“…The FRO of the G. conomiozea group, with an astronomical age of 7.24 Ma , has been widely used as a biostratigraphic indicator for the Tortonian/Messinian boundary. The event has also been recognised in the Northeast Atlantic (Feinberg and Lorenz, 1970;Bossio, 1976;Cita and Ryan, 1978;Sierro, 1985;Sierro et al, 1993;Hodell et al, 1989;Benson et al, 1991). Unlike the Mediterranean, where these groups have never been found coexisting (with the exception of the Potamida section on Crete; Zachariasse, 1979b), the G. menardii group is clearly replaced by the G. miotumida group after a short period of coexistence in the Atlantic (Sierro, 1985;Sierro et al, 1993).…”

“…This event is immediately preceeded by the LO of the group of G. menardii 5 and is a well known event usually cited in the Mediterranean as the FRO of the G. conomiozea group (Zachariasse, 1975(Zachariasse, , 1979aD'Onofrio et al, 1975;Iaccarino et al, 1975;Bossio et al, 1976;Gonzalez Donoso and Serrano, 1977;Cita and Ryan, 1978;Glac Ëon et al, 1990;Sierro et al, 1993Sierro et al, , 1997Krijgsman et al, 1994Krijgsman et al, , 1995Krijgsman et al, , 1997.

“…The Abad marls have always been considered to be of early Messinian age and belong to the Globorotalia mediterranea and Globigerina multiloba subzones of D 'Onofrio et al (1975) Civis et al, 1979;Gonzales Donoso and Serrano, 1977;Van de Poel, 1991;Sierro et al, 1993). The base of the G. mediterranea subzone was recognized near the base of the Abad marls (Gonzales Donoso and Serrano, 1977;Sierro et al, 1993Sierro et al, , 1996.…”

“…The base of the G. mediterranea subzone was recognized near the base of the Abad marls (Gonzales Donoso and Serrano, 1977;Sierro et al, 1993Sierro et al, , 1996. The limit between the G. mediterranea and G. multiloba subzones was approximately correlated with the coiling change in Neogloboquadrina acostaensis that occurred in the middle part of the Upper Abad (Civis et al, 1979;Gonzales Donoso and Serrano, 1977;Geerlings, 1977;Van de Poel, 1991;Sierro et al, 1993;Gautier, et al, 1994). This latter event has been widely recognised throughout the Mediterranean below the Lower Evaporites, or the laterally equivalent Calcare di Base (Zachariasse, 1975;Colalongo, et al, 1979;Sprovieri, et al, 1996a,b).…”

“…The distribution and coiling pattern of the unkeeled globorotaliids throughout the Messinian has proved to be very useful for biostratigraphic correlations both inside and outside the Mediterranean (Sierro et al, 1993;Krijgsman 1996;Krijgsman et al, 1995Krijgsman et al, , 1997. The group of Globorotalia scitula (including G. scitula s.s., G. suterae, G. nicolae, G. ventriosa) is relatively abundant during the lower part of the Messinian and reveals frequent shifts in coiling direction, from sinistral to dextral and vice versa.…”

A high-resolution integrated stratigraphy is presented for the Abad marls of the Sorbas and Nijar basins in SE Spain (preevaporitic Messinian of the Western Mediterranean). Detailed cyclostratigraphic and biostratigraphic analyses of partially overlapping subsections were needed to overcome stratigraphic problems in particular encountered at the complex transition from the Lower to the Upper Abad. The resulting Abad composite section contains a continuous stratigraphic record from the Tortonian/Messinian boundary up to the transition to the Messinian evaporites of the Yesares Member. All together, 18 calcareous plankton events were recognized which were shown to be synchronous throughout the Mediterranean by means of detailed (bed-to-bed) cyclostratigraphic correlations. The magnetostratigraphy allowed the identi®cation of the four magnetic reversals of chron C3An in the Upper Abad. Details in the sedimentary cycle patterns allowed the Abad composite to be astronomically calibrated. This calibration to the 658N summer insolation curve of solution La90 (1,1) yielded astronomical ages for all sedimentary cycles, calcareous plankton bioevents, ash layers and paleomagnetic reversals. Up to now, the Abad composite is the only astronomically well-calibrated section that provided a reliable cyclostratigraphy, magnetostratigraphy and calcareous plankton biostratigraphy. As such it will serve as a reference section both for the pre-evaporite Messinian in the Mediterranean as well as for the Messinian interval in the Astronomical Polarity Time Scale. q

Tectonic inversion of an asymmetric graben: Insights from a combined field and gravity survey in the Sorbas basin

et al. 2014

The formation of sedimentary basins in the Alboran domain is associated with the exhumation of metamorphic core complexes over a circa 15 Ma period through a transition from regional late-orogenic extension to compression. An integrated study coupling field analysis and gravity data acquisition was performed in the Sorbas basin in the southeastern Betic Cordillera. Detailed field observations revealed for the first time that extensional tectonics occurred before shortening in this basin. Two extensional events were recorded with NW-SE to N-S and NE-SW kinematics, respectively; the first of which being likely responsible for the basin initiation. Tectonic inversion of the basin then occurred around 8 Ma in an overall approximately N-S shortening context. Two-dimensional gravity sections reveal that the basin acted as an active depocenter as the basin floor locally exceeding 2 km depth is characterized by a marked asymmetric architecture. Based on this integrated study, we explore a new evolutionary scenario which can be used as a basis for interpretations of the Neogene tectonic history of the southeastern Betics.

Sr isotope records from marginal marine basins track the mixing between seawater and local continental runoff, potentially recording the effects of sea level, tectonic, and climate forcing in marine fossils and sediments. Sr/ 86 Sr analyses from the astronomically tuned Lower Evaporites in the central Apennines (Italy) allow us to explore the effect of glacio-eustatic sea level and precipitation changes on 87 Sr/ 86 Sr. Most variation in our data can be explained by changes in sea level, with greatest negative excursions from global seawater values occurring during relative sea level lowstands, which generally coincided with arid conditions in the Mediterranean realm. We suggest that this greater sensitivity to lowered sea level compared with higher runoff could relate to the inverse relationship between Sr concentration and river discharge. Variations in the residence time of groundwater within the karst terrain of the circum-Mediterranean region during arid and wet phases may help to explain the single (robust) occurrence of a negative excursion during a sea level highstand, but this explanation remains speculative without more detailed paleoclimatic data for the region.
