The aims of this work are to characterize the paleoenvironmental evolution and sedimentary fluvial responses climate river flow changes upstream reaches Sado estuary since Mid-Late Holocene . By combining previous information, we also intent define limit fluvial-estuarine boundary maximum tidal influence estuarine area during last 4500 years. To accomplish these objectives a 10.5 m-long sedimen...

Le bassin rennais est majoritairement constitué de terrains briovériens, schisteux, fracturés et présentant des degrés d’altération variables. Briovérienpeut être recouvert par formations superficielles quelques intrusions magmatiques sont injectées dans les plus anciens. Les matériaux rencontrés ont une faible résistance mécanique qui classe en SIRT (Sols indurés Roches tendres). Pendant plusi...

ASBTRACT Some sectors of the west Portuguese coast are particularly endangered by erosion and flooding. Regional to local scale information, on coastline evolutionary trend, is valuable in that includes areas with relevant erosion. A continuous, high-resolution, dataset coastal evolution, from 1947 2015, between Figueira da Foz Nazaré, was achieved within Programme “Geological Coastal Hazard Ma...

Estuaries are important sediment facies in the fluvial-to-marine transition zone, strongly controlled by dynamic interactions of tides, waves, and fluvial flows, show various changes depositional processes distribution. Deep investigations on sand component estuaries have been conducted; however, understanding how mud supply affects estuaries’ sedimentary characteristics morphology is still vag...

Future sea-level rise poses an existential threat for many river deltas, yet quantifying the effect of changes on these coastal landforms remains a challenge. Sea-level have been slow compared to other processes during instrumental record, such that our knowledge comes primarily from models, experiments, and geologic record. Here we review current state science delta response change, including ...

The surface of the lowland deltaic plain around Taihu (Lake Tai), south Yangtze river mouth in eastern China, lies near sea level and until recent drainage development by human societies was mostly covered wetlands various types. It created regular overbank flooding, mainly from Yangtze, deposition mineral sediments over several millennia since regained its current altitude early mid-Holocene p...

Throughout the Holocene, two of most important factors involved in evolution tropical coastlines have been fluctuations sea level and regional climates. The geological record provides insightful realizations complex interaction between these factors, improving our understanding littoral zones. Here we present sedimentary a mangrove swamp located Punta Galeta, Caribbean coast Panama. Through con...

Abstract Cretaceous formation in the western Tabei Uplift is significant petroleum pay zone Tarim Basin, NW China. For complex relationship between tectonic movement and depositional environment, sequence stratigraphic filling model of whole has not been established yet. Using well logs seismic data this article, evolution process are interpreted involving paleo-uplift, sedimentary water-level....

Located on the northern coast of South China Sea, densely populated Pearl River Delta has experienced combined effects sea-level change, monsoon-driven discharge, and especially human activity, since late Holocene. However, how these factors have regulated regional environmental sedimentary evolution remains unclear. To better understand processes, we conducted a high-resolution rock magnetic i...
