“…The deep basin is bounded along the margins by "uplifts" or horst-block highs that provide sediment to the basin. In terms of size, the Raoyang Sag is comparable to the Tucano Basin of Brazil, or the Lofoten margin of Norway (e.g., De Souza Rodrigues & Da Silva, 2018;Henstra et al, 2016). In the north, the Raoyang Sag is bound by the Baxian Sag, and to the south, the Raoyang Sag connects with a structural high, the Shenze Lower-Uplift (Cui, Li, & Li, 2005;Liu et al, 2002;Sun et al, 2004;Figure 1b).…”

The dynamics of sediment feeding into rift basins and the geomorphologic nature of source areas are critical elements in understanding the evolution of rifted basins. This study integrates seismic, well and geochronologic data on the western dipslope of the Raoyang Sag, a rift associated sub-basin to the larger Bohai Bay Basin of China to define the history of drainage development for the basin and to assess the sedimentologic response to drainage evolution events. In the Paleogene-age Lixian Slope, as indicated by paleo-drainage configuration, progradational seismic geometries, compositional maturity and zircon-tourmaline-rutile maturity index trends, three drainages; the paleo-Daqing River, paleo-Tang River and paleo-Dasha River drainages were feeding three closely spaced hanging wall deltaic depositional systems; Delta A fed from the northwest, Delta B fed from the west and Delta C fed from the southwest, respectively. From the late Eocene to early Oligocene, a decrease in sedimentflux into the hanging wall is documented and petrographic analysis is used to link these changes to stream-capture in the upstream catchment of the Daqing River. This change is coupled with morphologic changes in the geometries of Deltas A and C, both of which show decreasing deltaic areas, changes in lobe geometry and changes in distributary channel sizes. In addition, the progradational direction of Delta C changes from perpendicular-to-the-rift axis to prograding oblique-to-the-rift axis. It is apparent that the progradation and retrogradational changes in rift margin deltas do not happen in isolation, but such changes can affect growth and progradation direction in adjacent deltas. This work shows that the decrease in sediment-flux, caused by a drainage capture, will result in a decrease in distributary channel size and delta size and may result in upstream deltas taking advantage of such decreasing confinement to prograde more obliquely to the rift axis.

Highlights • Headward incision, stream capture or drainage diversion are drivers of sediment flux change to the Lixian slope, Raoyang Sag. • Temporal changes in channel morphometrics and energy can be coupled with petrographic observations to map a basin's sediment flux history. • Transverse deltas entering a rift interact, influencing each other's size and progradation directions. 118 | EAGE CHEN Et al. | 119 EAGE CHEN Et al. 120 | EAGE CHEN Et al.

“…Bandas de deformação podem ter variação significativa da geometria e orientação, então, a estrutura medida em afloramento pode ser composta por estruturas menores, anastomosadas com orientação diferente do volume da banda principal, como identificado por Rodrigues & Alves da Silva (2018). Por esse motivo, as amostras foram comparadas com a orientação das estruturas na scanline correspondente, porém sem resultados satisfatórios.…”
