Abstract

During late Cenozoic thrusting, the interior of the peri-Tyrrhenian orogenic belt in the southern Apennines underwent two episodes of nearly orthogonal extension. Early extension was oriented subparallel to the axis of the tectonic belt and formed in response to progressive thrust-belt arcuation. The length of the tectonic belt increased by approximately 50%, and the longitudinal strain was accommodated by low-angle normal faults concentrated in tectonic domains recording up to 150%-200% extension. Younger extension, oriented at a high angle to the orogen, was accompanied by Pliocene-Pleistocene uplift and by southeasterly migration of Tyrrhenian Sea rifting.

Abstract

The present invention concerns methods for obtaining from samples of rock of different natures, specifically chondrites, organic, metallorganic material or material of biological origin, and the materials themselves so obtained. In addition, the invention concerns their use in instrumentations exploiting their physical and physico-chemical properties, and fluorimetric methods to reveal such materials.

21. Complexity, self-organization and catalytic activities of peculiar (life-like) metallorganic entities generated on Earth from or below mineral iron surfaces

Abstract

We report evidence that both extraterrestrial and terrestrial minerals and rocks containing iron catalyze inorganic and organic reactions leading to production of metallorganic entities able to perform catalytic activities typical of modern life.While these properties indicate that they might be examples of prebiotic catalysts,complexity of their structures and chemical composition leave open the possibility that they might even represent a kind of non conventional form of pre-terrestrial life.

Abstract

A detailed carbon-isotope study has been carried out on a Santonian (Upper Cretaceous) carbonate platform succession which crops out at Monte Sant’Erasmo (southern Italy). Previous cm-scale studies on this succession have shown that high-frequency eustatic changes, due to Earth’s orbital fluctuations, controlled the hierarchical organization of the depositional and early diagenetic features in elementary cycles, bundles (groups of 3-5 elementary cycles) and superbundles (groups of 3-4 bundles). While the elementary cycles, which correspond to single beds, suggest a control due to the Earth’s precession, the bundles and superbundles record the short- (~100 kyr) and long- (~400 kyr) eccentricity periodicity respectively. The ä13C signal of the Monte Sant’Erasmo succession is cyclic in nature and may be considered to be a reliable proxy of the sedimentary evolution (and related sea-level history) of the analyzed sequence. The carbon-isotope cyclicity is recorded at bundle and superbundle level, but it is not evident at the scale of the elementary cycles, at least with the sampling interval used in this study. Spectral analysis of the ä13C record shows two main peaks corresponding to the short- and long- eccentricity periodicity, while the precession signal is not evident in the power spectrum. In addition, lithofacies analysis shows that in each bundle (and superbundle) higher C-isotope values occur in sediments characterized by marine cements, while lower values are normally found in more restricted deposits overprinted by early meteoric diagenesis. Early diagenesis, driven by periodic sea-level fluctuations, developed either in shallow-subtidal (marine diagenesis) or in subaerial-exposed (meteoric overprint) sedimentary environments and directly influenced the carbon-isotope signature. As a consequence, the ä13C record at Monte Sant’Erasmo reflects high-frequency climatic oscillations controlling both environmental and early diagenetic changes. The long-term isotopic record is similar to that of contemporaneous pelagic sections in England and elsewere in Italy. It is concluded that the ä13C signature of shallow-water carbonates, like those of Monte Sant’Erasmo, offers great potential for correlation with coeval sections, including those of the pelagic realm.
