Late Miocene–early Pliocene planktonic foraminifer event-stratigraphy of the Bajo Segura basin: A complete record of the western Mediterranean

Early Pliocene continental vertebrate Fauna at Puerto de la Cadena (SE Spain) and its bearing on the marine-continental correlation of the Late Neogene of Eastern Betics

“…All the macro and micropaleontological data indicate that sedimentation of the Cigarrón Unit began under normal salinity marine conditions in a shallow water depositional environment, and a subsequent transgressive event can be recognized at the top of La Virgen Fm. This transgressive event is recorded in the same way in numerous places in the Bajo Segura Basin, coinciding with the beginning of the Pliocene (Corbí and Soria, 2016). This implies that the erosive surface documented at the base of the Cigarrón Unit corresponds to the end-Messinian discontinuity (Soria et al, 2005 and…”

The Origin of Sand and Its Colour on the South-Eastern Coast of Spain: Implications for Erosion Management

“…The studied coast has very diverse habitats: dunes in the south [30], high cliffs of the Betic Cordillera in the north coast of Alicante [31], as well as beaches located on the Nueva Tabarca Island [23]. From a geological standpoint, this coastline is divided into three different domains: the southern sector mainly belongs to the Bajo Segura basin [32,33], the northern one pertains to the Prebetic zone of the External Zones of the Betic Range [34], while the Island of Tabarca is related to the Internal Zones of the Betic Range [35]. The different geological contexts in which the beaches are included establish broadly three different source areas of sediments, which constitute an intrinsic factor that determines natural sand composition and hence the native beach colour.…”

The Messinian stromatolites of the Sierra del Colmenar (Western Mediterranean): facies characterization and sedimentological interpretation

“…2 ). This basin presents one of the most complete Miocene and Pliocene (P) records of the Mediterranean margin, showing an exceptional record of the different sedimentological and palaeoenvironmental phases associated with the Messinian Salinity Crisis ( Soria et al, 2008a , 2008b , 2014 ; Corbí, 2010 , 2017 ; Caracuel et al, 2011 ; García-García et al, 2011 ; Soria et al, 2014 ; Corbí & Soria, 2016 ; Corbí et al, 2016 , 2018 ). In the northern sector, where our study is focused, the Messinian and Pliocene units present facies associations typical of shallow marine and continental environments; while in the southern sectors, the Messinian and P units record facies associations corresponding to deeper marine environments ( Viseras, Soria & Fernandez, 2004 ).…”

“… (A) Geological map of the Bajo Segura basin, indicating the position of the studied section. (B) Synthetic stratigraphic architecture of the northern sector of the Bajo Segura basin, with the location of the study section (for a detailed description Soria et al, 2008a , 2008b ; Corbí, 2010 ; Corbí et al, 2016 ; Corbí & Soria, 2016 ). Different colors mark the age of the different units: light blue (Basement, External Zones), orange (Tortonian), yellow (Messinian), green (Pliocene) and gray (quaternary).…”

“…According to the most recent studies ( Soria et al, 2008a , 2008b ; Corbí et al, 2016 ; Corbí & Soria, 2016 ), the marine sedimentary record of the Bajo Segura basin can be divided into five major allostratigraphic units (synthems), termed Tortonian I (TI), Tortonian II (TII), Tortonian-Messinian I (T-MI), MII, and P. These synthems are bounded by basin-wide unconformities: the intra-Tortonian (i-T), end-Tortonian (e-T), intra-Messinian (i-M), and e-M discontinuities ( Figs. 2 and 3 ).…”
