“…Data sets for single locations are available, but these remain incomplete in regard to investigations concerning all geochemical, petrographic and microstructural parameters. Moreover, with the observation methods used so far (e.g., Attanasio et al. 2008), data clusters within a sampling site are too dispersed to allow any separation of outcrops within the site.…”

Provenance of Marbles From Naxos Based on Microstructural and Geochemical Characterization

A detailed quantitative microstructural study coupled with cathodoluminescence and geochemical analyses on marbles from Naxos demonstrates that the analysis of microstructures is the most sensitive method to define the origin of marbles within, and between, different regions. Microstructure examination can only be used as an accurate provenance tool if a correction for the second-phase content is considered. If second phases are not considered, a large spread of different microstructures occurs within sample sites, making a separation between neighbouring outcrops difficult or impossible. Moreover, this study shows that the origin of a marble is defined more precisely if the microstructural observations are coupled with cathodoluminescence data.a rcm_477 209..228

“…3, 5, and 9) show that Marmara Island is dominantly exposing rocks of the upper crystalline crust. More precisely, geological surface observations in this area (Aksoy 1995;Attanasio et al, 2008;25 Karacık et al, 2008;Ustaömer et al, 2009) differentiate three main rock types in outcrops: A Permian Marble unit in the North, an Eocene Granodiorite unit in the centre, and a Permian Metabasite in the South of Marmara Island. Considering the residual anomalies (Fig.…”

The Sea of Marmara, in Northwest Turkey, is a transition zone where the dextral North Anatolian Fault Zone (NAFZ) propagates westward from the Anatolian plate to the Aegean plate. The area is of interest in the context of seismic 10 hazard in the vicinity of Istanbul, a metropolitan area with about 15 million inhabitants. Geophysical observations indicate that the crust is heterogeneous beneath the Marmara Basin, but a detailed characterization of the crustal heterogeneities is still missing. To assess if and how crustal heterogeneities are related to the NAFZ segmentation below the Marmara Sea, we develop a new crustal-scale 3D density model which integrates geological and seismological data and is additionally constrained by 3D gravity modelling. This model indicates that the observed gravitational anomalies originate from significant 15 density heterogeneities within the crust. Two layers of sediments, one syn-kinematic and one pre-kinematic with respect to the Marmara Sea formation are underlain by a heterogeneous crystalline crust. A felsic upper crystalline crust (average density of 2720 kg.m -3 ) and an intermediate to mafic lower crystalline crust (average density of 2890 kg.m -3 ) appear to be crosscut by two large, dome-shaped mafic high-density bodies (average density of 3050 kg.m -3 ) of considerable thickness above a rather uniform lithospheric mantle (3300 kg.m -3 ). The spatial correlation between the bent segments of the fault and the location of 20the high-density bodies suggests that the distribution of lithological heterogeneities within the crust controls the rheological behaviour along the NAFZ, and consequently, influences fault segmentation and propagation dynamics.Solid Earth Discuss., https://doi.

“…On the whole, the Ephesos marbles are very much like many other medium‐grained varieties quarried around the Mediterranean basin and, therefore, difficult to discriminate. They lack any clear peculiarity, such as the very low EPR intensity shown by Proconnesos marbles (Attanasio et al. 2008), which, together with the support of other variables, leads to easy, reliable provenancing.…”

An updated database of Ephesos marbles including 244 samples from 16 quarrying districts is reported. The unknown Greco Scritto quarries near Hasançavuslar and the Bigio marbles from the quarries of Belevi and of Mt Panayir are also presented. The paper, however, is mostly devoted to the identification of the Ephesos white marbles, whereas the problems posed by the Bigio and Greco Scritto varieties are deferred to future work. The samples have been characterized by isotopic analysis, EPR spectroscopy and additional petrographic and optical properties. Owing to the complex geology of the region, the white marbles of Ephesos exhibit rather inhomogeneous properties and are conveniently classified into four marble groups, which can be almost completely discriminated. The problem of distinguishing the Ephesos white marbles from other similar varieties has been dealt with by statistically comparing the Ephesos samples with all the similar, medium‐grained varieties present in the marble database. Although some of the four Ephesos groups can be reliably identified, general solution of the discriminant problem is difficult. Historical archaeological information is needed to reduce the complexity of the problem by eliminating unlikely provenances. In this way relevant problems, such as the discrimination between Ephesos and Proconnesos marbles, can be solved.
