• Abstract

  Are the Precambrian erg depositional systems similar to present ergs in inland deserts? Is the lack vegetation in the terrestrial Earth the main controlling factor for formation of aeolian deposits in pre-Silurian age? Or did other factors control the Precambrian sedimentation in aeolian-dominated systems? These are the main questions and the leitmotiv that drive this project. The abundan…

• Abstract

  Palaeosols are relatively common in continental and paralic sedimentary successions. Despite that, they are ignored or described as massive sediments and interpreted as chaotic debris flows or diagenetic changes. This superficiality considering palaeosols cannot be justified studying continental and paralic sedimentary successions because they constitute very important proxies of palaeoen…

• Abstract

  To characterize the factors controlling transport and deposition from shelf to deepwater basins, is extremely interesting for the human society. In fact, these factors determine the geometry and depositional architecture of the beds that currently constitute one of the main goal of the world petroleum industry. Two aspects of this scientific argument are not too clear: i) the relevance of…

• Abstract

  Fluvial facies models are vastly based on models of tributary rivers under humid climates. However, state-of-art in fluvial sedimentology demonstrates that the majority of the stratigraphic record is composed of distributive fluvial systems (DFS). As a consequence, this approach, focused a priori over a restrict fluvial end-member, establishes a deficient ground to comprehend ancient dist…

• Abstract

  Global distribution of Precambrian ERG systems is highly fragmented, making it difficult to understand the depositional systems developed during this period. The distinction between pre- and post-vegetation deposits, as well as the main factors that influenced the development and preservation of these strata, are still not well understood. Verify the wind influence of as a depositional fa…

• Abstract

  Recent studies regarding arid to semiarid fluvial systems have been conducted, on the last few years, through detailed field studies and laboratorial analysis. Fluvial deposits from the Bauru Group, located in the Triângulo Mineiro region (Serra da Galga Member), build up layers of medium-coarse immature sand, showing trough cross stratifications, suggesting permanent channelized flow, al…
