“…Recently, the delta filling process and sedimentary patterns have been extensively studied worldwide in systems including the Nile Delta [5] and Niger Delta [6] in Africa, Rhone Delta [7,8] and Po River Delta [9] in Europe, Amazon Delta [10,11] in South America, Yellow River Delta [12][13][14] and Yangtze River Delta [15][16][17] in East Asia, Ganges-Brahmaputra Delta [18] in South Asia, and Red Delta [19,20], Mekong Delta [21,22] and Mahakam Delta [23,24] in Southeast Asia. In addition, a number of conceptual models have been developed to better understand the distribution of estuary sedimentary facies in studying deltas [25][26][27][28][29].…”

We analyzed the sedimentary characteristics and chronostratigraphy of the Pearl River Delta in South China, and discussed the Holocene stratigraphic characteristics and the filling process since the Holocene, based on 90 boreholes. Our results showed that the maximum transgressive surface of the Pearl River Delta was located in the soft marine silt horizons, whereas it was shown as an erosion surface in areas with tidal scour. From bottom to top, Holocene sedimentary sequences were fluvial facies, floodplain-estuary facies, and estuary-delta facies in the paleo-valley, while the paleo-interfluve sequences were described as littoral facies, estuary facies, and delta facies. Vertical accumulation sequences of Holocene sediments were shown primarily as positive tapering-shaped sequences with no typical foreset, topset, or other sedimentary sequences of the Gilbert Delta. The paleo-Pearl River estuary had different evolution models in the highstand systems tract (HST) compared with other large deltas worldwide, in that it is dominated by a unique and complex geomorphologic boundary, and that it is a multi-sourced delta compounded by the independent and parallel development of fluvial sedimentary bodies with different scales. A huge estuary was formed in the present Pearl River Delta area when the post-glacial transgression reached maximum at about 6 ka BP. The estuary was divided into two parts by obstruction of a series of islands, an upper part composed of the semi-enclosed inner paleo-bay connected to rivers and a lower part consisting of the outer paleo-bay connected to the ocean. Both of these areas were interlinked by only a few narrows, in which the fluvial sediments are accumulated primarily in the inner paleo-bay. During 6-2 ka BP, the sedimentation in various regions of the inner paleo-bay occurred simultaneously with independent development under the remodeling and transformation effect of complex boundaries on river and ocean dynamics. After 2 ka BP, the evolution of the delta is no longer a simple natural process, but rather a common remodeling process accomplished by nature and humans.Pearl River Delta, Holocene, stratigraphic framework, delta evolution Citation:Wei X, Wu C Y. Holocene delta evolution and sequence stratigraphy of the Pearl Deltas consist of large bodies of estuary sediments that are accumulated as a result of dramatic variations in sedimentary dynamic conditions when a river flows into a lake or ocean. The primary conditions dominating the development and evolution of a delta include climate and regional tectonics, as well as the dynamic equilibrium between rivers and lakes/oceans, relative sea-level fluctuations, sediment supply rate, and topography of the receiving basin. Due to variations in these factors and their interactions, the evolutionary process of a delta is complex. Early studies of the Mississippi Delta are now considered classic [1-3], therefore, this delta has long been taken as the model for deltas worldwide. However, Van Andel and Curray [4] found that

“…It consists of clay and silt with abundant organic matter but without marine bioclasts. The limit between Sd3p and Sd3ll at 7800 YBP is equivalent to the maximum flooding surface at the Rhone and Llobregat deltas defined by Boyer et al (2006) and Gámez et al (2009). Above this level, Sd3p and Sd3sup correspond to the top Tordera delta units.…”

Summary:The Tordera River Delta is made up of coarse sand bodies which were formed during the last sea level rise. Marine and land seismic profiles and wells show three depositional Holocene sequences corresponding to a) the transgressive base level, b) the progradant intermediate unit and c) the progradant unit which onlaps the Plio-Pleistocene sequence seawards and the granitic basement on the present delta plain and northern coast. The morphology of the sedimentary bodies, isobath maps and marine geophysical data enabled us to gain fresh insights into the evolution of the delta and its prodelta and into the various relict sand bodies on the inner shelf. The evolution of the coastline can be followed during the prograding process of the lower units from the successive coastal and internal lagoons. These coastal lagoons were conditioned by river changes and basement morphology. Once the sea level maximum was attained, the prograding units covered these morphologies, resulting in the present delta configuration.Keywords: Holocene delta; Tordera River; seismic and sedimentary sequences; Blanes Canyon; coarse-grained delta.Evolución del sistema deltaico del Río Tordera (NE de la Península Ibérica): secuencias sedimentarias y correlación mar adentro Resumen: El Delta del Río Tordera está formado por cuerpos de arena gruesa depositados durante el último ascenso del nivel del mar. Los perfiles sísmicos marinos y terrestres muestran tres secuencias deposicionales holocenas correspondientes a: a) el nivel de base transgresivo, b) la secuencia intermedia progradante y c) la secuencia que prograda hacia mar sobre el substrato plio-pleistoceno y el zócalo granítico en la llanura deltaica. La morfología de los cuerpos sedimentarios, la cartografía en isobatas y los datos geofísicos submarinos nos ofrecen nueva información sobre la evolución del delta, prodelta y de los diferentes cuerpos relictos de arena de la plataforma interna. La evolución de la línea de costa puede ser seguida a lo largo del proceso progradante de las secuencias anteriores a partir de la sucesión de lagunas costeras e internas. La presencia de estas lagunas estaba condicionada por los sucesivos cambios fluviales y la morfología del substrato. Una vez alcanzado el máximo eustático, las unidades superiores progradantes recubren estas morfologías dando lugar a la actual morfología deltaica.Palabras clave: delta holoceno; río Tordera; secuencias sísmicas y sedimentarias; Cañón de Blanes; delta de grano grueso.Citation/Como citar este artículo: Vila I., Serra J. 2015.

“…The following climate amelioration and the consequent disappearance of large portions of the glacial ice sheets triggered a dramatic eustatic sea-level rise during the Lateglacial-early Holocene period, leading to the drowning and subsequent infilling of the former incised valley systems around the globe (i.e. Boyer et al, 2005;Tanabe et al, 2006;Vis and Kasse, 2009). In the Arno coastal plain, the 35-40 m-thick valley fill is composed of transgressive estuarine and paludal deposits, emplaced during the post-glacial transgression between ca.…”
