Abstract Large rivers are characterized by large water discharges, high suspended sediment fluxes and low slope, typically display multiple channels that separated complex bars. The most common channel style found in these is the alternating presence of single threads. Mid‐channel compound bars separate a main deeper from shallower secondary channels, leading to low‐order braiding moderate sinuosity. Despite importance this type river for global terrestrial transport interpretation ancient...
The tectonic evolution of southeastern South America from the Middle Ediacaran to Early Cambrian is marked by a series small fault‐bounded siliciclastic and volcaniclastic basins voluminous coeval granites traditionally associated with compressional or transpressional tectonics late stages Pan‐African‐Brasiliano orogeny. Most existing models consider these separately, distinct evolutionary histories according local geological settings. However, new recently published age constraints,...
The Aptian was characterized by dramatic tectonic, oceanographic, climatic and biotic changes its record is punctuated Oceanic Anoxic Events (OAEs). timing duration of these events are still contentious, particularly the age Barremian-Aptian boundary. This study presents a cyclostratigraphic evaluation high-resolution multiproxy dataset (δ13C, δ18O, MS ARM) from Poggio le Guaine core. identification Milankovitch-band imprints allowed us to construct 405-kyr astronomically-tuned model that...
Abstract Young rifts are shaped by combined tectonic and surface processes climate, yet few records exist to evaluate the interplay of these over an extended period early rift-basin development. Here, we present longest highest resolution record sediment flux paleoenvironmental changes when a young rift connects global oceans. New results from International Ocean Discovery Program (IODP) Expedition 381 in Corinth Rift show 10s–100s kyr cyclic variations basin paleoenvironment as eustatic sea...
Abstract The Ediacaran is one of the most important periods on Earth evolution, including first appearance soft‐bodied macrofossils, major climatic changes and a supposed rise in free oxygen. In southernmost Brazil, this period represented by Camaquã Supergroup, Bom Jardim Group Acampamento Velho Formation, both which record continental palaeoenvironmental more than 5000 m thick stratigraphic succession. Age constraints are given seven Ar‐Ar U‐Pb determinations volcanic rocks, bracket these...
Abstract The interpretation of fluvial styles from the rock record is based for a significant part on identification different types bars, characterized by geometric relationship between structures indicative palaeocurrent and surfaces interpreted as bar form accretion direction. These are boundaries flood‐related increment elements, which typically less abundant in outcrops than what would be desirable, particularly large river deposits each flood mobilizes volumes sediment, causing...
In Eastern South America, a series of fault-bounded sedimentary basins that crop out from Southern Uruguay to Southeastern Brazil were formed after the main collisional deformation Brasiliano Orogeny and record tectonic events affected region Middle Ediacaran onwards. We address problem discerning basin-forming tectonics later deformational through paleostress analysis more than 600 fault-slip data, mainly Camaquã Basin (Southern Brazil), sorted by stratigraphic level cross-cutting...

Abstract Rivers with little to no influence of vegetation and their implications for the architecture Early Paleozoic Precambrian fluvial deposits are an important topic investigation both clastic sedimentology Earth System evolution perspectives. Despite long‐held concept a dominant style wide, shallow sheet‐braided sandy channels, growing evidence great variability architectural elements in pre‐vegetation settings point predictable occurrence other styles, which possibly related areas...
The Camaqua Basin is an extensional post-orogenic and pre-cratonic rift system of Neoproterozoic-Early Cambrian age located in the Gaucho Shield, Rio Grande do Sul, southernmost Brazil. basin divided into a series small sub-basins which were filled with Group, thick (>9,000 m) unit composed three formations: (i) siliciclastic Marica Formation, (ii) volcano-sedimentary Crespos Formation (iii) Santa Barbara Formation. These units correspond to major stratigraphic sequences, are higher order...
ABSTRACT: One key factor for the advance in study of fluvial deposits is application geophysical methods, being Ground Penetrating Radar one special value. Although applied to active rivers, method not extensively tested on rock record, bearing interest hydrocarbon reservoir analogue models. The São Sebastião and Marizal formations were subject previous studies, which made possible comparison survey stratigraphic studies order identify best combination resolution, penetration antenna...
