Multiproxy reconstruction of Miocene-Holocene environmental changes in an estuarine succession of the Tinto River (SW Spain)
The sedimentary facies and foraminiferal assemblages of a core extracted from the middle estuary of the Tinto River (SW Spain) are studied to carry out a Miocene-Holocene palaeoenvironmental reconstruction of this area. During the Pleistocene, a strong erosion caused the dismantling of Neogene mater...

| Sumario: | The sedimentary facies and foraminiferal assemblages of a core extracted from the middle estuary of the Tinto River (SW Spain) are studied to carry out a Miocene-Holocene palaeoenvironmental reconstruction of this area. During the Pleistocene, a strong erosion caused the dismantling of Neogene materials previously deposited on a marine shelf during the Upper Miocene and Pliocene. Subsequently, this sector was occupied by tidal channels/mudflats, an alluvial plain with strong erosion of Neogene formations, a period of tidal inundation with tidal channels and mud flats during the MIS-1 transgression and finally the presence of high and supratidal marshes during the last 2 kyr. The upper part of core A is composed of an anthropogenic infill carried out in the late 20th and early 21st century |
