1 Revue de Paléobiologie, Genève (juin 2010) 29 (1) : ISSN Biostratigraphic remarks on the Caltavuturo Formation (Eocene-Oligocene) cropping out at Portella Colla (Madonie Mts., Sicily) Andrea BENEDETTI 1 Abstract An outcrop of the Caltavuturo Formation (Eocene-Oligocene) in the Madonie Mts. (Northern Sicily) has been micropaleontologically investigated. Two stratigraphic sections were sampled and studied in rock thin sections. The formation consists of marly clays and several 2-30 cm thick breccia layers, rich in larger foraminifers, and is affected by prominent silicification and bioturbation. The clayey layers are dominated by deep-water agglutinated foraminifera (DWAF) in isolated forms, with rare epibathyal and bathyal hyaline taxa, which disappears at the top of the succession. The collected samples are barren of planktonic foraminifera and calcareous nannoplankton. Selected larger benthic foraminifers species in the displaced layers register a vertical variation and were analysed to have a biostratigraphical control according to shallow benthic zones (SBZ). Heterostegina reticulata italiaca, Borelis vonderschmitti, Halkyardia minima, Dyscocyclina dispansa dispansa, Orbitoclypeus varians and Nummulites ex. gr. incrassatus mark the upper Eocene assemblages. Nummulites vascus dominates the Early Rupelian assemblages in association with N. fichteli, Halkyardia maxima, Operculina complanata and Heterostegina sp., whereas the FO of Nephrolepidina praemarginata marks the Late Rupelian. Imbrication of resedimented larger foraminiferal tests indicates a N-S paleodirection of the flows. Keywords Larger foraminifera, systematics, biostratigraphy, SBZ, Eocene, Oligocene, Sicily. I. INTRODUCTION Micropaleontological investigations on the Caltavuturo Formation, belonging to Imerese domain and cropping out at Portella Colla (Madonie Mts., Northern Sicily), provide new evidence on Late Eocene-Oligocene foraminiferal assemblages (Benedetti & Pignatti, 2008). The autochtonous assemblages are dominated by deep water agglutinated foraminifera (DWAF) studied in isolated forms, whereas allochtonous and coeval larger foraminifera assemblages occur in resedimented breccias layers. The investigated sections belong to the Caltavuturo Formation (Schmidt di Friedberg et al., 1960), cropping out 20 km south of Cefalù, between Monte dei Cervi and Monte Mùfara ( N E) (Fig. 1). At Portella Colla the Caltavuturo Fm. does not exceed 30 m thick (Grasso et al., 1978) and dip 25 S-E, it is conformably overlain by the Portella Colla Clay (Wezel, 1966), considered the lower member of the Numidian Flysch. Micropaleontological data on the Caltavuturo Fm. are scarce and fragmentary (Wezel, 1966). The aim of this work is to present the results of biostratigraphic studies on thin sections and dry residue samples of displaced larger foraminifera assemblages of two investigated stratigraphic sections cropping out in the above mentioned places ; this formation in fact was never sufficiently investigated in the past and it is one of the richest in Eocene to Oligocene larger foraminifera in the north-western Sicily containing some undescribed forms. II. THE PORTELLA COLLA OUTCROP AND THE INVESTIGATED SECTIONS Two sections were sampled to investigate the Portella Colla outcrop (Figs. 1, 2). The first one was identified by the abbreviation PC and is about 24 m thick including the top of the Crisanti Fm. The second section, abbreviated MM, was sampled along a gully erosion and measures about 10 m. At the base of the investigated succession a detritic limestone crops out, assigned to the Crisanti Formation (Schmidt di Friedberg et al., 1960). The contact between the Crisanti Fm. and the Caltavuturo Fm., not directly visible in the analysed sections, is described as transgressive in the literature (Schmidt di Friedberg et al., 1960 ; Ogniben, 1960, 1963 ; Grasso et al., 1978). 1 Department of Earth Sciences, Sapienza University, Piazzale A.

3 Biostratigraphic remarks on the Caltavuturo Formation (Eocene-Oligocene) 199 The Caltavuturo Fm. consists of marly clays and several 2-30 cm thick breccia layers rich in larger foraminifers and is affected by prominent silicification and bioturbation. Clay colour changes upsection : it is wine red at the bottom and becomes gray from the middle towards the upper part of the outcropping sections. The clay layers contain poor foraminiferal assemblages studied in isolated forms, essentially composed by DWAF, hyaline benthic or planktonic foraminifera are being rare and badly preserved (Benedetti & Pignatti, 2008). Some samples are completely barren of hyaline taxa, rare epibathyal and bathyal hyaline taxa such as Cibicidoides occurs in the uppermost Eocene and lower Rupelian samples and disappears in upper Rupelian sediments (Benedetti & Pignatti, 2008). This suggests a deposition of the clay layers close or below the CCD. III. BIOSTRATIGRAPHICAL DATA The top of the Crisanti Fm. can be referred to the Aptian according to the presence of assemblages essentially composed by Palorbitolina sp. and Trocholina aff. alpina (Leupold) sensu Arnaud-Vanneau, Boisseau & Darsac, As previously described, the clayey layers of the Caltavuturo Fm. are devoid of planktonic foraminifera with the exception of some badly preserved specimens of Globoquadrina ex. gr. tapuriensis-tripartita isolated from the gray clays. The DWAF assemblages and the rare benthic hyaline taxa are composed by cosmopolitan taxa with a prolonged stratigraphical range. For example Cibicidoides grimsdalei (Nuttall, 1930) and C. havanensis (Cushman & Bermudez, 1937) occurring in the red clay of the PC section and in the early gray clay of both sections, range from early Eocene to Miocene. In the resedimented layers several displaced larger foraminiferal taxa occur : the assemblages are allochthonous and reworking seems to be extremely limited, except for rare Cretaceous forms such as orbitoidids. Therefore it was attempted to use larger foraminifera for dating the succession using the standard biozones of Serra-Kiel et al. (1998) for the Eocene and Cahuzac & Poignant (1997) for the Oligocene. In the lowermost part of the Caltavuturo Fm. the displaced larger foraminifera dominated layers are absent, and the first occurrence of these taxa is in the sample PC2 for the section PC (Fig. 3). Heterostegina reticulata italica Herb, 1978, Borelis vonderschmitti (Schweighauser, 1951), Discocyclina dispansa dispansa (Sowerby, 1840), Orbitoclypeus varians (Kaufmann, 1867) and Halkyardia minima (Liebus, 1911) indicate SBZ 19 (Serra-Kiel et al., 1998) ; no markers strictly referred to SBZ 20 (Late Priabonian) were found. In the section MM (Fig. 4) this stratigraphic interval is absent, no Late Eocene markers was found. The first occurrence of Nummulites vascus Joly & Leymerie, 1848 marks the Early Rupelian in both the investigated sections. This species was found associated with other nummulitids such as N. fichteli Michelotti, 1841, Operculina complanata (Defrance, 1822), Heterostegina sp. (maybe a new species), borelids such as Borelis pygmaea Hanzawa, 1930 and B. inflata Adams, 1965 and others foraminifers : Victoriella conoidea (Rutten, 1914), Halkyardia maxima Cimerman, 1969 and Praearchaias sp. These assemblages characterize SBZ 21 of Cahuzac & Poignant (1997). The FO of Nephrolepidina marks the upper Rupelian (SBZ 22A). Specimens referred to this orbitoidiform taxon was even found displaced in some clay layer. Six populations were isolated and megalosphaeric embryo were biometrically investigated (Benedetti & Pignatti, in prep.) and, according to the parameters and factors proposed by De Mulder (1975), all the sampled population can be referred to N. praemarginata (Douvillé, 1908) and so the whole top of the Caltavuturo Fm. can be referred to the Late Rupelian. These assemblages are characterized by the dominance of N. praemarginata with subordinate presence of Eulepidina formosoides Douvillé, 1924 and Halkyardia maxima. Specimens of Sphaerogypsina globulus (Reuss, 1848) and Planorbulina sp. are common from the Late Eocene to the top of the Caltavuturo Fm. IV. ON THE FLOWS ORIGIN In the past, several hypothesis were developed about the direction and the origin of the flows which originated the Caltavuturo Fm. and the Numidian Flysch in general (Broquet, 1968a, b, 1972 ; Broquet & Duée, 1967 ; Ogniben, 1963 ; Wezel, 1966, 1970). The prevailing opinion suggests an African origin, whereas for the French school the material comes from the north. Imbrication of resedimented larger foraminiferal tests shows a direction of the flows parallel to the dip of the strata. According to Chanell et al. (1990), Oldow et al. (1990) and Speranza et al. (2003) the rotation in the Madonie Mts. is approximatively clockwise, so it is preliminarily possible to assume a N-S paleodirection of the flows. V. SYSTEMATIC The suprageneric classification of Loeblich & Tappan (1987, 1992) is followed in this work. For each species has been drawn up a synonymic list, the most complete possible. The synonymic list of the taxa assigned to a species by an exclusive biometrical investigation, is necessarily incomplete, because of the necessity to compare other populations with the same methods.

4 200 A. BENEDETTI Fig. 3 : Distribution of the main larger foraminifera in the section PC. The presence of SBZ 18 at the base of Paleogene succession is uncertain ; no SBZ 20 (Late Priabonian) markers were found. Fig. 4 : Distribution of the main larger foraminifera in the section MM. The lack of the upper Eocene markers at the base of the Caltavuturo Fm. is noteworthy.

14 210 A. BENEDETTI Remarks : Montanari (1980) reported E. formosoides as a junior synonym of E. raulini Lemoine & Douvillé, 1904, differing only from the marked ornamentation of E. formosoides. Douvillé (1924) suggested that E. formosoides has an evident smaller embryo in respect to E. raulini. VI. CONCLUSIONS The displaced larger foraminifera tests occurring in some turbiditic layers into the clays of the Caltavuturo Fm, provide the opportunity to furnish the biostratigraphical pattern of an investigated outcrop at Portella Colla (Madonie Mts., Sicily). The occurrence of larger foraminifera is due to the frequence of the turbiditic events and so the lack of turbiditic layers at the base of the investigated sections prevents a detailed biostratigraphic resolution of the Late Eocene. According to the zonation proposed by Cahuzac & Poignant (1997) and Serra-Kiel et al. (1998) three biozones were surely recognized in the Caltavuturo Fm. clays : Borelis vonderschmitti, Discocyclina dispansa dispansa, Orbitoclypeus varians, Halkyardia minima and Heterostegina reticulata italica assemblage marks the SBZ 19, no SBZ 20 markers were found for the uppermost Priabonian. The lower Rupelian (SBZ 21) assemblages are dominated by Nummulites vascus with N. fichteli, Operculina complanata, Heterostegina sp., Halkyardia maxima, whereas the FO of Nephrolepidina praemarginata marks the upper Rupelian (SBZ 22A). A detailed biometrical investigation on Nephrolepidina populations from the investigated sections is still in progress with the aim to implement the biostratigraphic resolution of the Late Rupelian sediments (Benedetti & Pignatti, in prep). The imbrication of the Nephrolepidina tests points out on the N-S paleodirection of the flows, but it s impossible recognize the origin of these flows.
