais estudos de modelos análogos de hidrocarboneto. Por essa motivação, o presen...
