“…Although it is poorly documented in this sedimentary sequence, previous studies (Jacobs et al 1996) suggest that it could represent the onset of the CM7 event. This is consistent with later results from Spezzaferri et al (2001), who have documented the occurrence of CM7 in a comparable stratigraphic position in the nearby Hyblean Plateau (Sicily), described below.…”

“…The sedimentary section here termed the 'Palazzolo Section' spans 90 m through the upper part of the Tellaro Formation and the lower part of the Palazzolo Formation, recording deposition during the middle Miocene into the late Miocene (Mutti et al 1999;Spezzaferri et al 2001). The Tellaro Formation consist of marls and clay-rich carbonate mudstones containing planktonic and, subordinantly, benthic foraminifers and grades upward into the Palazzolo Formation, which consists of packstone to wackestone strata deposited in an outer neritic setting.…”

“…The contact between the Tellaro and Palazzolo formations is transitional and is expressed by the progressive appearance of distinctive carbonate-rich beds, initially alternating with marly intervals that tend to decrease in frequency up-section. Spezzaferri et al (2001) analysed in detail the microfossils assemblages (planktonic foraminifera and Bolboforma) and suggested that the sediments of the entire section were deposited without biostratigraphically recognizable hiatuses in an upper-slope environment across the middle-late Miocene boundary in the interval spanning from 11.9 Ma to c. 10.5Ma. A number of bioevents with stratigraphic significance have been recognized; details of the biozonations are given in Spezzaferri et al (2001).…”

The temporal variability of geochemical proxies can be used in time intervals characterized by global changes in marine chemistry to achieve improved stratigraphic correlation. The application of this approach in rocks lithified by cementation requires particular attention, as the original isotopic signature may have been modified by diagenetic processes and, when bulk samples are used, could reflect facies-specific compositional changes as opposed to primary changes in the water column. This paper examines sedimentological and chemostratigraphic records from outcrops in the central Mediterranean and cores drilled on the Marion Plateau by the Ocean Drilling Program (ODP) Leg 194, where heterozoan carbonates accumulated during the Miocene. Specifically, the paper addresses how facies and preservation of original marine signatures differentially affect the quality of the dataset. The analysis indicates that, in general, heterozoan systems, relative to their tropical counterparts, show good preservation of marine signatures. Chemostratigraphy offers a viable low-resolution alternative for dating platform sediments considering the general lack of biostratigraphic markers in these settings. It is stressed, however, that care must be taken when interpreting these values, especially when the dataset is at a low resolution or when post-depositional dolomitization took place. Furthermore, chemostratigraphy in shallow-water environments cannot be done without detailed facies analysis, as facies changes may impact bulk-rock stable isotope values.

“…Since at ODP Site 976 few upper Miocene sediments were recovered (Messinian-Tortonian/Serravallian; Comas et al, 1996), the reference section for the Middle Miocene can be considered the one drilled at DSDP Site 372, yielding a complete succession of Langhian bioevents (Abdul Aziz et al, 2008). Bolboforma compressispinosa, B. laevis and B. subfragoris, which are abundantly present in Middle to Late Miocene successions of the Western Mediterranean Sea (Spezzaferri et al, 2001), are also recorded at Site 372 (Poag and Karowe, 1986). Their presence in the foraminiferal assemblages of the mud-breccia suggests a strict affinity with the sedimentary sequence of Site 372.…”

Sedimentary sources of the mud-breccia and mud volcanic activity in the Western Alboran Basin

During the TTR-17 Leg 1 cruise in the West Alboran Basin, gravity cores were acquired from three mud volcanoes (MVs): Dhaka, Carmen and the recently discovered Maya. This paper presents micropaleontological and radiocarbon dating results from the three mud volcanoes, using cores containing mud breccias overlain by and interbedded with hemipelagic sediments. At Dhaka MV, the mud-breccia matrix contains very rare Holocene planktonic foraminifera associated with abundant reworked specimens of mixed Late Cretaceous to Mio-Pliocene age. At Carmen MV, the reworked assemblage is dominated by Miocene to Pliocene foraminifera occurring together with rare Late Cretaceous species while at Maya MV the mud-breccia matrix is characterized by the dominance of Santonian-Maastrichtian forms, with subordinate Tertiary species. Shallow-water benthic foraminifera such as Ammonia spp. and Elphidium spp. are generally rare and randomly distributed, but present at all studied sites. Based on these results, we suggest that the main sediment source of the mud-breccia extruded at Dhaka, Carmen and Maya MVs is possibly the lowermost overpressured olistostromic Unit VI (Aquitanian?-Burdigalian). Differences in the micropaleontological composition of the mud-breccia matrix at different sites are most likely due to differences in the main source layer and in the plumbing systems underneath the MVs. Radiocarbon dating of hemipelagic sediments associated to the mud-breccia allowed to define the age of the latest extrusion activities (>0.27 ka to > 15.6 ka BP), which seem to be episodic, short-lived and recurrent over thousands of years.

“…Faunal data in association with geochemical criteria (Mutti et al 1997(Mutti et al , 1999Spezzaferri et al 2001) suggest that nutrient supply was a major factor in the control of facies development and variability. Recently, Mutti and Bernoulli (2003) have provided further evidence of the role of trophic resource control on the basis of a study of sea-floor lithication in non-tropical ramp carbonates from the Maiella (Italy).…”

Research over the past several decades has clearly demonstrated that changes in the ocean environment have had major impacts on carbonate systems. Changes in climate, ocean circulation and seafloor spreading rates have influenced temperature and seawater chemistry, including carbonate saturation state and nutrient availability, and thereby have determined boundary conditions for the biota that form carbonate platforms. In turn, the biota determine accumulation rates and facies zonations, thus controlling platform geometry and facies dynamics. In the first section of this paper, we examine how nutrient availability influences carbonate facies associations. We first discuss the role of temperature and nutrient gradients in the modern ocean and their influence on biotic associations. Then we discuss how carbonate sedimentation can be characterized along nutrient gradients. In the second section, we review proxies currently used to reconstruct paleoproductivity in open ocean environments and discuss their applicability to neritic carbonate systems. We highlight the variety of existing proxies and their limitations, and suggest that multiple lines of evidence are needed for valid interpretations. Our short review discusses sedimentological, biogenic, and geochemical proxies that can be used to reconstruct past nutrient fluxes and to constrain paleoceanographic controls over the distribution of carbonate associations. However, it also reveals that more data and case studies are needed that integrate shallow and deep water carbonate sequences and elucidate the links between temperature vs. nutrient supplies changes and facies in ancient carbonate sequences.
