“…Benthonic forms can be used for a range of palaeoenvironmental studies, although in most published studies bathymetry is always the most important aspect (Montenat et al 1976;Wright 1978;Troelstra et al 1980;Van der Zwaan and Den Hartog Jager 1983;Murray 1991;Fortuin et al 1995). In order to calculate the changing palaeobathymetry of the Sorbas Basin during deposition of the Abad Member, the main parameters used in other established palaeobathymetric studies were identi®ed.…”

“…The most important foraminiferal palaeobathymetric studies on the Abad Member are: Vo Èlk (1967), Montenat et al (1976), Cita et al (1980) and Carbonnel (1990), who indicated deposition at upper bathyal depths (> 180 m); and Fortuin et al (1995) who estimated deposition at upper±middle bathyal depths (180±1300 m). However, these studies were based upon just a few samples taken from scattered localities, and as such do not give an adequate representation of the depositional history of the Abad Member across the basin.…”

“…However, several small-scale studies of the benthonic foraminifera from the Abad Member have been made (Vo Èlk 1967;Iaccarino et al 1975;Montenat et al 1976;Civis et al 1979;Dronkert et al 1979;Porta et al 1979;Troelstra et al 1980). These have concentrated upon palaeobathymetric reconstructions, the results of which support very generalized trends, and give vague and unsatisfactory bathymetries for the Abad Member marls.…”

“…The benthonic assemblages reveal a detailed history of the palaeoenvironmental conditions that prevailed during the deposition of the Abad Member. Early works concentrated on palaeobathymetry (Vo Èlk 1967;Montenat et al 1976), and estimated a depth of around 200 m for deposition of the marls. More recent studies (Van de Poel 1992;Fortuin et al 1995) have argued for deeper, lower epibathyal (500±1300 m) conditions, in which the marls were deposited.…”

ABSTRACT. The Late Tortonian-Early Messinian Abad Member in the Sorbas Basin, south-east Spain contains abundant foraminifera. Planktonic foraminifera have been used to reconstruct the environmental conditions that developed within the basin. Benthonic foraminifera reveal a detailed picture of the palaeoenvironment. After an initial deepening episode, from upper epibathyal (c. 200 m) depths to lower epibathyal (c. 1000 m) depths, the basin progressively shallowed to shelf depths (c. 100 m); this palaeobathymetric reconstruction thus describes an initial rapid transgressive episode, a highstand and a regressive phase; the basin water mass became progressively warmer, and yet there was no signi®cant increase in salinity or oxygen level in the water mass. The lack of any microfossil evidence to support an increase in the salinity levels towards the top of the Abad Member indicates a rapid environmental switch from normal marine conditions during the deposition of the Abad Member to hypersaline conditions during deposition of the overlying Yesares Member and precipitation of great thicknesses of gypsum. This research illustrates the necessity for high resolution sampling, approximate to the standard interval (10 feet: c. 3 metres) used in industrial boreholes, for Mediterranean Late Miocene stratigraphies, and indicates that all previous palaeoenvironmental studies on the Sorbas Basin have had inadequate sampling regimes which do not represent the evolving environmental conditions of the Abad Member.

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
